Related to confocal microscopy: fluorescence microscopy
Microscopy that permits high-resolution analysis of serial optical sections (microscopic tomograms) into the depths of tissues or cells.
See also: microscopy
examination with a microscope.
a technique for obtaining high resolution images and 3-D reconstructions of biological specimens; a laser light beam is expanded to make optimal use of the optics in the objective lens and is turned into a scanning beam via an x-y deflection mechanism and is focused to a small spot by the objective lens onto a fluorescent specimen. The mixture of reflected light and emitted fluorescent light is captured by the same objective and after conversion into a static beam by the x-y scanner device is focused onto a photodetector (photomultiplier) via a dichroic mirror (beam splitter) to create the final image. Called also laser scanning microscopy; confocal scanning laser microscopy.
the mixing of antibody with an antigen such as a virus on a specimen grid so as to increase the probability of visualizing a virus and to identify (type) the kind of virus present in the specimen, or antibody may be conjugated with gold and used to visualize and determine the location of specific antigenic determinants on a specimen.
