The uses of implantable medical devices are safer and more common since sterilization methods and techniques were established a century ago; however, device-associated infections (DAIs) are still frequent and becoming a leading complication as the number of medical device implantations keeps increasing. This urges the world to develop instructive prevention and treatment strategies for DAIs, producing a publication boom on the design of antibacterial surfaces for implantable medical devices. To help identify the flaws of our current antibacterial designs and advance their clinical translations, the clinical features of DAIs are recently highlighted by Huiliang Cao et al [1].
using magnetron sputtering synthesized nanosilver coatings for wound care [22], MUTARS prosthesis reducing infections by electroplating a metallic-silver surface, METS prosthesis acting against pathogenic bacteria by absorption of ionic silver to anodized titanium implants [23], PorAg prosthesis taking advantage of a controlled electrochemical reaction (do not directly release silver ions) in a titanium-silver alloy for disinfection [23], and PROtect nails administrating gentamicin for prevention of infections in complex open fractures [24]. These commercial promotions have set examples for the development of antibacterial surfaces for implantable medical devices; however, it is still a challenge to improve the quality and efficiency of translational research over those “antibacterial surface” or “antibacterial coating” reports.

Please Note: This entry Extracellular electron transfer is a partgeneral mechanism required for bacterial growth [159][160][161][162]. The microbial cell envelope is not electrically conductive; hence bacteria have evolved strategies to exchange electrons with extracellular substances [163], including direct electron transfer via physical contacts (through the bacterial envelope or pili) between a microbe and a material surface, and redox-active compounds mediating electron shuttle between bacteria and the material’s surface serve as electron acceptors [164].
