Far-field fluorescence microscopy at the macromolecular scale
Hell SW., Willig K., Hofmann M., Eggeling C., Westphal V.
Since its discovery by Abbe in 1873, the microscopy diffraction barrier has received a lot of attention. In this lecture, we discuss the principle of fundamentally breaking the diffraction barrier through reversible saturable optical (fluorescence) transitions (RESOLFT). © 2005 Optical Society of America.
