We report the visualization of NO production using fluorescence in tissue slices of the mouse main olfactory bulb. This discovery was possible through the use of a novel, cell-trappable probe for intracellular nitric oxide detection based on a symmetric scaffold with two NO-reactive sites. Ester moieties installed onto the fluorescent probe are cleaved by intracellular esterases to yield the corresponding negatively charged, cell-impermeable acids. The trappable probe Cu[subscript 2](FL2E) and the membrane-impermeable acid derivative Cu[subscript 2](FL2A) respond rapidly and selectively to NO in buffers that simulate biological conditions, and application of Cu[subscript 2](FL2E) leads to detection of endogenously produced NO in cell cultures and olfactory bulb brain slices.
