A mitochondria-targeted far-red AIE fluorescent probe for distinguishing between mitophagy and ferroptosis in cancer cells

A mitochondria-targeted far-red fluorescent probe LY-1 with AIE character was formulated to track cell viscosity alterations with excellent sensitivity and selectivity, which was used to discriminate between mitophagy and ferroptosis in cancer cells. Probe LY-1 is expected to be an effective vehicle for the diagnosis of mitochondrial viscosity relevant diseases.
