Two photons are better than one: A two‐photon probe (ANa1, see picture) shows strong two‐photon fluorescence enhancement in response to Na+ and a dissociation constant (Kdi) of (26±2) mM in the cell. It can be easily loaded into the cells and can selectively detect intracellular free Na+ in live cells and living tissues at a depth of 100–200 μm for a long period of time.
