Although nanoscopy can capture images of individual molecules inside cells, it is difficult to use with living cells because hundreds or thousands of imaging frames are needed to reconstruct an image -- a process too slow to capture quickly changing dynamics. > In Optica, The Optical Society's (OSA) journal for high impact research, investigators from the Chinese Academy of Sciences describe how they used the unconventional imaging approach known as ghost imaging to enhance the imaging speed of nanoscopy. The combination produces nanometer resolution using orders of magnitude fewer imaging frames than traditional nanoscopy techniques.
