Abstract

Synthesis of polyionenes with built-in degradable linkers through addition polymerization of a novel class of degradable A-type monomers (d-A), and their use as antimicrobial agents are disclosed. A library of biodegradable polyionenes and Gemini-surfactants made from d-Amonomers are also disclosed. These materials have potent and broad spectrum of antimicrobial activity with high selectivity over mammalian cells.
