Click reactions on polymer surfaces lead to antimicrobial behaviour

Friday, 4 April 2014

Researchers developed simple reactions that combined microwave plasma reactions in the presence of maleic anhydride with alkyne click chemistries.

The goal was to achieve a platform for unlimited possibilities for further surface modifications of aliphatic polymer surfaces.

Decrease of bacterial growth was achieved

Using this approach, Heather A. Pearson and Marek W. Urban from Center for Optical Materials Sciences and Engineering Technologies (COMSET), Clemson University, USA, covalently attached ampicillin (AMP) to polyethylene (PE) and polypropylene (PP) substrates. As a result, high efficacy against microbial film formation, manifested by efficient antimicrobial activity against S. aureus with a 97-99.8% decrease of bacterial growth, was achieved. This simple and clean process allows functionalization of any polymeric substrate without adverse effects on bulk polymer properties.

The study has been published in: Journal of Materials Chemistry B, Issue 15, 2014
