A Precision‐Delivered Singlet Oxygen Generator With an Inbuilt Safety Switch for Induction of Pancreatic Beta Cell Stress and Death

Angewandte Chemie, EarlyView.
ROXendin668 is a peptidic GLP‐1 receptor agonist that generates toxic singlet oxygen upon irradiation with far‐red light. Pancreatic beta cells can be photo‐ablated in a spatiotemporally controlled manner. This approach has the potential to provide a safer alternative to streptozotocin or alloxan for creating model systems for type 1 diabetes research.
