Fluorescence-lifetime-based sensing: applications to clinical chemistryand cellular imaging,

摘要

Abstract: ments of fluorescence lifetimes, rather than intensity or intensity ratios, offer many advantages in clinical chemistry and imaging. However, measurements of time-resolved fluorescence are normally associated with complex laser light sources and instrumentation. In this lecture, we show how emerging technology is enabling the design and use of simple instrumentation for time-resolved fluorescence. In particular, it is now possible to imagine lifetime-based measurements of blood gases and blood glucose, and lifetime imaging of calcium and other ions in microscopic samples. !48
