Recent progress in two-photon small molecule fluorescent probes for enzymes

Enzymes are macromolecular biological catalysts which can accelerate chemical reactions in living organisms. Almost all the physiological metabolism activities in the cell need enzymes to sustain life via rapid catalysis. Currently, medical research has proved that abnormal enzyme activity is associated with numerous diseases, such as Parkinson’s disease (PD), Alzheimer's disease (AD) and cancers. On the other hand, early diagnosis of those...
