Nucleation and characterization of hydroxyapatite on thioglycolic acid-capped reduced graphene oxide/silver nanoparticles in simplified simulated body fluid

Hydroxyapatite formation initiated via Ca2+-adsorption upon complexation with COO− groups of thioglycolic acid (TGA) on the surfaces of reduced graphene oxide/silver nanoparticles (rGO/AgNPs) in simulated body fluid (SBF) and TGA chemisorbed on uniformly distributed AgNPs with a tilted geometric conformation through AgS bonds.
