Abstract
This report involves the production of Au/Ag core-shell nanoparticles that were incorporated into cubic aluminum zeolite ([Al]-ZSM-5) and their test towards the microbial activity. The produced nanocomposite was characterized by X-ray diffractometry (XRD) and high transmission electron microscopy (HRTEM). The formation of Au/Ag core-shell with particle size in the range of 10-13 nm has been confirmed by HRTEM. The antibacterial activities of the samples were studied for different Gram-positive and Gram-negative bacteria. Zeolite, with its well-defined structure and microporous cavities, functions well for core-shell nanoparticle hosting. The demonstrated antimicrobial activity of the fabricated nanocomposite renders them potentially useful as antibacterial masks.
