Face Mask Sensor to Detect COVID-19

Our breath holds a multitude of biomarkers, including potentially those indicating the presence of SARS-CoV-2, the virus responsible for COVID-19. Those infected with the virus are prone to exhale proteases, enzymes that speed up the breakdown of proteins, related to the new virus. This has led researchers at University of California, San Diego to (Read more...)

Cooling Vest Helps COVID Clinicians with Heat Stress

Researchers from the Radboud University Medical Center in The Netherlands have trialed cooling vests, originally designed for elite athletes, in nursing staff who have to put in long shifts in COVID-19 wards wearing full personal protective equipment (PPE). While essential, the protective equipment can lead to significant discomfort in the form of (Read more...)

10 Second COVID Antibody Test on a Chip

Researchers at Carnegie Mellon University have developed a microfluidic chip that can provide rapid COVID-19 antibody tests. The electrochemical test can detect very low concentrations of antibodies in blood samples, and transmits the results to a smartphone. The test could help to measure patient responses to vaccines and determine if they have be (Read more...)

Strados RESP Monitors Lung Sounds, Now FDA Cleared

Strados Labs, a company based in Philadelphia, PA, but with R&D offices in Atlanta, GA, won FDA clearance to introduce its RESP system for monitoring lung sounds. The RESP device has already been employed in clinical trials to help monitor how various therapies, patient reports, and other vital signs correlate with changes in lung sounds. [&hel (Read more...)

Real-time ELISA for Continuous Blood Testing

Though blood tests are a routine part of clinical care and hospital labs are able to quantify a myriad biomarkers, the results only indicate measurements at certain points in time. Continuous monitoring is available for only a few analytes such as glucose and oxygen. Now researchers at Stanford University have created a device that can […]

Artificial Attachments for Immune Cells Help Kill Tumors

Though immune cells have the capabilities to kill cancer cells, they’re often thwarted by cancer’s ability to evade detection. Researchers at Pennsylvania State University have now developed engineered natural killer cells that have a much better ability to find and kill cancerous cells. “We explored a novel method to engineer nat (Read more...)

Radiotherapy to Prevent Recurrence Post Brain Tumor Excision: Interview with Matthew Likens, President and CEO of GT Medical

GT Medical Technologies, a company based in Arizona, has developed the FDA-approved GammaTile system, which can provide localized radiation therapy for brain tumor excision sites. Its goal is to reduce tumor recurrence and enhance patient survival. The treatment consists of radiation seeds encased in a collagen substrate. These are easy to place at (Read more...)

Mitochondrial Transplantation to Treat Ischemia-Reperfusion Injury: Interview with Dr. Alexander Schueller, CEO of cellvie

cellvie, a company based in Houston, Texas, is developing a mitochondrial transplantation therapy to help reduce the damage caused by ischemia-reperfusion injury. The treatment involves delivering isolated mitochondria to cells that are affected by ischemia to help mitigate the dysfunctional metabolism that contributes to cell death in that context (Read more...)

Microbubbles Deliver Drugs Directly to Tumors

When fighting cancerous tumors, all too often the very drugs that can destroy a lesion tend to have significant negative effects on the rest of the body. Doses have to be maintained at moderate levels to avoid side-effects that are even worse than the disease. In light of this, researchers have been trying to develop […]

Paper Test for Quick Diagnosis of COVID-19

Researchers at the University of Illinois have developed a paper-based electrochemical diagnostic test for COVID-19 that can provide a result in just five minutes. The inexpensive test relies on the conductive properties of graphene and gold, and contains gold nanoparticles covered in sensitive nucleic acid probes that can bind to RNA from the SARS (Read more...)

Rapid PCR Chip for Infectious Disease Diagnostics

Researchers at Imperial College London have developed a tiny lab-on-a-chip that can perform PCR diagnostics in just a few minutes. Usually requiring bulky and expensive lab equipment, PCR is a gold standard diagnostic test for a variety of infectious pathogens, including bacteria and viruses, such as SARS-CoV-2. The new testing device is 1 cm in [& (Read more...)
