Graphical abstract
Mitochondria-targeted anticancer, antioxidant, and sensing agents can selectively accumulate in the mitochondria, where their modes of action occur. In most cases, lipophilic molecules intercalate into the mitochondrial membrane through lipophilic affinity and further move through the matrix owing to the membrane potential difference.
