Abstract: Antimicrobial peptides (AMP) have been extensively studied due to their rapid-acting, broad-spectrum activities and low possibility to develop resistance to bacteria. A potential approach to combating device-associated infections is to construct AMP-based antibacterial coatings on biomaterial surfaces. However, traditional AMP releasing coatings show temporary action due to the inherently limited reservoirs, while direct surface-tethering of AMP on surface usually suffers from the accumulation of dead microorganisms blocking functional groups. Considering the varied and complex applications of biomaterials, it is highly required to facilely adjust its functions in service and in antibacterial cases. A generic strategy by integrating the stimuli-responsive polymers and the existing antibacterial strategies exhibits a great potential in advancing the clinical applications of the AMP-based smart antibacterial platforms. In this review, the progress in the development of smart coatings based on AMP is reviewed. The main approaches to designing AMP releasing and non-releasing coatings are described, the roles of stimuli-responsive polymers in AMP-based smart coatings are also introduced, and the switching between its functions in service and antibacterial function is discussed. Furthermore, the future development of AMP-based smart coatings are prospected.
