Abstract

Two types of small photoblinking Pdots with high brightness, strong photostability, and favorable biocompatibility, are designed. Super-resolution optical fluctuation imaging is achieved using these Pdots. Imaging of subcellular structures demonstrates that these small photoblinking Pdots are outstanding probes for fast, long-term super-resolution fluorescence imaging.
