Fluorescence provides a powerful means of achieving molecular contrast in a wide range of biological and medical applications. For example, it can be used to detect the autofluorescence from naturally occurring fluorophores in biological tissues and can provide contrast between different states of diseased tissue.  Targeted probes can also be applied that localize in specific cellular locations and provide extrinsic image contrast or that bind to specific receptors on the cell membrane.  Over the past two decades not only have we seen remarkable advances in tissue diagnostic techniques based on fluorescence contrast, but we have also discovered the significant role that time-resolved or fluorescence lifetime techniques have to play in medical diagnosis. Until a decade ago progress in this area had been led by a small group of investigators; now many of the techniques are maturing and are ready to be adopted by innovative mainstream researchers and used in clinical settings. This broadly accessible book lays out the fundamentals, the state-of-the-art techniques and their current applications to help accelerate the use and proliferation of fluorescence techniques in tissue diagnostics for both research and clinical applications purposes.
