Fluorescence Imaging: A Core Tool in Cell Biology

Fluorescence imaging technology is a core tool in cell biology research. With the development of CRISPR-based “turn-on” fluorescent probes enabling high-definition imaging of genomic DNA in living cells, high signal-to-noise ratio, low background, and real-time dynamic tracking have become the major trends in current fluorescence imaging. Meanwhile, significant progress has also been made in the field of organelle-targeting fluorescent probes. Professor Yu Yongliang’s team reviewed the important roles of fluorescent probes for lysosomes, mitochondria, and lipid droplets in dynamic monitoring of the microenvironment. As lipid droplets have become a hot topic in metabolic disease research, polarity-sensitive or near-infrared (NIR) fluorescent probes enable super-resolution imaging and real-time monitoring of pathological processes such as abnormal lipid metabolism and fatty liver disease, even offering a new approach for the early diagnosis of metabolic dysfunction-associated fatty liver disease (MAFLD).

Near-Infrared Imaging and Extracellular Vesicle Tracking

Near-infrared (NIR) fluorescence imaging technology, with its advantages of deep tissue penetration, high spatiotemporal resolution, and low background, has attracted considerable attention in live animal studies of tumors, blood vessels, and neuroscience. Innovative applications include NIR-II nanoprobes for high-resolution in vivo imaging. In addition, fluorescence labeling and tracking of extracellular vesicles (EVs) provide essential tools for elucidating their roles in intercellular communication and drug delivery. Dynamic fluorescence monitoring of autophagic flux and oxidative stress levels has also become a research hotspot in recent years. The development of new enzyme-activated and dual-response ratiometric probes offers robust technical support for dissecting the mechanisms of complex metabolic diseases such as non-alcoholic fatty liver disease (NAFLD).
