Advances in Microscopy and Its Applications with Special Reference to Fluorescence Microscope: An Overview

The microscope has revolutionized the understanding of an organism's structural details and cellular functions. With the invention of highly evolved microscopes, the diagnosis and treatment of diseases has gained momentum. Technology has immensely helped demonstrate cellular events like phagocytosis, cell movement, cell division, etc. with enhanced temporal and spatial resolution. One of these advanced inventions is the fluorescent microscope which has enabled scanning through various physiological activities of the cell. A fluorescence microscope uses the property of fluorescence to create an image. In addition to visualizing the structural details of the cells, a fluorescence microscope also aids in witnessing cellular activities. With an immunofluorescence microscope, cellular antigens can be localized. This chapter highlights the basics of microscopy, types of microscopes, principles, and types of fluorescence microscopes, and recent advances in microscopy and its application.
