Understanding Fluorescence Microscopy

Fluorescence microscopy utilizes the principles of fluorescence to visualize specimens at a microscopic level. It involves the use of fluorescent dyes or proteins that emit light upon excitation. When these fluorophores are illuminated with specific wavelengths, they emit light of a different wavelength, allowing researchers to observe and analyze structures and processes within cells and tissues.

Key Components

• Excitation Source: Provides the light needed to excite the fluorescent dyes or proteins.
• Fluorescent Dyes/Proteins: Molecules that emit light at specific wavelengths when excited.
• Filters: Select the specific wavelengths of light needed for excitation and emission.
• Detector: Captures the emitted fluorescence and converts it into an image.
