Fluorescence

Diagnostic instruments such as blood analyzers and flow cytometers utilize induced fluorescence to detect bio-factors of interest in a heterogeneous sample.

Lifetime fluorescence is a subset of fluorescence spectroscopy in which the time between excitation and relaxation is measured, rather than just the intensity of the emitted energy. The technique is used primarily in biological applications, but has a number of other uses as well. Lifetime fluorescence is a well-established niche market.

This month's Technology Forum looks at the topic of fluorescence and the trends and issues surrounding it. Joining us for this discussion are David M. Jameson, Ph.D., University of Hawaii at Manoa; Michael W. Allen, Ph.D, Product Manager, Thermo Fisher Scientific; and Patrick J. Treado, Founder & CTO, ChemImage Corporation.

Although the market for dedicated single-tube luminometers now pales in comparison to multimode fluorometers and microplate readers, such luminometers continue to satisfy a niche market. The relative simplicity and therefore low cost is their major advantage, which is appealing to smaller life science laboratories.

Although overshadowed by other technologies, demand for fluorescence microscopy is already strong and is growing rapidly. The technology is proving to be very useful for specific life science applications.
