A recent study from Lanzhou Jiaotong University presented a new fluorescent sensor that can detect permanganate ions in water.
Medical Imaging with Filters and Quantum Dots
February 11th 2011The onset of nanotechnology and targeted therapy methods for a number of pathologies has made it increasingly more difficult to image effectively in the medical field. With that being said, the inception of quantum dots and the improvements to optical filters has made this once daunting task a common practice.
More Raman Analyses Less Fluorescence Interference
February 11th 2011In recent years, the spectroscopy community has observed rapid development of Raman instrumentation and its usefulness in a variety of applications. Routine Raman analysis with 785 nm excitation has served well for the great majority of industrial applications and has become the most favored instrument configuration.
Total Reflectance X-Ray Fluorescence Spectroscopy
February 11th 2011X-ray fluorescence spectroscopy (XRF) provides sensitive analysis of the atomic composition of samples. The technique is particularly well-suited for analyzing the elemental range from sodium to uranium, which covers the majority of the metallic elements.
Market Profile: Lifetime Fluorescence
March 1st 2009Lifetime 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.
Technology Forum: Fluorescence
November 5th 2008This 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.
