• Silk fibroin@Ag spheres were prepared by in situ deposition of Ag nanoparticles on silk fibroin spheres. • Silk fibroin@Ag spheres were not cytotoxic and biocompatible. • Silk fibroin@Ag spheres showed antibacterial activity against the growth of bacteria. In this study, novel silk fibroin@Ag spheres were synthesized by in situ growth of Ag nanoparticles (NPs) on silk fibroin (SF) spheres and their microstructure, in vitro biocompatibility, and antibacterial property were evaluated. SEM observation showed that SF@Ag spheres had a spherical morphology with a diameter of 1–10 µm. TEM observation revealed that each SF@Ag sphere had a dense structure and its surface was deposited with Ag NPs with a diameter of 10–50 nm. In vitro biocompatibility evaluation indicated that SF@Ag spheres were not cytotoxic when incubated with osteoblast MC3T3-E1 cells. Moreover, when exposed to two representative types of gram-negative Escherichia coli and gram-positive Staphylococcus aureus , SF@Ag spheres showed a good antibacterial property against the growth of both types of bacteria.
