Abstract
Advances in implantable technologies results from the rapid improvements in research in the fields of biomedical engineering, biomaterial science, and chemistry. No doubt, implantable technologies have provided greater comfort against several illnesses and diseases; however, pathogens adherence and biofilm formation are still the issues that need to be taken into consideration for further implant modifications. Pathogens colonize implants in a surface-dependent manner, so chances of pathogens' adhesion can be minimized by creating anti-adhesive and antimicrobial surfaces. The ongoing research is focused on the design of appropriate multifunctional coatings with a broad antimicrobial spectrum and high biocompatibility. Antimicrobial peptides in conjugation with polymers, nanoparticles, and other biocompatible agents can be potentially used to develop multifunctional coatings. Antibiotics-based coatings are the ultimate approach; however, optimizing the controlled release of antibiotics will be a breakthrough in this decade. Polymers unveil the extraordinary potential in implant coatings by increasing biocompatibility of coatings, offering the possibility for a triggered release of antimicrobial agents. An in-depth review of effective and biocompatible antimicrobial implant coatings is provided herein. We thoroughly discuss the remarkable antimicrobial agents and their compatibility with the host, including seemingly underexplored stability issues and providing an overlook on different methods of fabrication. The ever-growing materials research field can use this review's highlights to develop multifunctional implant coatings to reduce implant-associated infections.
