What is Fluorescence Microscopy?
Fluorescence microscopy is a microscopy technique that enables imaging by exciting a sample to emit fluorescence signals. Fluorescent molecules emit light at longer wavelengths following the absorption of light at particular wavelengths, which forms the fundamental principle of their operation. Fluorescence microscopy enables the observation of cellular and molecular structures that conventional optical microscopes cannot visualize clearly. Through the application of specific fluorescent markers, researchers can use fluorescence microscopy to differentiate molecules or cell components within intricate biological samples while accurately identifying their locations and dynamic movements both within and outside cells. Fluorescence microscopy serves as an essential tool in cell biology, immunology, cancer research, neuroscience, and drug screening research fields. The technique exhibits high sensitivity and spatial resolution capabilities while enabling multiplex labeling, which permits multiple fluorescent dyes and probes to operate together in revealing complex biological processes. The ongoing progress in fluorescence microscopy combined with sophisticated imaging technologies has significantly driven the comprehensive advancement of basic research along with clinical applications.
