Sound Waves Move Individual Droplets Inside Microfluidic Devices
Microfluidic devices are analogous to circuit boards, and they can be programmed to perform all kinds of laboratory tasks on a small scale. They have the potential to perform all kinds of medical tests involving body fluids in a short time and using very small samples. While circuit boards pass electricity, which can be abstracted […]
Breathalyzer to Detect COVID-19 in Seconds
Being able to tell, in a matter of seconds, whether someone is infected with the virus that causes COVID-19 would certainly help put a halt to the ongoing pandemic. Existing tests typically involve a deep nasal swab to obtain enough fluid sample, which has to be transferred to a laboratory machine for processing, with the […]
Microfluidic Device Mimics Blood Vessels to Test Clotting
Researchers at Texas A&M University have developed a microfluidic device that mimics the complex architecture of vasculature to better study blood clot treatments. The device includes channels with spirals, bends, and curves that are similar to those found in blood vessels, and which can influence blood clotting. Besides being biomimetic, the d (Read more...)
Smart Textile Fibers to Measure Wearer’s Health
At the Swiss Federal Institute of Technology Lausanne (EPFL) researchers have developed special textile threads that can be used to detect slight variations in how a fabric is stretched, the pressures that are applied to it, and even the torque that twists it. The capability may end up being used in clothing and even bed […]
(Read more...)Microfluidic Test for Viral Antibodies Takes Just 20 Minutes
Researchers at Hokkaido University in Japan have developed a microfluidic test that can detect antibodies against a viral infection. So far, the test has been optimized to detect avian flu, but could be adapted to detect antibodies against the virus causing COVID-19. The device can provide a result in as little as 20 minutes and […]
Quick Urine Test for Metabolic Precursors of Kidney Stones
Researchers from Penn State and Stanford University have developed a 30-minute urine test to measure levels of substances that can contribute to kidney stone formation. The test could help patients to find out if they are prone to developing kidney stones or to monitor their progress in avoiding kidney stone formation through treatment or dietary [ (Read more...)
Fidget Spinner for Rapid Detection of Urinary Tract Infections
More than half of all women experience at least one episode of urinary tract infection (UTI) in their lifetime, with men also facing increasing risks of infection as they age. Current detection of UTIs rely on patients reporting symptoms followed by a lab culture of the urine for known bacterial culprits, which typically takes a […]
Smartphone Measures Hemoglobin Levels in Photos of Eyelids
Anemia is properly diagnosed using a blood test that measures hemoglobin, but simply looking behind a patient’s eyelid can be a pretty good alternative if you know how red the tissue is supposed to be. Now, a team at Purdue University has developed a technology that lets a clinician use smartphone pictures of the inner […]
Flexible Sensors Measure Vitamin C Levels in Sweat
Researchers at the University of California San Diego have developed flexible sensors that can be worn on the skin to sensitively track vitamin C levels in sweat. The devices could be useful in helping wearers to maintain optimal levels of the vitamin, which is important for a healthy immune system, and could be particularly useful […]
Philips Ultrasounds Cleared in U.S. to Manage COVID Complications
The FDA has granted Philips 510(k) clearance for its ultrasound systems to be used to address lung and cardiac complications that arise in COVID-19 patients. The clearance encompasses the firm’s EPIQ series, Affiniti series, Lumify, CX50 and Sparq diagnostic ultrasounds, and for offerings such as the QLAB Advanced Quantification Software. Ult (Read more...)
Butterfly TeleGuidance for Remote Ultrasound Exams During COVID Pandemic
Telemedicine has been around for over a decade in various forms, but the COVID-19 epidemic has turned a convenience into a necessity. Clinical practices that never seriously considered using telemedicine are now performing virtual house calls with their patients. However, although it’s possible to do a lot through a video call, many procedure (Read more...)
AiRTouch Portable X-Ray Receives FDA Clearance, Can Be Used for COVID Diagnosis
Aspenstate announced that it has received FDA clearance for the AiRTouch, a lightweight portable X-ray system that could be particularly useful for quickly obtaining chest X-rays of COVID-19 patients. The handheld device weighs in at 5.5 pounds (2.5 Kg) and resembles a large digital camera with a touchscreen. AiRTouch acquires images with the (Read more...)
BioButton to Help Track COVID, Ensure Safe Return to Work
BioIntelliSense, a Silicon Valley company, is unveiling its FDA cleared BioButton device that may help with tracking symptoms of COVID-19 in potential patients and help society return to a normal state of affairs. The BioButton is about the size of a large coin and, with the help of accompanying applications and triage dashboards, it can […]
