LbL coating has also been employed to modify inorganic surfaces. Although many applications for these surface modifications are possible, only some antimicrobial examples are mentioned. Stainless steel surfaces were primed with an acrylate-based surfactant via electrografting. Subsequently, PSS and PDDA layers were coated in an alternating fashion. Lastly, a layer of chitosan was coated as an antibacterial layer against E. coli and S. aureus [82]. Silicone-based intraocular lenses (IOL) are commonly employed to replace the natural eye lens when it is damaged. The IOL can, however, allow adhesion of many kinds of bacteria and lead to post-operative infections with catastrophic effects in some patients. LbL nanocoating of the lenses with hyaluronic and chitosan had significant anti-adhesion and bactericidal effects that reduced the risk of postoperative infections [83,84].
