Total internal reflection fluorescence (TIRF) microscopy.
Total internal reflection fluorescence (TIRF) microscopy (TIRFM) is an elegant optical technique that provides for the excitation of fluorophores in an extremely thin axial region ("optical section"). The method is based on the principle that when excitation light is totally internally reflected in a transparent solid (e.g., coverglass) at its interface with liquid, an electromagnetic field, ca...
متن کاملTopic Introduction Total Internal Reflection Fluorescence Microscopy
The goal in fluorescence microscopy is to detect the signal of fluorescently labeled molecules with great sensitivity and minimal background noise. In epifluorescence microscopy, it is difficult to observe weak signals along the optical axis, owing to the overpowering signal from the out-of-focus particles. Confocal microscopy uses a small pinhole to produce thin optical sections ( 500 nm), but...
متن کاملA Thin Layer Imaging with the Total Internal Reflection Fluorescence Microscopy
Total internal reflection fluorescence microscopy (TIRFM) is an optical technique that allows imaging of a thin layer of the sample with a thickness of about 100-200 nm. It is used in science of cell biology to study cellular processes, especially near the membranes of living cells. This method is based on the total internal reflection phenomenon, where the evanescent wave is generated in the l...
متن کاملTotal internal reflection fluorescence (TIRF) microscopy. I. Modelling cell contact region fluorescence.
Total Internal Reflection Fluorescence (TIRF) is a powerful technique for visualizing focal and close contacts between the cell and the surface. Practical application of TIRF has been hampered by the lack of straightforward methods to calculate separation distances. The characteristic matrix theory of thin dielectric films was used to develop simple exponential approximations for the fluorescen...
متن کاملTotal internal reflection fluorescence.
Total internal reflection fluorescence (TIRF) is an optical effect particularly well-suited to the study of molecular and cellular phenomena at liquid/solid interfaces. Such interfaces are central to a wide range of biochemical and biophysical processes: binding to and triggering of cells by hormones, neurotransmitters, and antigens; blood coagulation at foreign surfaces; electron transport in ...
