Abstract

Antimicrobial resistance is becoming a global health concern; as such, the need for new effective treatments and preventive measures is increasing. Poly(para-phenylene ethynylene) (PPE)- and poly(para-phenylene vinylene) (PPV)-poly[(2-(methacryloyloxy)ethyl) trimethylammonium chloride] (PMETAC) graft copolymers were tested against a range of clinically and industrially relevant bacteria and results showed many of these conjugated polyelectrolytes (CPE’s) to be active. Of all of the compounds tested, PPE-g-PMETAC (low molecular weight, LMW) had greatest antimicrobial activity, especially against Enterococcus faecium, Methicillin resistant Staphylococcus aureus (MRSA), Escherichia coli and Acinetobacter baumannii.
