Surface modifications are frequently applied to enhance the multifunctional performance of metallic materials in biomedical applications, and nanotechnology has the advantage of enabling the development of highly customized surface functions and properties. However, the surface of 316L stainless steel (SS316L) exhibits bioinert behavior with tissues, can be easily corroded by body fluids due to the containing Cl ions, and leads to bacterial attachment. This study aimed to improve the multifunctional properties of SS316L by coating it with a novel matcha/polyethylene glycol-CuO NPs (Mat/PEG-CuO NPs) synthesized by a simple ultrasound-assisted method. The phyto/sonosynthesized CuO NPs were characterized by a range of advanced techniques, and their coating on the surface of SS316L was analyzed for electrochemical corrosion and antibacterial behavior. The experimental results showed that the spherical-shaped CuO NPs were successfully fabricated and coated onto SS316L to improve its surface characteristics. The coating with CuO NPs, having an average thickness of 5.31 & mu;m, demonstrated exceptional anti-corrosive and anti-bacterial characteristics, showing a zone of inhibition measuring 29.5 mm and 25.5 mm against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus), respectively. The results demonstrate the successful fabrication of spherical CuO NPs coated onto SS316L, which holds great promise for biomedical applications.
