Adverse drug reactions (ADRs) restrict the maximum doses applicable in chemotherapy, which leads to failure cancer treatment. Various approaches, including nano-drug and prodrug strategies aimed at reducing ADRs, have been developed, but these their own pitfalls. A renovated strategy for ADR reduction is urgently needed. Here, we employ an enzymatic supramolecular self-assembly process accumulate a bioorthogonal decaging reaction trigger inside targeted cells, enabling spatiotemporally...
