摘要
As an essential part in the toolbox of super-resolution microscopy,stimulated emission depletion(STED)nanoscopy has been widely explored in revealing the substructure and bioactivities in fluorescence imaging.Among the applied STED fluorophores,silicon-substituted rhodamines(SiRs)belong to one of the most extensively employed fluorophores.The carboxy-SiR was favored in STED bioimaging with many advantages,including reliable photostability,cell permeability,tunable fluorogenicity,feasible structural decoration and so on.We reviewed the research of carboxy-SiR in the STED nanoscopy and hopefully this can inspire more efforts in the design and application of STED fluorophores.
