Light-guiding gels provide new avenues for drug detection, delivery

With the ability to deliver light inside the body in a predictable manner and to host a variety of genetically engineered cells, hydrogels may help address current challenges with applying optogenetic approaches in clinical care. Optogenetics is a relatively new technique that harnesses light to activate or inhibit light-responsive proteins that control specific cell functions.
