Abstract
Silver nanoparticles (AgNPs) based antibacterial materials are widely applied to commodity and clinic wound treatments. However, genotoxicity and inflammatory response induced by AgNPs inhibit their application as the antibacterial coating of medical devices like catheters. A novel gelatin-AgNPs coating manufacture method was introduced here to generate an antibacterial coating, which nearly immunes to inflammatory, on basal PHBV material. The novel gelatin-AgNPs coating was produced by immobilizing gelatin on the Poly (3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) membrane and subsequently fixing AgNPs on acquired gelatin coating. Prepared gelatin-AgNPs coatings displayed considerable antibacterial capacity. These gelatin-AgNPs coatings did not cause inflammation, growth inhibition or apoptosis to normal human embryonic lung fibroblasts, MRC-5 cells, by analyzing the transcription levels of relevant genes in these cells incubated with tested coatings for 4Â days. Hence, this novel gelatin-AgNPs coating manufacture method paved its way to apply in medical devices manufacture including catheters.
