“…The addition of Ag enhanced the antimicrobial efficacy against both microorganisms due to Ag ions released from the coating. Similar antimicrobial effect vs E. coli and S. aureus was found by testing porous TiO 2 coatings on Ti surfaces containing different Ag concentrations (ranging from 0% to 15%) . The same research group in a further study reported the activity of these Ag‐TiO 2 coatings for long term (28 days) .…”

The use of implantable medical devices is a common and indispensable part of medical care for both diagnostic and therapeutic purposes. However, as side effect, the implant of medical devices quite often leads to the occurrence of difficult‐to‐treat infections, as a consequence of the colonization of their abiotic surfaces by biofilm‐growing microorganisms increasingly resistant to antimicrobial therapies. A promising strategy to combat device‐related infections is based on anti‐infective biomaterials that either repel microbes, so they cannot attach to the device surfaces, or kill them in the surrounding areas. In general, such biomaterials are characterized by antifouling coatings, exhibiting low adhesion or even repellent properties towards microorganisms, or antimicrobial coatings, able to kill microbes approaching the surface. In this light, the present overview will address the development in the last two decades of antifouling and antimicrobial biomaterials designed to potentially limit the initial stages of microbial adhesion, as well as the microbial growth and biofilm formation on medical device surfaces.

“…This method is based on anodic oxidation of metal in an electrolyte, at voltages that lead to plasma micro-discharges at the electrode surface [6][7][8] . In general, MAO coatings fabricated on Ti alloys are composed of anatase and rutile titanium oxide (TiO 2 ), and the coatings obtained from aluminate-containing electrolytes also contain aluminum titanate (Al 2 TiO 5 ) [4,[9][10][11][12] . The high hardness of such coatings leads to high wear resistance, however, exhibits relatively low wear resistance and high friction coefficients under non-lubrication conditions.…”

“…In a similar study, Shin et al have found no cytotoxic response at low AgNPs concentration (0,0.1 g/l) in (MC3T3‐E1) cell line, but increasing concentration (0.3 and 0.5 g/L) had a negative impact on cell proliferation . Zhang et al analyzed cytotoxicity behavior of PEO TiO 2 layer using the mouse preosteoblast cells on sputtering‐deposited AgTi surface with Ag content varying 0, 0.95, 1.36, and 1.93 wt %. PEO surfaces with Ag content 1.36 wt % and above were reported to be cytotoxic …”

Plasma electrolytic oxidation (PEO) is an advance technique to develop porous oxidation layer on light metals, primarily to enhance corrosion and wear resistance. The oxidation layer can also offer a wide variety of mechanical, biomedical, tribological, and antibacterial properties through the incorporation of several ions and particles. Due to the increasing need of antimicrobial surfaces for biomedical implants, antibacterial PEO coatings have been developed through the incorporation of antibacterial agents. Metallic nanoparticles that have been employed most widely as antibacterial agents are reported to demonstrate serious health and environmental threats. To overcome the current limitations of these coatings, there is a significant need to develop antibacterial surfaces that are not harmful for patient's health and environment. Attention of the readers has been directed to utilize bioactive glasses as antibacterial agents for PEO coatings. Bioactive glasses are well known for their excellent bioactivity, biocompatibility, and antibacterial character. PEO coatings incorporated with bioactive glasses can provide environment-friendly antimicrobial surfaces with exceptional bioactivity, biocompatibility, and osseointegration. © 2017 Wiley Periodicals, Inc.
