implants like medical devices are often compromised by the host's foreign‐bodyresponse (FBR). Herein, we report the development of low‐FBR materialsinspired by serine‐rich sericin from silk. Poly‐β‐homoserine (β‐HS) materials consist of the hydrophilic unnatural amino acid β‐homoserine. Self‐assembled monolayers (SAMs) of β‐HS resist adsorption by diverse proteins, as well as adhesion by cells, platelets

Host-defense peptides inhibit bacterial growth but show little toxicity toward mammalian cells. A variety of synthetic polymers have been reported to mimic this antibacterial selectivity; however, achieving comparable selectivity for fungi is more difficult because these pathogens are eukaryotes. Here we report nylon-3 polymers based on a novel subunit that display potent antifungal activity (MIC = 3.1 mu g/mL for Candida albicans) and favorable selectivity (IC10 > 400 mu g/mL for 3T3 fibroblast toxicity; HC10 > 400 mu g/mL for hemolysis).
