Abstract
Poly(β-peptoid)s selected from the group consisting of poly(N-methyl-β-alanine)s (PMeA) and poly(N-ethyl-β-alanine)s (PEtA) and polyl(methyl-β-alanine-co-ethyl-β-alanine) copolymers (P(MeA-co-EtA) are found to be good anti-fouling materials in that they resist protein adsorption. A process for protecting a surface of an object from protein adsorption comprises the steps of binding such poly(β-peptoid)s to the surface. A medical implant is coated with such poly(β-peptoid)s. A medical drug delivery device is coated with such poly(β-peptoid)s. A filtration device has pores coated with such poly(β-peptoid)s, and an object placed in freshwater or saltwater and having a surface in contact with the freshwater or saltwater has that surface coated with such poly(β-peptoid)s.
