Determining Chlorophyll a Using Fluorimetry Chlorophyll can be measured both by fluorimetry and spectrophotometry as an indicator of the abundance of photosynthetic organisms in salt and fresh water. In fresh water, levels of chlorophyll are also a vital factor in determining water quality. Read More

Continuously Variable Filters in Fluorescence Spectroscopy   Interference filters are considerably smaller and lighter than grating monochromators and offer greatly increased potential grasp of energy compared to monochromators. When properly designed, an interference filter is capable of collecting several hundred or even several thousand times the quantity of light collected by a monochromator with the same bandwidth.    Read More           Combining Far-Red Fluorescent Silk and Green Light to Destroy Harmful Bacteria   Researchers have transferred a far-red fluorescent protein to the genetic composition of a silk hybrid material, thereby enabling the material to attack bacteria upon being illuminated by a green light.

What is the Difference between Fluorescence and Phosphorescence?   In this article, we look at the two types of photoluminescence, fluorescence and phosphoresence, and how their luminescent mechanisms differ.       An Introduction to Fluorescence Spectroscopy   Spectroscopy is a broad technique, with many different types available to researchers. Each type of spectroscopy measures different bandwidths of radiation, and can be used to determine different chemical and material properties. In this article, we look at fluorescence spectroscopy.       What is X-Ray Fluorescence (XRF)?   X-rays are a part of the electromagnetic spectrum and are on the higher energy side of the ultraviolet rays. They are expressed in terms of their wavelength in nanometers (nm) or their energy in kilo electron volts (keV).       Fluorescence and Absorbance Spectrometer - Duetta™   This innovative spectrometer allows the measurement of both fluorescence and absorbance, and can also be used either just as fluorometer, or as UV-Vis-NIR spectrometer for absorbance measurement.       Shimadzu Corporation Releases New LIGHTVISION Near-Infrared Fluorescence Imaging System   The LIGHTVISION near-infrared fluorescence imaging system is for visualizing lymph and blood vessels to support treatment of breast cancer. Shimadzu Corporation has entered the medical near-infrared camera market with the release of our new LIGHTVISION near-infrared fluorescence imaging system.
