摘要

Biomaterials have played an integral role in the field of modern medicine for many decades, serving various purposes such as acting as implants—whether internal or external, and whether designed for temporary or permanent use. They are also employed in drug delivery systems and as components in medical devices. As biomedical technologies have advanced, significant strides have been taken in the production of more advanced and secure biomaterials. These advancements have enhanced their compatibility with the human body, resulting in decreased negative impacts and an overall enhancement in the quality of life for those who use them. A biomaterial is a substance, whether it is naturally occurring or synthetic, that is utilised either in its entirety or as a component within the human body. Its primary purpose is to aid in the healing, augmentation, or replacement of tissues, organs, or specific bodily functions. The diversity of adverse reactions to biomaterials primarily hinges on the specific attributes of the material itself, including its antimicrobial features, as well as the response of the host tissue. Following the implantation of biomaterials, the immune response of host tissues is triggered by the interaction between foreign body giant cells and macrophages with synthetic surfaces. This response primarily comprises inflammatory and wound-healing processes. An additional concern after introducing a biomaterial into the body is the potential for opportunistic or pathogenic microorganisms to inhabit the material and the formation of biofilms on the surface of the implant. Consequently, enhancing the antimicrobial attributes through modifications to biomaterials stands as a pivotal factor in bolstering the long-term viability of implants. Diverse techniques to augment antimicrobial properties encompass antibiotic coatings, nanoparticle-based antimicrobial coatings, anti-fouling measures, surface charge adjustments and more.
