Synthetic Antibody Prevents COVID Virus Replication

Although a few types of COVID-19 vaccines have begun to be distributed around the world, a unique technology, developed at University of California, San Francisco, may offer an even more direct way to prevent the coronavirus from multiplying within the body. The UCSF team created a synthetic antibody that prevents SARS-CoV-2, the virus that causes (Read more...)

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...)

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...)

Rapid Identification of Antibiotic-Resistant Infections: Interview with Jong Lee, CEO at Day Zero Diagnostics

Antibiotic resistance is a growing concern, with some predictions suggesting that routine surgery could be unacceptably risky in a future where many antibiotics have become obsolete. Part of the problem lies in the time it takes clinicians to diagnose an antibiotic-resistant infection. Current techniques involve lab technicians culturing a bacteria (Read more...)

Elastomeric Respirator Mask Senses Fit and Filter Saturation

Researchers at Brigham and Women’s Hospital and Massachusetts Institute of Technology have designed a new respirator, conceived as an improvement on standard N95 masks. The transparent respirator contains sensors that allow users to know if the mask is fitting snugly and alerts them when the filters need to be replaced. The mask, called the t (Read more...)

Inhalable Nanobody Therapy Deactivates SARS-CoV-2

Researchers at the University of Pittsburgh have developed a new antibody-type therapy for SARS-CoV-2, the causative virus for COVID-19. The treatment exploits “nanobodies” – tiny antibody fragments – that are harvested from llama blood. The new nanobody therapy can be used in an inhalable form that may deactivate the virus (Read more...)

Microneedle Bandage Detects Malaria in Minutes

Researchers at Rice University have developed a microneedle patch that can rapidly detect the presence of malaria in interstitial fluid. Users can apply the patch to their skin, as you would a bandage, and then obtain a result in as little as 20 minutes. The technology is low-cost and requires no expertise to utilize. Malaria […]
