Antimicrobial synergy of cationic grafted poly(-phenylene ethynylene) and poly(-phenylene vinylene) compounds with UV or metal ions against .

The rise in multidrug resistant bacteria is an area of growing concern and it is essential to identify new biocidal agents. Cationic grafted compounds were investigated for their antimicrobial properties using minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) tests. Synergy testing was carried out using the compounds in the presence of ultraviolet (UV).
