Phyto-mediated synthesis of Ag nanoparticles/attapulgite nanocomposites using olive leaf extract: Characterization, antibacterial activities and cytotoxicity

•Ag NPs/APT nanocomposites were synthesized by olive leaf extract mediated method.•APT nanorods provide active sites to controllable size and dispersion of Ag NPs.•Nanocomposites loading with 5% Ag NPs shows good antibacterial performance.•Nanocomposites almost has no cytotoxicity in vitro to mouse fibroblasts L-929.
