Photoactivatable (alternatively, photoremovable, photoreleasable, or photocleavable)
protecting groups (PPGs), also known as caged or photocaged compounds, are used to …

More than four decades have passed since the first example of a light-activated (caged)
compound was described. In the intervening years, a large number of light-responsive …

Hydrogels are one of the most commonly explored classes of biomaterials. Their chemical
and structural versatility has enabled their use across a wide range of applications, including …

Polysaccharide‐based hydrogels have multiple advantages because of their inherent
biocompatibility, biodegradability, and non‐toxicic properties. The feasibility of using …

We report an aqueous and near‐infrared (NIR) light mediated photoinduced reversible
addition–fragmentation chain transfer (photo‐RAFT) polymerization system catalyzed by …

Organocobalt (III) complexes (R-CoIII), defined as cobalt complexes featuring a carbon–
cobalt bond, are largely used to produce carbon-centered radicals by homolytic cleavage of …

Light has emerged as a prominent stimulus to both generate and manipulate polymeric
materials across multiple length scales. Compared with other external stimuli, light-mediated …

Photoresponsive biomaterials are experiencing a transition from in vitro models to in vivo
demonstrations that point toward clinical translation. Dynamic hydrogels for cell …

Conspectus Light-responsive agents offer the promise of targeted therapy, whose benefits
include (i) prolonged action at the target site,(ii) overall reduced systemic dosage,(iii) …

In vivo, cells are located in a dynamic, three-dimensional (3D) cell microenvironment, and
various biomaterials have been used to engineer 3D cell microenvironments in vitro to study …
