Small handheld device uses sound waves to detect certain clinical laboratory biomarkers in blood samples
University of Colorado Boulder researchers have developed a novel technology that uses sound waves to test for biomarkers in blood samples. In addition to being very easy to use, the handheld device is portable, highly sensitive, and delivers results in minutes. Though not ready for clinical use, this is yet another example of how researchers are developing faster diagnostic tests that can be performed in near-patient settings, and which do not have to be done in core laboratories, shortening time to answer.
The small instrument—referred to as an “acoustic pipette”—delivers sound waves to tiny particles within the device called “functional negative acoustic contrast particles” (fNACPs). These particles are cell-sized balls that can be customized with different coatings to identify specific biomarkers—such as viruses or proteins—in tiny blood samples, according to a news release.
To operate the device, the custom fNACPs are mixed with a drop of blood and then placed inside the acoustic pipette. The mixture is then blasted with sound waves, which forces particles carrying certain biomarkers to one side of the chamber where they are trapped while the rest of the blood is expelled. The captured biomarkers are then labeled with fluorescent tags and examined with lasers to determine how much of a specific biomarker is present.
“We’re basically using sound waves to manipulate particles to rapidly isolate them from a really small volume of fluid,” said Cooper Thome (above), PhD candidate in Chemical and Biological Engineering at UC Boulder and first author of the study in a news release. “It’s a whole new way of measuring blood biomarkers,” he added. Should further studies validate this approach, clinical laboratories may be able to use this technology to perform diagnostic tests with smaller volumes of patient samples.

Blood Testing Quickly and in Multiple Settings
To test their invention, the UC Boulder researchers examined antibodies against a protein called ovalbumin, which is found in egg whites and often used in the development of various vaccines. The scientists discovered that their device could detect the antibodies even in low amounts.
Current rapid tests known as lateral-flow assays can detect specific biomarkers in blood or urine samples but cannot determine how much of the biomarker is present. Enzyme-linked immunotherapy assays (ELISA), the leading clinical laboratory blood test, requires expensive equipment and can take hours to days for results to be received.
With UC Boulder’s new handheld device, tiny blood samples collected from a single finger prick could ensure accurate test results are available quickly at the point of care as well as outside of traditional healthcare settings. This would greatly benefit people in developing nations and underserved communities and may help ease test anxiety for individuals who are apprehensive about traditional blood tests.
“We’ve developed a technology that is very user friendly, can be deployed in various settings, and provides valuable diagnostic information in a short time frame,” said Wyatt Shields IV, PhD, Assistant Professor, Department of Chemical and Biological Engineering, UC Boulder, and senior author of the research in the news release.
“In our paper, we demonstrate that this pipette and particle system can offer the same sensitivity and specificity as a gold-standard clinical test can but within an instrument which radically simplifies workflows,” he added. “It gives us the potential to perform blood diagnostics right at the patient’s bedside.”
The graphic above, taken from UC Boulder’s published paper, illustrates how “fNACPs capture target biomarkers from whole blood samples. fNACPs are purified from blood components by acoustic trapping and captured biomarkers are labeled with a fluorescent antibody within the acoustic pipette. fNACP fluorescence is then measured to determine biomarker presence and concentration.” (Graphic/caption copyright: University of Colorado Boulder.)
Not Like Theranos
The authors of the UC Boulder study are cognizant of some skepticism surrounding the field of biosensing, especially after the downfall of Theranos. The scientists insist their technology is different and based on systematic experiments and peer-reviewed research.
“While what they (Theranos) claimed to do isn’t possible right now, a lot of researchers are hoping something similar will be possible one day,” said Thome in the news release. “This work could be a step toward that goal—but one that is backed by science that anybody can access.”
The device is still in its initial proof-of-concept stage, but the UC Boulder scientists have applied for patents for the apparatus and are searching for ways to scale its use and expand its capabilities.
“We think this has a lot of potential to address some of the longstanding challenges that have come from having to take a blood sample from a patient, haul it off to a lab, and wait to get results back,” Shields noted.
More research, studies, and regulatory reviews will be needed before this technology becomes available for regular, widespread use. But UC Boulder’s new blood testing device is another example of a research team using novel technology to test for known biomarkers in ways that could improve standard clinical laboratory testing.
Good behavior in federal prison by the disgraced founder of the now-defunct clinical laboratory company earned her the reduction in her original sentence of 11 years
Elizabeth Holmes, founder of failed clinical laboratory blood analysis company Theranos, continues to serve a lengthy term in prison after being convicted of multiple counts of fraud in 2022. However, now comes news that good behavior at her federal prison has shortened her sentence by nearly two years, according to NBC News.
The latest reduction took Holmes’ release from December 2032 to August 2032 in her “11-plus-year (135 month) prison sentence for wire fraud and conspiracy,” NBC reported, adding that Holmes, though Theranos, “defrauded investors out of hundreds of millions of dollars.”
Holmes entered FPC Bryan, a federal prison camp in Bryan, Texas, to begin serving her term in May 2023.
“Holmes had her sentence computation done within the first 30 days of arriving at Bryan,” Forbes reported. Given Good Conduct Time (GCT), Holmes was given 608 days off calculated from the start of her sentence. “If she were to incur a disciplinary infraction, some of those days can be taken away. Most all prisoners receive 54 days per year of GCT based on the sentence imposed,” Forbes added.
The Federal Bureau of Prisons (BOP) can additionally shave off up to a year through its Residential Drug Abuse Program (RDAP). “To qualify, the prisoner must not have a disqualifying offense, such as terrorism or gun charge, and voluntarily provided information that they had a drug or alcohol problem prior to their arrest. This disclosure has to be done prior to sentencing during the pre-sentence interview and must be also documented in the Presentence Report, a detailed report used by the BOP to determine things like classification and programming for the prisoner,” Forbes noted.
Additionally, the federal First Step Act, which President Trump signed into law in 2018, enables Holmes to “earn up to 365 days off any imposed sentence by participating in prison programming such as a self-improvement classes, a job, or religious activities,” Forbes reported.
Given the opportunities to shave time off her sentence, Holmes may ultimately serve just 66 months of her original 135 month sentence in federal prison.

Fall of a Silicon Valley Darling
Theranos boasted breakthrough technology and became an almost overnight sensation in Silicon Valley when it burst onto the scene in 2003. Holmes, a then 19-year-old Stanford University dropout, claimed Theranos would “revolutionize the world of blood testing by reducing sample sizes to a single pin prick,” Quartz reported.
The height of the company saw Theranos valued at $9 billion, which came crashing down when the Wall Street Journal reported in 2015 that questionable accuracy and procedures were being followed by the company, CNN reported.
“From the moment Holmes concluded her presentation and stepped off the podium on Monday afternoon, she, her company, and her comments became the number one subject discussed by attendees in the halls between sessions and in the AACC exhibit hall,” Michel wrote, adding, “The executive team and the investors at Theranos have burned through their credibility with the media, the medical laboratory profession, and the public. In the future, the company’s claims will only be accepted if presented with scientific data developed according to accepted standards and reviewed by credible third parties. Much of this data also needs to be published in peer-reviewed medical journals held in highest esteem.”
Ultimately, investors who had jumped in early with financial support for Theranos were defrauded of hundreds of millions of dollars and Holmes was sentenced to 11 years/three months behind bars.
“Theranos had only ever performed roughly a dozen of the hundreds of tests it offered using its proprietary technology, and with questionable accuracy. It also came to light that Theranos was relying on third-party manufactured devices from traditional blood testing companies rather than its own technology,” CNN added.
The company shut down in 2018.
And so, the Elizabeth Holmes saga continues with reductions in her prison sentence for “good behavior.” The irony will likely not be lost on the anatomic pathologists, clinical laboratory scientists, and lab managers who followed the federal trials.
Theranos founder and former CEO continues down the path she began by defrauding her investors and lying to clinical laboratory leaders about her technology’s capabilities
As a result of the ban, Holmes is “barred from receiving payments from federal health programs for services or products, which significantly restricts her ability to work in the healthcare sector,” ARS Technica reported.
So, Holmes, who is 39-years old, is basically banned for life. This is in addition to her 11-year prison sentence which was paired with $452,047,200 in restitution.
“The exclusion was announced by Inspector General Christi Grimm of the Department of Health and Human Services’ Office of Inspector General,” ARS Technica noted, adding that HHS-OIG also “excluded former Theranos President Ramesh “Sunny” Balwani from federal health programs for 90 years.” This is on top of the almost 13-year-long prison sentence he is serving for fraud.
“The Health and Human Services Department can exclude anyone convicted of certain felonies from Medicare, Medicaid, and Pentagon health programs,” STAT reported.
“Accurate and dependable diagnostic testing technology is imperative to our public health infrastructure,” said Inspector General Christi Grimm (above) in an HHS-OIG statement. “As technology evolves, so do our efforts to safeguard the health and safety of patients, and HHS-OIG will continue to use its exclusion authority to protect the public from bad actors.” Observant clinical laboratory leaders will recognize this as yet another episode in the Elizabeth Holmes/Theranos fraud saga they’ve been following for years.

Why the Ban?
“The Office of Inspector General (OIG) for the Department of Health and Human Services (HHS) cited Holmes’ 2022 conviction for fraud and conspiracy to commit wire fraud as the reason for her ban,” The Hill reported.
“False statements related to the reliability of these medical products can endanger the health of patients and sow distrust in our healthcare system,” Grimm stated in the HHS-OIG statement, which noted, “The statutory minimum for an exclusion based on convictions like Holmes’ is five years.
“When certain aggravating factors are present, a longer period of exclusion is justified,” the statement continued. “The length of Holmes’ exclusion is based on the application of several aggravating factors, including the length of time the acts were committed, incarceration, and the amount of restitution ordered to be paid.”
Rise and Fall of Elizabeth Holmes
Readers of Dark Daily’s e-briefs covering the Holmes/Theranos fraud saga will recall details on Holmes’ journey from mega success to her current state of incarceration for defrauding her investors.
In November 2022, she was handed an 11-year prison sentence for not disclosing that Theranos’ innovative blood testing technology, Edison, was producing flawed and false results. Theranos had “raised hundreds of millions of dollars, named prominent former US officials to its board, and explored a partnership with the US military to use its tests on the battlefield,” STAT reported.
To get Holmes physically into prison was a journey unto itself. At one point, evidence showed her as a potential flight risk. “In the same court filings, prosecutors said Holmes and her partner, William Evans, bought one-way tickets to Mexico in December 2021, a fact confirmed by her lawyers,” Dark Daily’s sister publication The Dark Report revealed in “Elizabeth Holmes’ Appeal Questions Competence of CLIA Lab Director.”
Drama around her move into prison continued. “The former CEO’s attorneys are making last-minute legal moves to delay her prison sentence while she appeals her guilty verdict,” Dark Daily reported.
At the same time, Holmes appeared to be on a mission to revamp her public image.
In the Times piece, Holmes talked about her plans to continue to pursue a life in healthcare. “In the story, Holmes contended that she still thinks about contributing to the clinical laboratory field. Holmes told The Times that she still works on healthcare-related inventions and will continue to do so if she reports to prison,” The Dark Report covered in “Elizabeth Holmes Still Wants ‘To Contribute’ in Healthcare.”
In the meantime, her legal fees continued to mount beyond her ability to pay. “Holmes’ prior cadre of lawyers quit after she could not compensate them, The Times reported,” The Dark Report noted. “One pre-sentencing report by the government put her legal fees at more than $30 million,” according to The New York Times.
Apparently, this closes the latest chapter in the never-ending saga of Elizabeth Holmes’ fall from grace and ultimate conviction for defrauding her investors and lying to healthcare executives, pathologists, and clinical laboratory leaders.
Founder of now defunct clinical laboratory testing company was supposed to report to prison April 27, but a last-minute legal challenge has delayed that judge’s order
Anatomic pathologists and clinical laboratory leaders who are following the continuing saga of Theranos and Elizabeth Holmes may be interested to learn that the former CEO’s attorneys are making last-minute legal moves to delay her prison sentence while she appeals her guilty verdict. At the same time, Holmes appears to be on a mission to revamp her public image.
Apparently, the twists and turns in Holmes’ never-ending story are not yet over when it comes to Theranos, its maligned clinical laboratory technology, and the company’s convicted founder.
On May 7, The New York Times (NYT) profiled Holmes in a massive, 5,000-word story that attempted to portray her as a flawed businessperson who now prefers a simpler life with her partner and two young children.
“I made so many mistakes and there was so much I didn’t know and understand, and I feel like when you do it wrong, it’s like you really internalize it in a deep way,” disgraced Theranos founder Elizabeth Holmes recently told The New York Times. Anatomic pathologists and clinical laboratory directors impacted by the revelation that Theranos hide the fact that its blood testing technology was faulty may not sympathize with Holmes’ position.

Legal Team Secures Last-Minute Delay in Holmes’ Surrender
Holmes admitted to the news outlet that the deep voice she used in public, along with her black turtleneck sweaters, were part of a character she created.
“I believed it would be how I would be good at business and taken seriously and not taken as a little girl or a girl who didn’t have good technical ideas,” Holmes told the NYT. “Maybe people picked up on that not being authentic, since it wasn’t.”
However, on April 26, the 9th Circuit Court of Appeals stayed her surrender date until that court rules on Holmes’ latest bid to stay free while she appeals her conviction, The Washington Post reported.
Just days earlier on April 10, a district court judge ruled that Holmes would not stay free while her appeal progresses. The 9th Circuit announcement curtailed the district court ruling. It is not known when the 9th Circuit will issue a decision in the matter.
New York Times Reports on Holmes’ Change in Personality
The somewhat odd New York Times profile of Holmes varied between reflections on her past crimes and on her current personal life, where she is known as “Liz.”
“In case you’re wondering, Holmes speaks in a soft, slightly low, but totally unremarkable voice—no hint of the throaty contralto she used while running her blood-testing startup Theranos, now defunct,” the NYT reported.
Holmes still lives in California with her partner, Billy Evans (whose parents own a luxury hotel chain), and their two children: a son who is almost two years old and a daughter born in February. She works at home for a rape-crisis hotline.
Balwani’s Role in Theranos Again Publicly Debated
In the NYT interview, Holmes talked about being raped while a student at Stanford University and about alleged abuse from her Theranos business partner and former lover, Ramesh “Sunny” Balwani.
Balwani, Theranos’ former President and Chief Operating Officer, began his 12-year, 11-month prison sentence on April 20 in a Southern California facility for his role in defrauding Theranos investors, KTVU TV reported. Balwani has also appealed his conviction on the 12 fraud charges.
Holmes reiterated to the NYT past statements she made in court that Balwani allegedly exerted social and sexual control over her when they both worked at Theranos and were in a romantic relationship.
“She lived by entrepreneurial tenets that she said Balwani told her she needed to follow in order to succeed,” the NYT reported. “These included not sleeping for more than five hours, going vegan, getting to the office daily by 5 a.m., no alcohol.”
“[I] deferred to [Balwani] in the areas he oversaw because I believed he knew better than I did,” including on clinical lab activities at Theranos, Holmes said.
Balwani’s attorneys dismissed Holmes’ allegations, as they have in the past.
Clinical laboratory professionals can reasonably make two broad observations from the continuing saga of Theranos and Elizabeth Holmes:
Justice for healthcare crimes is often deferred for those who have influence and money.
Holmes’ image overhaul may be a last-ditch effort to sway public opinion about her, in the event that she receives a new jury trial as a result of her appeal.
Dark Daily will continue to keep you updated on further developments in this case.
New lawsuit contends that the promissory notes Holmes allegedly issued on behalf of defunct clinical laboratory company Theranos are now overdue
Just weeks before Elizabeth Holmes is scheduled to begin her prison term for conviction in the federal investor fraud case related to now-defunct clinical laboratory company Theranos, the long-running legal saga of the former company founder/CEO continues to bring new twists.
This time, news emerged via a lawsuit that Holmes allegedly owes $25 million to Theranos creditors. CNBC obtained a copy of the suit and detailed its contents in a March 17 case update.
Theranos ABC, a company set up on behalf of the creditors, alleged in the lawsuit that “Holmes has not made any payments on account of any of the promissory notes,” CNBC reported. The suit was filed in Superior Court of California Count of Santa Clara.

Holmes Allegedly Issued Three Promissory Notes
The complaint stated that Holmes allegedly executed the following three promissory notes while she was still CEO at Theranos:
August 2011 in the amount of $9,159,333.65.
December 2011 in the amount of $7,578,575.52.
December 2013 in the amount of $9,129,991.10.
A promissory note is a written promise to pay a party a certain sum of money with a specified due date for the repayment of principal and interest.
“Theranos ABC has demanded payment of promissory note one and promissory note two from Holmes, but Holmes has failed to pay any amounts on account of promissory note,” according to the lawsuit, CNBC reported. The first two notes are overdue, and the third note is due in December.
Elizabeth Holmes’ Prison Term Could Be Delayed
News of the lawsuit, which was filed in December 2022, came to light at a court hearing on March 17. During that hearing, Judge Edward Davila heard arguments about whether Holmes should remain free pending her appeal. She is otherwise scheduled to report to prison on April 27 to begin her sentence after being convicted in January 2022 of defrauding Theranos investors.
Davila, who oversaw Holmes’ criminal case, is expected to issue a decision about her freedom during the appeal early this month. The judge is also weighing options for Holmes to pay restitution to her victims.
Prosecutors have asked that she pay back $878 million to Theranos’ former investors and other victims, according to court records reviewed by Dark Daily. The government has argued in court papers that Holmes continues to live a wealthy lifestyle despite her claiming she has no meaningful assets since the collapse of Theranos and her trial.
“Defendant has lived on an estate for over a year where, based upon the monthly cash flow statement defendant provided to the US Probation Office, monthly expenses exceed $13,000 per month,” according to court documents filed by prosecutors ahead of the March 17 hearing. “Defendant asserted that her partner pays the monthly bills rather than her but also listed her significant other’s salary as ‘$0.’”
Holmes’ attorneys argued that the government cannot take an “all or nothing” approach to restitution, and that payments should only be made to investors who testified during the trial, the Associated Press reported.
For Victims, Full Restitution Can Be Rare
The federal Department of Justice (DOJ) acknowledges in its overview of restitution that victims often never collect what they are owed by guilty parties.
“The chance of full recovery is very low,” the DOJ notes. “Many defendants will not have sufficient assets to repay their victims. Many defendants owe very large amounts of restitution to a large number of victims. In federal cases, restitution in the hundreds of thousands or millions of dollars is not unusual. While defendants may make partial payments toward the full restitution owed, it is rare that defendants are able to fully pay the entire restitution amount owed.”
Clinical laboratory professionals will note the irony that one of the biggest convicted fraudsters in US history is now largely attempting to avoid punishments associated with her crimes. If Judge Davila agrees to let Holmes remain free pending her appeal, she could stay out of prison for years and perhaps not have to pay restitution for that length of time as well.
The coming weeks will prove to be pivotal in the final outcome of the case.
