Two-Photon Excitation Microscopy for Three-Dimensional Imaging of Living Intact Tissues

Research output: Chapter in Book/Report/Conference proceedingChapter

Abstract

Two-photon excitation microscopy (2PM) is an alternative to confocal microscopy that provides attractive features for imaging deep into intact tissues and reducing overall photo-toxicity. This approach enables dynamic cellular measurements, and the depth penetration opens up a broad range of experiments that rely on non-invasive intra-vital imaging of cellular and sub-cellular processes. This chapter will detail what two-photon excitation is, how it enable imaging in practice, and how its underlying photophysics leads to both its advantages and limitations. The chapter will also cover how instrumentation design can be optimized for 2PM, and show how this approach can be extended to other related non-linear microscopies, each of which offer particular advantages. Finally, a few recent examples of 2PM will be presented to highlight its potential impact in neuroscience, developmental biology, immunology, cancer and endocrinology.
