Sweat Powered Battery for Wearable Medical Devices

Researchers at Nanyang Technological University in Singapore created a flexible battery that is powered by sweat. The device could provide a new way to energize medical wearables, some of which already use sweat to detect or monitor disease. The stretchable device incorporates silver flakes that clump together and generate a small electrical curren (Read more...)

Microwave Sensor for Rapid Antibiotic Susceptibility Testing

Researchers at University of British Columbia Okanagan campus have developed an inexpensive and portable microwave sensor that can rapidly detect changes in bacterial growth to assess antibiotic susceptibility. Using a split ring microwave resonator, the device can very sensitively measure bacterial growth in the presence of different concentration (Read more...)

Breath Test Predicts Treatment Regimen for Epilepsy Drugs

Anti-seizure medication must be tailored for individual patients, as the difference between a therapeutic dose and a toxic one is quite small. Now, researchers at the University of Basel in Switzerland have developed a breath test that can rapidly provide information on the optimal drug treatment approach for epilepsy patients. Their test provides (Read more...)

Nanoparticles for Tumor Imaging and Cancer Urine Testing

Scientists at MIT have announced that they developed novel nanoparticles to detect cancer in urine samples. As well as detecting the presence of tumors, the nanoparticles can also accumulate at tumor sites and function as an imaging agent, helping to identify their location. These multifunctional particles could be very useful for routine cancer sc (Read more...)

DNA Origami to Trap Viruses Inside Body

Researchers at the Technical University of Munich have developed a method to create tiny virus traps that can bind viral particles and render them harmless within the body. The technique relies on DNA origami to create self-assembling hollow nanocapsules, which are lined with molecules that will bind viruses and prevent them from leaving. With a [& (Read more...)

Remote Monitoring for Peritoneal Dialysis: Interview with Aly ElBadry, CEO of CloudCath

CloudCath, a medtech company based in San Francisco, has created the CloudCath system, a remote monitoring technology that provides clinicians with data on the spent dialysate fluid of at-home peritoneal dialysis patients. CloudCath is incorporated into the drain line of peritoneal dialysis systems, and wirelessly transmits data to the cloud, with (Read more...)

Biomaterial-Based Vaccine Against Bacterial Infection

Researchers at the Harvard Wyss Institute have developed a biomaterial-based vaccine technology that could provide prophylactic protection against bacterial infection and septic shock. The technology is delivered as a biomaterial scaffold. Once inside the body, it captures bacterial pathogens and then recruits and activates dendritic cells to initi (Read more...)

Microchip Nanosensor Detects Stress Hormone from Drop of Blood

Researchers at Rutgers University have developed a microchip that can perform real-time measurements of stress hormone levels in a drop of blood. The technology could provide a replacement for bulky and expensive lab tests for such hormones, and allow patients to monitor their stress levels more easily. The chip includes tiny wells that contain ant (Read more...)

Blood-Brain Barrier on a Chip for Neuro Drug Testing

Researchers at the KTH Royal Institute of Technology in Stockholm, Sweden, engineered a blood-brain barrier on a chip using human-derived stem cells. The device closely mimics the blood-brain barrier and allows the researchers to study its function and the effect of drugs without having to use experimental animals. By incorporating sensors, the chi (Read more...)

Sweating E-Skin for Long-Term Health Monitoring

Researchers at MIT have developed an e-skin technology that contains artificial sweat ducts. The ducts prevent sweat accumulation underneath the e-skin, helping to prevent interference with built-in sensors. Incorporating a kirigami-style design, the material conforms to human skin but maintains a high porosity and reduced sweat accumulation. The d (Read more...)

Fluorescent mRNA to Track, Optimize Delivery

Researchers at Chalmers University of Technology in Sweden and collaborators created a technique to produce fluorescently labeled mRNA, allowing them to track its entry and distribution into cells. Using such molecules could help scientists develop better ways to deliver mRNA therapeutics into the body, potentially playing a vital role in the new w (Read more...)

Face Mask Detects SARS-CoV-2

Researchers at the Harvard Wyss Institute and MIT have developed a face mask that can detect SARS-CoV-2 in a wearer’s breath. The mask employs freeze dried molecular components including CRISPR-based technology, and a lateral flow assay strip to detect the virus and alert the wearer. To initiate the test, the wearer simply presses a button [& (Read more...)

Microarray Rapidly Identifies Antibodies Against SARS-CoV-2

Researchers at the Technical University of Munich in Germany have developed a sensitive and inexpensive microarray technology that can rapidly identify antibodies against the SARS-CoV-2 virus in blood or serum samples. The test can provide a result in as little as eight minutes, but the researchers believe that this can be further reduced to just [ (Read more...)
