Abstract
Techniques and devices including a biocompatible antibacterial film are provided. An example method for depositing a biocompatible antibacterial film using physical vapor deposition (PVD) includes providing a substrate in a PVD processing chamber, forming a deposited film by co-depositing a first material and a second material onto the substrate from a vapor plume, wherein at least the first material is biocompatible and at least the second material is antibacterial, and nano-texturing the deposited film to produce nano-scale surface asperities that provide at least one of inhibition of bacterial growth, promotion of osseointegration, promotion of epithelial attachment, or promotion of endothelial attachment.
