On the antibacterial mechanism of graphene oxide (GO) Langmuir-Blodgett films

14 January, 2015 - 10:54

Chem. Commun., 2015, Advance Article
DOI: 10.1039/C4CC07836E, CommunicationJ. D. Mangadlao, C. M. Santos, M. J. L. Felipe, A. C. C. de Leon, D. F. Rodrigues, R. C. Advincula
The Langmuir-Blodgett (LB) technique was used to immobilize flat graphene oxide (GO) sheets on a PET substrate to ascertain as to whether the edges of GO play an integral part in its antimicrobial mechanism. The observed antibacterial activity suggests that contact with the edges is not a fundamental part of the mechanism.
