A team dedicated to designing energy conversion devices, led by Weilin Chen from Northeast Normal University in Changchun, recently designed a triboelectric nanogenerator based on changing the nanomorphology of polyoxometalates for gait monitoring of teenagers. Flexible, lightweight, and portable triboelectric nanogenerators are currently widely used in the field of wearable devices and have potential application value in gait monitoring. The nanogenerator designed by the team can sensitively capture abnormal gaits of teenagers, which can advance research in this field.

Researchers at NYU Abu Dhabi (NYUAD) have developed an innovative tool that enhances surgeons’ ability to detect and remove cancer cells during cryosurgery, a procedure that uses extreme cold to destroy tumors. This breakthrough technology involves a specialized nanoscale material that illuminates cancer cells under freezing conditions, making them easier to distinguish from healthy tissue and improving surgical precision.

During the first 72 hours in particular, extracellular vesicles—nanoparticles enclosed in cell membranes—play a significant role in the embryonic development of zebrafish.

For decades, scientists have relied on electrodes and dyes to track the electrical activity of living cells. Now, engineers at the University of California San Diego have discovered that quantum materials just a single atom thick can do the job—using only light.

A team of researchers at the George R. Brown School of Engineering and Computing at Rice University has developed an innovative artificial intelligence (AI)-enabled, low-cost device that will make flow cytometry—a technique used to analyze cells or particles in a fluid using a laser beam—affordable and accessible.
