Ultrafast UV Two-Dimensional Spectroscopy Confirms Electron Transfer between Tryptophan and Other Molecules

Tryptophan is an amino acid, one of the building blocks of proteins. It is used extensively to study how proteins change their 3D structure, and also how they interact with other proteins and molecules. This is studied with a fluorescence technique called FRET, which measures the transfer of energy from tryptophan to another molecule.

2D IR Spectroscopy Helps Study Therapeutic Mechanism of Anti-Viral Drug

A newly developed spectroscopy method is helping to clarify the poorly understood molecular process by which an anti-HIV drug induces lethal mutations in the virus's genetic material. The findings from the University of Chicago and the Massachusetts Institute of Technology could bolster efforts to develop the next generation of anti-viral treatments.

McPherson Introduces CCD-UV Absorbance Spectrophotometer

Fast DUV Spectrophotometer
McPherson’s newest VUVAS spectrophotometer capitalizes on the speed and sensitivity of direct detection, ultraviolet sensitive CCD detectors. Faster data acquisition enables more complex data sets involving spectral response vs. temperature or time. Fast acquisition also protects against potential measurement errors due to changing sample or environmental conditions.

Tunable Infrared Laser Direct Absorption Spectroscopy Identifies Methane’s Origins

Methane is a potent greenhouse gas, second only to carbon dioxide in its capacity to trap heat in Earth’s atmosphere for a long time. The gas can originate from lakes and swamps, natural-gas pipelines, deep-sea vents, and livestock. Understanding the sources of methane, and how the gas is formed, could give scientists a better understanding of its role in warming the planet.

McPherson Offers Compact Double-Monochromator for Standoff Raman Spectroscopy

Standoff Raman spectroscopy is an optical sensing technique. Among other things, it can be used to detect and identify chemical, biological and explosive activity. There is an ongoing national and international scientific effort to improve these types of detectors. The goal is to form sensing networks to provide early warning for a variety of chemical, biological, radiological, nuclear or explosive (CBRNe) weapons of mass destruction (WMD).

Raman Spectroscopy Can Successfully Detect Cancerous Tissue Following Laser Ablation

Surgeons rely on 200-year-old techniques based on sight and touch when removing cancer, to determine how much to remove and what to leave alone. Laser technology pioneered at Florida Atlantic University has the promise to help a surgeon better determine if an area is cancer or healthy tissue. Moreover, when combined with laser treatment for cancer, this work lays the groundwork for laser robotic treatment of cancer.
