Aerosol-assisted plasma deposition of hydrophobic polycations makes surfaces highly antimicrobial

Appl Biochem Biotechnol. 2014 Feb;172(3):1254-64. doi: 10.1007/s12010-013-0593-4. Epub 2013 Oct 26.

Abstract

The currently used multistep chemical synthesis for making surfaces antimicrobial by attaching to them hydrophobic polycations is replaced herein by an aerosol-assisted plasma deposition procedure. To this end, N,N-hexyl,methyl-PEI (HMPEI) is directly plasma-coated onto a glass surface. The resultant immobilized HMPEI coating has been thoroughly characterized and shown to be robust, bactericidal against Escherichia coli, and virucidal against human influenza virus.
