Malar Azagarsamy, Dan McKinnon, and Danny Alge publish "Coumarin-Based Photodegradable Hydrogel: Design, Synthesis, Gelation, and Degradation Kinetics" in ACS Macro Letters
,Ìý, and  show the gelation and degradation kinetics of a polymer network using coumarin as a new class of photodegradable crosslink. Micron-scale erosion was performed at wavelengths as long as 860 nm. Find the paper .
