Prof. Dong Zhenchao and Prof. Hou Jianguo from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) have improved the spatial resolution from 8 nm to ~8 Å of photoluminescence imaging. This has realized sub-molecular resolution with single molecule photofluorescence imaging for the first time.
