Photoresponsive polymers are special materials that change their properties when exposed to light. These polymers can undergo physical or chemical transformations, such as swelling, shrinking, or changing color, in response to specific wavelengths of light. This unique behavior makes them useful in various applications, including drug delivery systems and smart coatings. The ability of photoresponsive polymers to react to light allows for precise control over their functions. Researchers are exploring their potential in fields like biomedical engineering and optical devices, where they can be used to create responsive surfaces or to trigger specific actions in response to light stimuli.
