The invention provides fluorescent sensors for the selective detection of a metal such as copper. The sensors may be considered to be derivatives of cyanine, fluorescein, rhodamine, rhodol, Tokyo green, or BODIPY. The sensors find particular use in detecting copper in cells and living animals.

human health. Seeking a suitable detection method to monitor sulfur dioxide in real time becomes an urgent requirement owing to the transient nature of sulfur dioxide in organisms. Here, a novel NIR ratiometricfluorescentprobe for detection of SO2 was developed based on a conjugation of coumarin and indol salt with excellent water solubility. The probe Mito-CI displayed highly sensitive (69 nM), fast
