Speech title:In vivo three-photon fluorescence microscopy and its potential application in plant-photonics


Abstract: 

Three-photon fluorescence (3PF) is a very typical high-order nonlinear optical effect. 3PF microscopy can dramatically reduce the out-of-focus background in regions far from the focal plane, improving the signal to background ratio (SBR) by orders of magnitude when compared to the commercially available two-photon fluorescence (2PF) microscopy. Thus, 3PF microscopy can improve spatial resolution and imaging contrast, and increase imaging depth effectively. In our previous studies, we have developed a series of three-photon fluorescence intensity and lifetime microscopes. These setups have been employed in cerebral neuron and blood vessel imaging of small animals, as well as non-human primate animals. Recently, our group founds that 3PF microscopy has great potentials for plant-photonics research (e.g. structural and functional imaging of chloroplast), and I would like to share these interesting results in this presentation.
