WebAlso known as non-linear multiphoton, two-photon laser scanning or simply two-photon microscopy, it relies upon the principle of two-photon absorption. ... Traditional fluorescence microscopy uses a single photon to excite fluorescent dyes using mainly visible excitation wavelengths (390-700 nm). After excitation the electron will drop back ... WebMultiphoton fluorescence microscopy is a powerful research tool that combines the advanced optical techniques of laser scanning microscopy with long-wavelength nonlinear multiphoton fluorescence excitation to capture high-resolution, three-dimensional images of specimens tagged with highly specific fluorophores.
