Two-photon microscopy Two photons of low energy (infrared range) can excite a fluorophore → emission of a fluorescence photon at a higher energy Excitation is restricted to a tiny focal volume (rejection of out-of-focus signals) Longer wavelengths penetrate deeper into tissue (1 mm) Lower energy photons cause relatively low damage outside the focal volume → in vivo imaging
