photophysical properties of ZBR4 and ZR1, two resorufin-based ditopic probes for mobile zinc. Upon binding Zn2+, the sensors display 14- and 41-fold enhancements of their red fluorescence emission, respectively. In contrast to ZR1 and other members of the ZBR family, which accumulate in the endoplasmic reticulum, ZBR4 spontaneously localizes to the mitochondria of HeLa cells. The modular approach in designing
