Microrobots Roll Along Blood Vessel Walls to Deliver Drugs

Precise delivery of therapeutic drugs into diseased tissue remains a challenge in a variety of cases. Tumors can be hard to seed with chemo agents, particularly when the blood flow is not favorable for delivery. Now, researchers at the Max Planck Institute for Intelligent Systems in Germany have developed microscopic drug delivery devices that can (Read more...)

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...)

Automated Robot Takes Swabs for Safe Covid-19 Testing

Testing people for COVID-19 typically involves performing a throat swab to collect a sample for processing. Clinicians performing this task have to wear a complete package of personal protective equipment (PPE), something that can be very uncomfortable over long periods of time. Moreover, since sampling is now widely performed outside of a clinical (Read more...)

Planning for Future Pandemics Including Smallpox Outbreaks: Interview with Dr. Phil Gomez, CEO, SIGA Technologies

The COVID-19 pandemic has had significant global consequences, with healthcare systems stretched to their limits, a growing death toll, and economic devastation as economies came grinding to a halt. The pandemic and its aftereffects will be with us for some time to come, but this isn’t the first pandemic humanity has weathered, and it won&rsq (Read more...)

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...)

Paper Device Rapidly Measures Lithium Levels in Blood

Researchers at Hokkaido University in Japan have developed a paper-based point-of-care device which can measure lithium levels in a drop of blood. The device could help patients with bipolar disorder to keep track of their blood lithium levels. Lithium carbonate is used to treat bipolar disorder, but must be administered carefully as the concentrat (Read more...)

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 […]

Reusable Textiles to Repel Viruses

Researchers at the University of Pittsburgh have developed a coating that can be used to create textiles that repel viruses, along with bodily fluids such as saliva and blood. Interestingly, the coated textiles are reusable, and can be washed and scrubbed repeatedly without losing their virus-repelling properties. These characteristics may make 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 […]

Sensitive 10 Minute Antibody Test for SARS-CoV-2 Developed

A team of researchers at the Southern Medical University, Guangzhou, China, and collaborators report development of a rapid diagnostic assay for detection of SARS-CoV-2 antibodies in human blood. They report accurate detection with patient samples, with only 10 minutes to get a readout per blood sample. The new method is a lateral flow assay, much (Read more...)

Smart Contact Lenses Measure Glucose, Deliver Drugs

Researchers at the Pohang University of Science and Technology (POSTECH) report development of smart contact lenses for simultaneous glucose measurement and controlled drug delivery. The research, led by Professor Sei Kwang Han, found the contact lenses resulted in low irritation in rabbits, were able to reliably detect glucose levels in tears, and (Read more...)

3D Face Scans Accurately Screen for Sleep Apnea

Researchers at the University of Western Australia have demonstrated that facial features captured from 3D photographs may be useful as a screening tool for sleep apnea. 400 individuals participated in the study, and the researchers found that they could predict which patients would have sleep apnea with up to 91% accuracy. 300 individuals with sle (Read more...)
