Soft skin patch could provide early warning for strokes, heart attacks

UC San Diego engineers developed a soft, stretchy ultrasound patch that can be worn on the skin to monitor blood flow through vessels deep inside the body. Such a device can make it easier to detect cardiovascular problems, like blockages in the arteries that could lead to strokes or heart attacks. Full Story

Bio-inspired hydrogel protects the heart from post-op adhesions

A hydrogel that forms a barrier to keep heart tissue from adhering to surrounding tissue after surgery was developed and successfully tested in rodents by a team of University of California San Diego researchers. The team of engineers, scientists and physicians also conducted a pilot study on porcine hearts, with promising results. They describe their work in the June 18, 2021 issue of Nature Communications.   Full Story

Genetically engineered nanoparticle delivers dexamethasone directly to inflamed lungs

Nanoengineers at the University of California San Diego have developed immune cell-mimicking nanoparticles that target inflammation in the lungs and deliver drugs directly where they’re needed. As a proof of concept, the researchers filled the nanoparticles with the drug dexamethasone and administered them to mice with inflamed lung tissue.  Full Story

Stabilizing gassy electrolytes could make ultra-low temperature batteries safer

A new technology could dramatically improve the safety and performance of lithium-ion batteries that operate with gas electrolytes at ultra-low temperatures. By keeping electrolytes from vaporizing, the technology can prevent pressure buildup inside the battery that leads to swelling and explosions. Full Story
