The RADxSM Tech Process: Accelerating Innovation for COVID-19 Testing
In the wake of the COVID-19 pandemic, the need for rapid and accurate diagnostic testing across populations quickly became evident. In response, the National Institutes of Health (NIH) was determined not only to invest heavily in this area but to change the process by which grant proposals were reviewed and funded in order to spur faster development of viable technologies. The Rapid Acceleration of Diagnostics (RADx) initiative was designed to speed innovation, commercialization, and implementation of potential COVID-19 diagnostic technology... Read more

The PACE of Change
At a time when a global vaccine program is being rolled out at unprecedented speed, the world is more aware than ever before of the wonders of medical science. There are, however, many diseases that remain beyond the reach of modern medicine and the potency of some of our most widely used therapies are waning... Read more
Finding New Ways To Treat Tremors
An estimated ten million people in the United States have a condition known as essential tremor (ET). Yet although it’s been recognized for over a century—it was originally known as senile tremor—there is relatively little awareness of it as a distinct medical condition. Sometimes mistaken for Parkinson’s disease, ET can lead to shaking of the arms and hands, and sometimes the head or torso. When severe, it can interfere with eating or drinking, writing, dressing, and even make some tasks impossible. Now, new approaches for treating the condition are emerging, potentially offering options to many patients whose life activities have been curtailed by ET... Read more
Medical Care in the Digital Era
Electronic health records (EHRs), virtual office visits, and health-related apps are priming the path toward a future vision of medical care in the digital age. That future includes streamlining patient-provider interactions, making good use of the wealth of collected data, and ultimately improving all levels of care from prevention to diagnosis, treatment, and outcomes...

Fighting COVID-19 With Lung-Chips
The novel coronavirus is a new kind of enemy. Now, the United States Army has added a cutting-edge tool to its arsenal to better understand this threat: “organs-on-chips” that recapitulate the microarchitecture and function of living human lungs... Read more
Can Coverscan Help COVID-19 Survivors?
At the start of the COVID-19 pandemic, doctors and hospitals were overburdened from patients suffering from the immediate, acute effects of the virus. But as time went on, it turned out that even the patients who survived—or had mild symptoms and didn’t require hospitalization—weren’t fully recovered... Read more

Development and Characterization of a Non-Thermal Plasma Source for Therapeutic Treatments
A non−thermal plasma (NTP) system constituted by a radiofrequency generator directly coupled to a treatment probe is described. The NTP generated was analyzed and characterized to determine a plasma safety profile and a spreading technique to be used on heat−sensitive matter. When NTP interacts with surrounding air particles produces reactive oxygen and nitrogen species that exhibit bactericidal and antiseptic effects due to their strong biochemical reactivity. Afterward, the NTP source was validated through bacterial deactivation trials, biological tests and promoting and in vivo wound closure performed in mice. NTP source demonstrated faster wound healing than that performed with conventional treatments... Read more
Rapid impedance spectroscopy for monitoring tissue impedance, temperature, and treatment outcome during electroporation-based therapies
Electroporation-based therapies (EBT) employ high voltage pulsed electric fields to permeabilize tumor tissue; this results in a detectable impedance change. Impedance characterization with a potentiostat is limited by acquisition time (~10s) as this timeframe is larger than pulse periods used with EBTs (~1s). Here, we develop a rapid electrical impedance spectroscopy (EIS) method for impedance characterization (<1s) of electroporation and thermal effects during irreversible electroporation. A biphasic rectangular chirp signal allows for impedance measurements between 1.8 kHz – 4.93 MHz. For the first time, we show impedance analysis at high frequencies (~1 MHz) can delineate thermal effects from electroporation effects... Read more

Innovation Is Tied to Optimism
I wonder, when this coronavirus pandemic is finally behind us, if we will have seen a pause in the technological and social progress that had been happening at such a breakneck pace before the illness had spread throughout the world. I wonder if the attention that we have been forced to place on our own survival has stolen from our ability to innovate and create. This, despite the extra time that many of us have had to endure away from our jobs and normal activities, and the time that we would now have to dream up new ­possibilities... Read more
