New sensor is six orders of magnitude more sensitive than any electrochemical sensor for the deadly drug

Synthetic opioids are one of the main drivers in overdose deaths in the United States. They are often mixed with other drugs, but because of their potency, they are often present in such small amounts that they can be hard to detect. The new sensor, developed by researchers at the University of Pittsburgh, uses carbon nanotubes and gold nanoparticles to tell the most deadly drugs apart from others.

Scientists successfully 3D-print human skin tissue into open wounds

By /

Scientists at Pennsylvania State University have successfully 3D-printed living human skin tissue directly into the open wounds of rats for the first time in history. This bioengineering milestone could pave the way for major developments in reconstructive surgery — or even human hair treatments. Current methods of skin and hair reconstruction — like skin grafts — often result in scars, meaning this discovery could lead to a more seamless treatment for humans.
