In recent years, the environment sensitive hydrogel had attracted extensive interest for their application to the biomedical areas such as drug deliverers. The hydrogel was able to undergo large chain conformational changes with respond to stimuli such as temperature, pH, light, electric signal, pressure. As a result, a number of stimuli-responsive smart materials have been developed and extensively investigated. Among these materials, the photo-responsive materials containing photochromic compounds such as azobenzene, stilbene, and spiropyran have been widely studied over the past couple of decades because of their unique optical properties. In this study, we report on new photo-cured hydrogel containing stimuli-responsive smart materials such as azobenzene. In addition, we investigated the compositional effects of drugs on the photomechanical properties of these smart hydrogels. When the smart hydrogel was irradiated with UV, Drug emission was controlled by the light. |
