Indeed, within the world of super resolution microscopy, PA - FPs have helped create several new imaging methods, including photoactivation -
localization microscopy (PALM, also FPALM)(11).
Furthermore, the microscope will be capable of performing live - cell super-resolution imaging through structured illumination microscopy (SIM) and Super-Resolution Radial Fluctuations (SRRF); for fixed cells resolutions on the scale of tens of nanometres will be achievable using single molecule
localization microscopy (SMLM) techniques.

localization microscopy.
By tracking a limited ensemble of diffusible molecules over time, the spatiotemporal dynamics of molecules and the connectivity within microcompartments can be obtained in addition to superresolved (tracking and
localization microscopy, TALM).
We will use high and super-resolution fluorescence microscopy like total internal reflection fluorescence microscopy (TIRFM) and fluorescence photo - activation
localization microscopy (FPALM) to visualize and track the spatio - temporal dynamics of tethering and SNARE proteins in live and fixed cells with single molecule resolution.
We demonstrated the technique on 20 different biological processes spanning four orders of magnitude in space and time, including the binding kinetics of single Sox2 transcription factor molecules, 3D superresolution photoactivated
localization microscopy of nuclear lamins, dynamic organelle rearrangements and 3D tracking of microtubule plus ends during mitosis, neutrophil motility in a collagen mesh, and subcellular protein localization and dynamics during embryogenesis in Caenorhabditis elegans and Drosophila melanogaster.
But he notes that SIM has always offered two advantages over alternative super-resolution methods, including photoactivated
localization microscopy (PALM), which he developed in 2006 with Janelia colleague Harald Hess.
The new technique, dubbed photoactivated
localization microscopy, currently has a resolution similar to that of electron microscopy.
Photoactivated
localization microscopy incorporates into a sample special fluorescent proteins that can be toggled between on and off states when hit with a particular wavelength of light.
Betzig and Moerner, working separately, developed a different method known as single - molecule
localization microscopy.
