Real-time imaging of viscosity in the mitochondrial matrix by a red-emissive molecular rotor
Mitochondrial matrix contains numerous metabolism-related proteins/enzymes and nucleic acids, which play key roles in the process of energy generation and signal transduction. The fluctuations in mitochondrial biomacromolecular levels lead to the changes in the mitochondrial matrix viscosity; therefore, real-time measuring the mitochondrial matrix viscosity is of great significance for the in-depth understanding of the mitochondrial physiology and pathobiology. However, investigations are limited due to the lack of a mitochondrial matrix-specific molecular rotor. Herein, we report a design of a molecular rotor that is specifically enriched in the mitochondrial matrix. The red fluorescence of the rotor switches on when the viscosity increases, enabling the real-time monitoring of the viscosity change therein. Interestingly, the rotor showed non-fluorescence behaviour in the liposome (mimicking membrane structure), avoiding fluorescence interference from the mitochondrial bilayer membrane. Super-resolution imaging reveals that the viscosity is uneven in an individual mitochondrion.
