20220233458 · 2022-07-28 ·

Green-synthesized tellurium nanowires (GREEN-TeNWs) are generated using a biopolymer as a unique reducing agent, purified, and used as a template for the growth of coated palladium nanoparticles (PdNPs) and platinum nanoparticles (PtNPs) on top of the GREEN-TeNWs, in a reaction that can take place in seconds, with no need for high temperature, stirring, or for additional reducing agent. The heterogeneous structure can contain palladium oxide or platinum oxide. The green-synthesized PdNPs-TeNWs (palladium nanoparticles with tellurium nanowires) and PtNPs-TeNWs (platinum nanoparticles with tellurium nanowires) show potential biomedical applications as antibacterial, anticancer, and antioxidant agents, and show low cytotoxicity for healthy human cells.
