Microneedle Bandage for Hemostatic Control

Scientists at Penn State have developed a microneedle bandage that can rapidly stop bleeding. Uncontrolled bleeding following a traumatic injury is a major cause of death in the young, and developing new medical technologies that can rapidly stop bleeding would be highly beneficial. This bandage contains an array of biodegradable and biocompatible microneedles made using […]

Flexible Sensors Detect Heavy Metals in Sweat

Researchers at the University of São Paulo in Brazil, along with collaborators in Germany and Sweden, have developed a flexible sensor that can detect heavy metals in sweat, an easily obtainable bodily fluid. Heavy metals, such as lead or cadmium, can cause serious toxicity if they accumulate in the body, but detecting the concentration of […]

Ultrasound Tornado Rapidly Disrupts Blood Clots

A team of researchers at North Carolina State University have developed an ultrasound transducer that can disrupt blood clots in the brain quickly by creating an ultrasound vortex or ‘tornado’. The transducer is designed to be housed in a catheter that can be advanced through the vasculature until it reaches the site of a blood […]

Nanopore Sensor to Study Protein Aggregation in Neurodegeneration

Researchers at the University of Arkansas have developed a nanopore sensor to study the aggregation of tau and tubulin protein molecules. These proteins, and specifically their aggregation in the brain, are implicated in neurodegenerative diseases such as Parkinson’s and Alzheimer’s. This nanopore technology aims to allow researchers to study the effects of different environmental conditions, […]

Smart Walking Stick for Visually Impaired People

Researchers at the University of Colorado at Boulder have developed a smart walking stick that can assist blind or visually impaired people to navigate their environment, from grocery shopping to finding a seat in a busy café. The system employs cameras to visualize the environment and items within it, such as products in a supermarket, […]
