제목 In Vitro Assessment of Antibacterial Properties and Cytotoxicity of Silver-containing PLGA Nanofibrous Scaffolds
초록 Infections with bacteria have become a serious problem in joint arthroplasty. This study reports on in vitro antibacterial activity and in vitro cytotoxicity of PLGA nanofibers loaded with silver nanoparticles (520nm). In vitro antibacterial activity against Staphylococcus aureus and Klebsiella pneumoniae was studied by microplate proliferation tests. The adhesion, viability and proliferation properties of fibroblasts and osteoblasts were done to study in vitro cytotoxicity. Only silver-containing PLGA nanofibrous scaffolds showed high-antibacterial activity and an inhibitory effect on the growth of Staphylococcus aureus and Klebsiella pneumoniae. There was no significant difference regarding in vitro cytotoxicty between silver-containing and non-containing PLGA scaffolds. It was found, from in vitro experiments, that the silver-containing PLGA nanofibrous scaffolds have a potential to be used in joint arthroplasty.
