 This paper investigated the use of laser-induced breakdown spectroscopy, LIBS, to analyze the presence of graphene oxide and other elements on the surfaces of stainless steel 316 and titanium alloy T6L4V orthopedic threads. The authors found that the LIBS spectra of these materials differed significantly, with the graphene oxide exhibiting a distinct peak compared to the native material. Additionally, they were able to detect the presence of carbon atoms in the surface layer of the native material, indicating the incorporation of graphene oxide into the surface layer. Finally, a factor analysis confirmed this result, suggesting that graphene oxide had been successfully incorporated into the surface layer of the native material.
