light responsive hydrogels
Also known as: light-responsive hydrogels
Taxonomy: Mechanism Branch / Architecture. Workflows sit above the mechanism and technique branches rather than replacing them.
Summary
Thus, light responsive hydrogels are of particular interests to researchers in developing accurate and controlled drug delivery systems. Light responsive hydrogels are obtained by incorporating photosensitive moieties into their polymeric structures.

They require a hydrogel polymer structure plus incorporated photosensitive moieties, and operation depends on an appropriate light source. Some systems also incorporate photosensitizers to respond to specific wavelength ranges.; requires incorporation of photosensitive moieties into polymeric structures; clinical use may require matching the system to ultraviolet, near-infrared, or up-conversion-enabled light activation
The abstract does not claim that light-responsive hydrogels automatically solve targeting, metabolism, or toxicity challenges. Instead, it states that these principles must be used to optimize efficacy and safety.; clinical optimization must consider site-specific targeting, metabolism, and toxicity
