摘要: Abstract This work mainly focused on the relationship of microstructures, mesoporosity, and antibacterial properties silver/manganese oxide/bentonite (Ag/Mn3O4/bent) nanocomposite with without ionic liquid by thermal decomposition method. At room temperature aliphatic N-trimethyl-N-propylammonium bis(trifluoromethanesulfonyl)imide was used as capping agent for synthesis nanoparticles. The structural, morphological, elemental compositions optical pure nanocomposites were studied using XRD, XPS, BET, SEM, TEM SAED, EDX, FT-IR, UV-DRS techniques. X-ray diffraction result analyzed formation semi-crystalline nature nanocomposites. band gap values are smaller than that corresponding bulk materials due to quantum size effect estimated from study. SEM images showed well-defined quasi-spherical shape nanorod-like structures covered into interlayer surface bentonite clay. Their specific area, pore volume, determined BET method be ca. 90 m2 g− 1, two times higher pristine Na-bent. In vitro drug release sketch, cytocompatibility activities synthesized also investigated. against Gram-positive (Staphylococcus aureus) Gram-negative (Escherichia coli) bacteria. cytotoxicity effects examined in human embryonic kidney (HEK 293) cell line. Both results Ag/Mn3O4/bent/IL enhanced biocompatibility activity materials.
