Organic fluorescent probes for live-cell super-resolution imaging

The development of super-resolution technology has made it possible to investigate the ultrastructure of intracellular organelles by fuorescence microscopy,which has greatly facilitated the development of life sciences and biomedicine.To realize super-resolution imaging of living cells,both advanced imaging systems and excellent fuorescent probes are required.Traditional fuorescent probes have good availability,but that is not the case for probes for live-cell super-resolution imaging.In this review,we frst introduce the principles of various super-resolution technologies and their probe requirements,then summarize the existing designs and delivery strategies of super-resolution probes for live-cell imaging,and fnally provide a brief conclusion and overview of the future.
