This review aims to summarize the current status of photoactivatable nanostructured film and polymeric nanofiber surfaces used in biomedical applications with emphasis on their photoantimicrobial activity, oxygen-sensing in biological media, light-triggered release of drugs, and physical or structural transformations. Many light-responsive functions have been considered as novel ways to alter surfaces, i.e., in terms of their reactivities and structures. We describe the design of surfaces, nano/micro-fabrication, the properties affected by light, and the application principles. Additionally, we compare the various approaches reported in the literature.
