Fluorescence microscopy is a powerful technique used in biological and materials science research to visualize and study the properties of fluorescently labeled molecules or structures. This technique involves exciting fluorescent molecules with a specific wavelength of light, causing them to emit light at a longer wavelength that can be captured and visualized using a microscope. Fluorescence microscopy is widely used to study cellular structures, protein localization, gene expression, and other biological processes at the molecular level. It allows researchers to track the movement, interactions, and dynamics of specific molecules within living cells or tissues, providing valuable insights into their function and behavior.
