Mark and destroy : Arsenic sulfide nanoclusters passivated by ethylenediamine derivatives can form a fluorescent, pH‐responsive nanosized colloidal hydrogel in water (see scheme). Besides acting as a fluorescent label, the arsenic sulfide nanogel exhibits remarkable cytotoxicity on certain cancer cells (OVCAR‐3 and HeLa).
