Total Reflection Fluorescence Microscope

Total internal reflection fluorescence microscopy utilizes evanescent waves generated by total internal reflection at the glass-sample interface to excite fluorescence in the sample surface layer, achieving high signal-to-noise ratio imaging within a depth of approximately 100 nanometers. It is used for observing cell membrane dynamics, single-molecule tracking, and surface analysis of materials.
Selection
When selecting, consider matching the laser wavelength with fluorescent dyes, ensure the objective lens has a numerical aperture greater than 1.4, and include temperature control and live cell culture systems. Choose between inverted or upright structures based on sample thickness, and ensure the setup includes a fast camera and an anti-vibration table.
