Abstract
Methods of manufacturing produce metal implants having nano-modified surfaces that contain antimicrobial properties. The methods may include immersing the implant in an acid, rinsing the acid-treated implant in an aqueous cleaner, and thereafter heating the rinsed implant. The nano-modified implants described herein may contain an increased surface roughness; surface features with increased width or height; and/or decreased surface energy. The implants that result from these methods contain a nano-modified surface that is resistant to microbial cell adhesion and ultimately reduce biomaterials-related infections at the implant site.
