Fluorescent probes for the selective detection of chemical species inside mitochondria

During the last few years, the preparation of novel fluorescent probes for the selective detection of chemical species inside mitochondria has attracted considerable attention because of their wide applications in chemistry, biology, and medical science. This feature article focuses on the recent advances in the design principles and recognition mechanisms of these kinds of fluorescent probes. In addition, their applications for the detection of reactive oxygen species (ROS), nitric oxide, reactive sulfur species (RSS), thioredoxin (Trx), metal ions, anions, etc. in the mitochondrion is discussed as well.
