“…Magnesium and magnesium alloys are a "green engineering material" in the 21st century, having a wide range of application prospects, such as automotive, in aerospace, portable electronic devices, and in medicine. This is due to their superior strength-weight ratio, dimensional stability, light weight, recycling ability, and other excellent properties [1,2]. However, the corrosion resistance of magnesium and magnesium alloys is extremely poor, severely restricting their further development [3,4].…”

Many surface treatment methods are used to improve the corrosion resistance of magnesium alloys. LDH (layered double hydroxides) conversion coatings are currently found in the most environmentally friendly and pollution-free coatings of magnesium alloy. In this study, the CO2 pressurization method was applied to the preparation of LDH coating on magnesium alloy for the first time. The effect of CO2 pressurization on the formation and corrosion resistance of LDH coating on AZ91D alloy was investigated. The hardness and adhesion were significantly higher on LDH coating in the case of CO2 pressurization than it is in atmospheric pressure. The surface and cross-sectional morphologies show that LDH coating is more compact in the case of CO2 pressurization than with atmospheric pressure. The results of the polarization curve, hydrogen evolution, and immersion tests indicate that the corrosion resistance of the LDH coating prepared by the CO2 pressurization method was significantly improved.

Rapid emergence of antibiotic resistance facilitates the development of a number of novel‐acting alternatives. Among these emerging approaches, metal oxide nanoparticles receive great attention due to their distinctive performance in antimicrobial stewardship. These nanoparticles can not only target the cell wall, membrane, and cytoplasmic contents to disrupt cellular homeostasis, but can also generate reactive oxygen species highly cytotoxic for virtually all microorganisms without resistance concern. By taking advantage of inherent imaging characteristics and facile surface functionalization with specific imaging moieties, the metal oxide nanoparticles show great promise in the bacterial tracing and eradicating. In this review, we examine a critical analysis of antimicrobial mechanisms, physicochemical characteristics, and modification strategies for metal oxide nanoparticles. The diagnosis of metal oxide nanoparticles for bacterial infections, coupled with their potential for bacterial theranostics, has been highlighted. We anticipate that this review will provide new insights on design and development of advanced metal oxide nanoparticles to manage bacterial infections, particularly those caused by multidrug‐resistant species.

“…The bactericidal activity of these ions seems to depend on their gradual release from specimens into surrounding tissues. In the study of Zhao et al, silver nanoparticles (AgNPs) and polymethyltrimeth-oxysilane (PMTMS) were introduced into AZ31 Mg alloys via layer-by-layer (LbL) assembly and a siloxane self-condensation reaction [66]. Yang et al introduced copper-bearing bioactive glass nanoparticles into polycaprolactone coating systems to improve the bioactivity, antibacterial property, and corrosion resistance of magnesium matrices and thoroughly compared different amounts of Cu-BGNs (1, 3, and 5 wt.%) in PCL coatings in their study [67].…”

As a revolutionary implant material, magnesium and its alloys have many exciting performances, such as biodegradability, mechanical compatibility, and excellent biosecurity. However, the rapid and uncontrollable degradation rate of magnesium greatly hampers its clinical use. Many efforts have been taken to enhance the corrosion resistance of magnesium. However, it must be noted that improving the corrosion resistance of magnesium will lead to the compromise of its antibacterial abilities, which are attribute and proportional to the alkaline pH during its degradation. Providing antibacterial functionalized coating is one of the best methods for balancing the degradation rate and the antibacterial ability of magnesium. Antibacterial functionalized magnesium is especially well-suited for patients with diabetes and infected wounds. Considering the extremely complex biological environment in the human body and the demands of enhancing corrosion resistance, biocompatibility, osteogenesis, and antibacterial ability, composite coatings with combined properties of different materials may be promising. The aim of this review isto collect and compare recent studies on antibacterial functionalized coatings on magnesium and its alloys. The clinical applications of antibacterial functionalized coatings and their material characteristics, antibacterial abilities, in vitro cytocompatibility, and corrosion resistance are also discussed in detail.
