Abstract

A two-photon probe (BCaM) shows 14fold enhancement in two-photon emission fluorescence in response to Ca²⁺ and shows high sensitivity and selectivity for near-membrane Ca²⁺ ions (see picture). Combined with the known Na⁺ twophoton probe ANa1, BCaM allows simultaneous dual-color imaging of Ca²⁺/Na⁺ activities within live cells and in tissues at more than 100 μm depth for long time periods without photobleaching. (Figure Presented)
