Abstract On-demand synthesis of telluride nanostructure was developed from single-pass aerosol-based process under ambient gas flow conditions. Te nanoparticles(NPs) were assembled with Ag or Cu NPs using 4-Rod spark ablation system. Te NPs were partially alloyed with Ag or Cu NPs, resulting in 6 different formations of telluride nanocomposite. Then, their antimicrobial abilities were evaluated and compared with Ag, Cu and Te NPs. The minimal inhibitory concentration (MIC) values of the telluride nanocomposite against both Gram-positive bacteria (S.epidermidis) and Gram-negative bacteria (E.coli) were comparable to which of Ag or Cu NPs (that are famous as the antimicrobial agents) and their in vitro cytotoxicity was lower than which of Ag or Cu NPs as well. The simple on-demand doping process proposes a novel platform to constantly fabricate nanostructures which have safer antimicrobial activity without significant cytotoxic effects and environmentally friendly process.
