Recent advances in bioorthogonal catalysis are increasing our capacity to manipulate the fate of molecules in complex biological systems. Herein we report a novel bioorthogonal uncaging strategy that is triggered by heterogeneous gold catalysis andfacilitates the activation of a structurally-diverse range of therapeutics in cancer cell culture. Furthermore, this solid supported catalytic system enabled —for the first time— the locally-controlled release of a fluorescent dye in the brain of a zebrafish, offering a novel way to modulate the activity of bioorthogonal reagents in the most fragile and complex organs.
