Researchers at University of Pittsburgh have discovered a new medicinal drug delivery system that precisely targets the bodily area affected. The system, based on graphene oxide, is triggered by an electrical charge and has been shown to release an anti-inflammatory drug on demand.
A graphene water balloon may soon open up new vistas for scientists seeking to understand health and disease at the most fundamental level.
Electron microscopes already provide amazingly clear images of samples just a few nanometers across. But if you want a good look at living tissue, look again.
A collaboration of biologists, engineers, and material scientists at Brown University has found that jagged edges of graphene can easily pierce cell membranes, allowing graphene to enter the cell and disrupt normal function. Understanding the mechanical forces of nanotoxicity should help engineers design safer materials at the nanoscale.
The latest research published by the RSC points to the potential for graphene to be used in wound care. Detailing the mechanism by which graphene slices through the membranes of bacteria and absorbs their phospholipids, the research throws extra light on a potential use that has been often cited. Graphene band-aids may well become a means of fighting infection, showing graphene to be a versatile material with multiple applications.
Electronic components built from single molecules using chemical synthesis could pave the way for smaller, faster and more green and sustainable electronic devices. Now for the first time, a transistor made from just one molecular monolayer has been made to work where it really counts; on a computer chip.
