GSD microscopy
Ground state depletion microscopy (GSD microscopy) is an implementation of the RESOLFT concept. The method was proposed in 1995[1] and experimentally demonstrated in 2007.[2] It is the second concept to overcome the diffraction barrier in far-field optical microscopy published by Stefan Hell. Using nitrogen-vacancy centers in diamonds a resolution of up to 7.8 nm was achieved in 2009.[3] This is far below the diffraction limit (~200 nm).
