Washable Face Masks Thanks to Electrospun Nanofibers

One big reason there’s a shortage of face masks that can block the spread of the COVID-19 virus is that they’re single-use devices. The exterior may be contaminated and there’s a good chance that keeping the mask and using it again could transmit the infection, particularly when masks are used around known COVID-19 patients. Becau (Read more...)

Open Source Face Shield to Help Block COVID-19

While face masks that block particles from coming into the lungs via the nose and mouth are important to prevent the spread of COVID-19, the eyes and the rest of the face can also be a pathway for the disease to find its way into the body. There are now a number of projects around […]

Robots to Greet, Triage Incoming Coronavirus Patients

Because of the COVID 19 situation, clinical facilities are currently faced with the issue of trying to keep interactions between potential patients and staff at a minimum. Face masks and other precautions help, but modern technology is allowing some tasks to be completely performed without human staff. Wegree, a company based in Poland, makes human (Read more...)

Intel’s Chip Learns to Sniff for Hazardous Chemicals

Researchers at Intel Labs and Cornell University have utilized an unusual “neuromorphic chip” to quickly learn the signature smell of ten different hazardous chemicals and spot their presence quicker than ever before. The Loihi chip, as it is called, mimics how our brains classify and identify unique smells that our noses detect, retain (Read more...)

Cold Plasma Reactor to Kill Airborne Viruses

The ongoing coronavirus outbreak is making it clear that the world needs innovative new tools for slowing the spread of infections. While there are a number of well-known methods of disinfection that are being employed, the air itself serves as a channel through which viruses can spread. Researchers at the University of Michigan and University [&he (Read more...)

Antimicrobial Layer for Plastic Food Wrap Developed

Bacteria can take a ride and proliferate on the plastic wrap that foods are commonly packaged in. Researchers at Penn State have developed a way to bond a non-toxic transparent antimicrobial material to the ubiquitous polyethylene wrap that meats, vegetables, and mushrooms are sold in. The antimicrobial layer is made of a pullulan-based biopolymer, (Read more...)

Body Worn Gas Sensor Sticks to Skin

Potential exposure to dangerous chemicals is a reality for many people working in mining and manufacturing, as well as medicine. While spills of liquids are easily detected, many gases are not. Sensitive wearable gas sensors stuck to the skin would be useful for gas exposure detection, but these devices have to be flexible, need a […]

Handheld Device to Capture and Identify Viruses in Minutes

Researchers at Penn State have developed a handheld device called VIRRION that can capture and identify viral particles in samples within minutes. The device contains a “forest” of carbon nanotubes that capture and sort viral particles depending on their size, and then users can identify the viruses using Raman spectroscopy. The techniq (Read more...)

MolecuLight FDA Cleared to Detect Bacteria Infected Wounds

Knowing whether a wound is infected by a bacterial colony is important for monitoring patients and deciding the course of treatment. Currently, the standard of care is simply to assess the clinical signs and symptoms (CSS) related to the wound in question, but bacterial infections of wounds are typically not obvious until they’re at an [&hell (Read more...)

Smart Microscope Learns to Diagnose Infectious Diseases

Experienced professionals tend to be better than rookies partly because they know how to use the tools of their trade more effectively. Cytologists who evaluate cells under a microscope become more consistent and accurate when they know how to prep their apparatus to produce clear images. Researchers at Duke University have now given a microscope [ (Read more...)

Low Cost Turbidity Measurements Using a Fitness Tracker

Continuous monitoring of bacterial growth is a critical step in the biotechnology industry and in biological labs. These measurements are typically taken using large and bulky spectrophotometers that do not fit into incubators for real-time monitoring. Moreover, continuous monitoring is labor-intensive as it requires multiple samplings. Recent deve (Read more...)
