Graphene Edges Slice Cell Membranes – Is The Toxicity Of Nanomaterials A Cause For Concern?

Graphene1

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.

MOLECULAR ELECTRONICS

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.
