MitoPY1 is a targetable fluorescent probe for imaging hydrogen peroxide (H2O2) in mitochondria of living cells, which displays enhanced emission at 528 nm in the presence of H2O2.

MitoPY1 has been used as a specific mitochondrial H₂O₂ probe to measure mitochondrial ROS (reactive oxygen species) level.

MiroPY1 is an irreversible and bifunctional dye. It employs a triphenylphosphonium targeting group and a boronate-based molecular switch to specifically respond to H2O2 over competing reactive oxygen species (ROS) in the mitochondria. It does not require transfection. MiroPY1 is photostable and limits false positives.
