Sticker on Skin Diagnoses Cystic Fibrosis in Real-time
Researchers at Northwestern University have developed a sticker that can measure chloride levels in sweat in real-time through a simple color change. The sticker is applied to the skin and wicks sweat inside itself through a set of microfluidic channels, where an onboard bioassay measures chloride levels, a marker of cystic fibrosis. The technology (Read more...)
Microneedle Patch with Fluorescent Nanolabels Detects Antibodies in Skin
Researchers at the Washington University in St. Louis have developed a microneedle patch that can help to detect small amounts of antibodies in interstitial fluid. The painless technology could provide an alternative to blood draws for antibody tests, such as those used in the COVID-19 response. The new technology overcomes a bottleneck with many m (Read more...)
CES 2020: OMRON VitalSight Remote Patient Monitoring
Remote patient monitoring has gone from novelty to necessity in a matter of months thanks to the COVID-19 pandemic. In reality, allowing clinicians to keep an eye on their patients provides a number of important benefits even during “normal” times. At this year’s CES, which is a virtual event this year, Omron presented its VitalSi (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 […]
BIOMONITOR IIIm Injectable Cardiac Monitor Can Now Look for Signs of Fever
BIOTRONIK won FDA clearance for the Vital Data Sensor, a body temperature component within the BIOMONITOR IIIm injectable cardiac monitor (ICM). The ICM is designed to help cardiologists detect and diagnose cardiac arrhythmias remotely, but thanks to the Vital Data Sensor the implant now has an additional role in monitoring for signs of fever. This (Read more...)
Sleep Apnea Testing at Home: Interview with Laurent Martinot, CEO of Sunrise
Obstructive sleep apnea is very common and is associated with a variety of serious health issues, such as cardiovascular disease and diabetes. Getting a proper diagnosis is hampered by the need for patients to visit a sleep clinic and undergo a polysomnography. This gold-standard test is complicated and requires specialized staff to interpret the r (Read more...)
Smart Ring Monitors Body Temperature, May Spot COVID Fever Early
A team of researchers, including those at the University of California, San Francisco and University of California, San Diego, has tested the potential of a smart ring, that can collect health data, including temperature and heart rate, to detect fever associated with COVID-19. In a proof-of-concept study, the researchers showed that the ring, deve (Read more...)
Saliva COVID Test Uses Smartphone for Results in 15 Minutes
Scientists at Tulane University have reported a new COVID-19 saliva test that uses a smartphone to provide results in as little as 15 minutes. Similar to technology from UC Berkeley that we reported on last week, the new test uses CRISPR technology and does not involve polymerase chain reaction (PCR) that, though accurate, is slow […]
Siemens epoc NXS Host Mobile Computer Cleared to Help Point of Care Blood Testing
Siemens Healthineers won both EU and US regulatory approval to introduce its epoc NXS Host mobile computer for the epoc Blood Analysis System. The Android smartphone provides an app-based intuitive interface that replaces the older interface that had over two dozen physical buttons and a relatively low resolution screen. The accompanying app is des (Read more...)
Smart Stethoscope Helps Monitor and Diagnose Respiratory Conditions: Interview with Helena Binetskaya, CEO of Healthy Networks
LungPass, an AI-powered Bluetooth stethoscope has been developed by Healthy Networks, a company based in Talinn, Estonia. The device can analyze sounds from the lungs and help to diagnose or monitor a variety of respiratory conditions, with an initial focus on pneumonia and COPD. The aim was to create a low-cost (the device costs as […]
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...)
CRISPR Test Uses Cell Phone Camera to Detect SARS-CoV-2
