Abstract

A stable, biocompatible, free-standing “paperlike” material composed of polyoxyethylene sorbitan laurate (TWEEN) and reduced graphene oxide platelets is presented. The TWEEN paper is highly stable in water (no leakage of TWEEN) and sufficiently robust to be handled by hand without breaking (see image). Furthermore, the material is noncytotoxic to three mammalian cell lines and inhibits nonspecific binding of Gram-positive bacteria.
