(A) Principle of imaging enzyme-triggered supramolecular self-assembly inside cells. (B) Molecular structure of the precursor 16 and the corresponding hydrogelator 17. (C) Fluorescent confocal microscope images show the time course of fluorescence emission inside the HeLa cells incubated with 500 μM of 16 in PBS buffer, which shows the different distribution of fluorophores inside the living cells. Scale bar is 50 μm. Adapted with permission from ref. 31. Copyright 2012, Nature Publishing Group.
