Open the CIPO recordAbstract From the Canadian patent
First activation radiation is provided to a sample that includes phototransformable , optical labels ("PTOLs") to activate a first subset of the PTOLs in the sample. First , excitation radiation is provided to the first subset of PTOLs in the sample to excite at least , some of the activated PTOLs and radiation emitted from activated and excited PTOLs , within the first subset of PTOLs is detecting with imaging optics. The first activation , radiation is controlled such that the mean volume per activated PTOLs in the first subset is , greater than or approximately equal to a diffraction-limited resolution volume ("DLRV") , of the imaging optics.
