BIOMEDICAL IMPLANT SYSTEM

Abstract: a biomedical implant system includes a substrate and a coating. the coating includes a first layer including titanium dioxide nanotubes and a second layer including a polyvinylidene fluoride polymer. the titanium dioxide nanotubes extend perpendicularly from a surface of the substrate and contain ciprofloxacin. the titanium dioxide nanotubes are capped on an outer end with the polyvinylidene fluoride polymer. a process for making the biomedical implant system includes anodizing the substrate, at a voltage of 20 v to 80 v for a time of 10 to 200 minutes, in a solution to form the first layer of the coating. the first layer of the coating is further dried, annealed, loaded with ciprofloxacin, and covered with the second layer of the coating.
