A novel fluorescence probe for simultaneous detection of mitochondrial viscosity in hepatic ischemia reperfusion injury models

A versatile probe with mitochondria targeting, PN, for detection of viscosity alteration in HIRI mouse model was fabricated. PN had high sensitivity and selectivity, and with a large Stokes shift (∼190 nm) for viscosity. PN is expected to be used for early diagnosis and treatment assessment of HIRI disease, and also provides diagnostic basis for other related diseases.
