report mtDNA imaging with a chameleon sensor containing a cationic rhodamine B (RB) entity for mitochondria targeting and a fluorogenic SYBR Green-I (SG) entity for DNA sensing. SG-RB selectively binds to mtDNA and gives green SG fluorescence in mitochondria of living cells but gives red RB fluorescence upon delivery of mitochondria into lysosomes in mitophagy. With the dual-color imaging, mtDNA aggregation

[reaction: see text] An efficient method for the synthesis of functionalized rhodamine derivatives has been developed. Multigram quantities of these water-soluble fluorophores can be prepared from inexpensive precursors and purified without the use of chromatography. A series of protein-reactive functional groups has been installed through subsequent reactions, providing materials for biomolecule modification
