A portable particle detector can determine aerosol concentrations in public spaces — ScienceDaily

Because of the role they play in coronavirus transmission, understanding aerosol concentrations and persistence in public spaces can help determine infection risks. However, measuring these concentrations is difficult, requiring specialized personnel and equipment. That is, until now. Researchers from the Cardiology Centers of the Netherlands and the University of Amsterdam demonstrate that a commercial hand-held […]

New lab-on-a-chip infection test could provide cheaper, faster portable diagnostics

The chip, developed at Imperial College London and known as TriSilix, is a ‘micro laboratory’ which performs a miniature version of the polymerase chain reaction (PCR) on the spot. PCR is the gold-standard test for detecting viruses and bacteria in biological samples such as bodily fluids, faeces, or environmental samples. Although PCR is usually performed […]

Low-cost, portable, and rapidly deployable ventilators

The procurement and maintenance of high‐end ventilators limits their use in emergency situations. By removing the “frills”, researchers create a viable alternative. Ventilators have been one of the mainstays of combatting lung infections due to COVID-19. However, their enormously high cost (up to 50,000 USD) precludes a hospital’s ability to stockpile them for emergencies, such […]

A new portable device can reveal a chili pepper’s heat

Just how hot is your chili pepper? A new chili-shaped device could quickly signal whether adding the pepper to a meal might set your mouth ablaze. Called the Chilica-pod, the device detects capsaicin, a chemical compound that helps give peppers their sometimes painful kick. In general, the more capsaicin a pepper has, the hotter it […]
