      When activated by an enzyme, a synthesized cell-permeable probe forms biomolecule-anchored complexes and thus simultaneously evaluates the real-time location and bioactivity of the enzyme in single live cells. This simple and direct method can be used to monitor single-cell dynamic self-assembly processes in vitro and in vivo, which may provide new insights into previously undiscovered biological processes.
