Fluorescence News
Fluorometry could protect valuable vineyards
Aug 1, 2007 — A method that accurately detects the presence of natural antimicrobial agents in grapevines through fluorescence could aid grape growers in protecting their valuable crops from a variety of potentially destructive pathogens. Although techniques...
Optical Interference Filters for Fluorescence Spectroscopy and Microscopy
Aug 1, 2007 — Fluorescence techniques are important in biological applications because they enable discrimination between different types of materials and structures. Instruments based on fluorescence techniques include flow cytometers, microarray scanners and...
Tumor ‘paint’ reveals cancer boundaries
Aug 1, 2007 — When removing malignant tumors, it is important for surgeons to know that they have removed all the cancerous cells. This is especially important in the brain, where more than 80 percent of malignant cancers recur around the edges of the surgical...
FISH-ing for cancer just got easier
Jul 1, 2007 — Fluorescence in situ hybridization (FISH) can detect chromosomal mutations that cause cancer, but the technique can take days to perform and cost hundreds of dollars. Consequently, the method is not yet widely used in clinical settings. However,...
STED Microscope Inventor to Receive Springer Prize
Jun 13, 2007 — This year’s recipient of the Julius Springer Prize for Applied Physics is Göttingen, Germany-based researcher Stefan W. Hell for his revolutionary discovery that resolutions far below the diffraction limit can be achieved in a fluorescence...
Spectroscopy Tools Developed
GAITHERSBURG, Md., June 11, 2007 -- Calibration tools have been developed to help correct and confirm the performance of analytic instruments that identify substances based on fluorescence. Recent years have seen a significant increase in the development and use of...
Fluorophotometric method detects compounds in drug tablets
May 1, 2007 — Researchers at Yangzhou University in China have employed fluorophotometry — a process used for quality control and pharmaceutical analysis — to determine phenothiazine drugs in commercial tablets. The technique offers a lower detection limit than...
Optical properties
May 1, 2007 — The 295-page volume Optics of Biological Particles represents the Proceedings of the NATO Advanced Research Workshop on Fluorescence and other Optical Properties of Biological Particles for Biological Warfare Agent Sensors, Novosibirsk, Russia, Oct....
