Fabrication of a silver octahedral nanoparticle-containing polycaprolactone nanocomposite for antibacterial bone scaffolds†
Abstract
This work investigated the antimicrobial activity of Ag octahedral nanoparticle containing polycaprolactone scaffolds (Ag–PCL) that is fabricated via cryomilling. The fabricated composite scaffolds exhibited localized antibacterial activity with no adverse effects on viability and osteogenic differentiation of human fetal mesenchymal stem cells (hfMSCs). Compared to plain PCL scaffolds, the Ag–PCL scaffolds significantly reduce bacteria survival to 32.2% over a 4 hour incubation.
