Green Synthesis of Ag and Cu Nanoparticles Using Ehrh Extract: Coating, Characterization, and Bioactivity on PEEK Polymer Substrates.

PEEK-based implant materials have gained increasing attention as an alternative to titanium due to their biocompatibility and bone-like elasticity. However, PEEK's surface quality and wear resistance are lower than those of metals. This study aimed to enhance the bioactivity and surface quality of PEEK by coating it with silver and copper nanoparticles synthesized via a green method using Ehrh.
