Abstract
Antimicrobial cationic polycarbonates and polyurethanes have been prepared comprising one or more pendent guanidinium and/or isothiouronium groups. Additionally, antimicrobial particles were prepared having a silica core linked to surface groups comprising a guanidinium and/or isothiouronium group. The cationic polymers and cationic particles can be potent antimicrobial agents against Gram-negative microbes, Gram-positive microbes, and/or fungi.
