Bioactive coatings work by interacting with biological tissues to elicit specific responses, such as promoting cell adhesion, enhancing antimicrobial activity, or facilitating controlled drug release. When nanotechnology is employed, the nanoparticles can provide a higher surface area, improved mechanical properties, or better control over the release of bioactive agents. For example, silver nanoparticles are often used for their potent antimicrobial properties.
