Fluorescence microscopy is a major tool with which to monitor cell physiology. Although the fluorescence microscope cannot provide spatial resolution below the diffraction limit of specific specimen features, the detection of fluorescing. Polarized fluorescence microscopy,14,15,16,17 can be used to determine the average. It is thus conceivable that superresolution fluorescence microscopy can also be achieved by determining the position of each fluorescent probe in a sample with high precision. A guide to superresolution fluorescence microscopy ncbi. Resolution microscopy and its applications in fast and complex biological systems manasa v. In principle, clsm can achieve a better resolution than widefield fluorescence microscopy but, to obtain a significant practical advantage, the pinhole needs to be closed to an extent where most of the light is discarded heintzmann et al. A fluorescence microscope is an optical microscope that uses fluorescence and. By combining a focused laser for excitation and a pinhole for detection, confocal microscopy can, in principle, have a factor of v2 improvement in the spatial resolution.
