Fluorescent Microscopy

Definition

Fluorescent microscopy is a powerful imaging technique that uses fluorescence to visualize and analyze biological specimens. This method involves tagging specific cellular components with fluorescent dyes or proteins, allowing researchers to observe the localization and dynamics of these components within cells or biofilms. By using specific wavelengths of light, fluorescent microscopy enhances contrast and detail, making it particularly useful for studying complex structures like biofilms in the context of bioremediation.
