Abstract

The living image: The efficient two-photon probes AZn1 and AZn2 (see picture for rat brain tissue) show 24-to 52-fold two-photon excited fluorescence enhancement in response to Zn2+. They can selectively detect intracellular free Zn2+ ions in live cells and in living tissues at a depth of 80-150 mm without interference from other metal ions and the membrane-bound probes.
