Snagging supernova spectra

Date: Jan 1, 2010

Author: David Bradley

Spectroscopy reveals that an extraordinarily bright, very long-lasting supernova named SN 2007bi, spotted in the night sky by a robotic telescope is the first example of the earliest type of star in the universe.

An ab initio simulation of the UV/visible spectra of N-benzylideneaniline dyes

Date: Dec 7, 2009

Author:

The structural parameters and absorption spectra of more than 30 N-benzylideneaniline dyes have been determined with a theoretical scheme combining the time-dependent density functional theory and the polarizable continuum model.

Golden arsenic assessment

Date: Dec 1, 2009

Author: David Bradley

A new light-scattering technique that uses gold nanoparticles can selectively detect arsenic ions, without interference from dissolved alkali and alkali earth metals, improving on water tests based on Raman and SPR. UV-Vis spectroscopy was used in conjunction with tunnelling electron microscopy to characterise the nanoparticles themselves.

Quality of sour cream packaged in cups with different light barrier properties measured by fluorescence spectroscopy and sensory analysis

Date: Nov 9, 2009

Author:

The photooxidation of sour cream packaged in cups with different light barrier properties was investigated by sensory analysis and front face fluorescence spectroscopy.

Methylmercury marker

Date: Nov 1, 2009

Author: David Bradley

Detecting methylmercury usually involves complex sample preparation and a sophisticated analytical procedure. Now, a European team has developed a novel approach to detecting this hazardous substance much more quickly and easily using a new type of fluorescent marker.

Tracing of intracellular zinc(II) fluorescence flux to monitor cell apoptosis by using FluoZin-3AM

Date: Oct 12, 2009

Author:

The zinc(II) probe FluoZin-3AM was used to distinguish between different stages of apoptotic cell (induced by the anticancer agent etoposide) by tracing the intracellular zinc(II) fluorescence flux.

Optical sniffer detects poison gas

Date: Oct 1, 2009

Author: David Bradley

US researchers have developed an optoelectronic nose that can sniff out toxic gases. The sensor is fast and inexpensive and could be used to detect high exposure risk to hazardous industrial chemicals.

Fluorescence of unmodified oligonucleotides: A tool to probe G-quadruplex DNA structure

Date: Sep 14, 2009

Author:

Unlabelled oligonucleotides that form G-quadruplexes can be differentiated from similar sequences that do not contain consecutive guanines on the basis of their fluorescence spectra.

One from the vine

Date: Sep 1, 2009

Author: David Bradley

Kudzu is a weedy vine that has overgrown almost 10 million acres in the southeastern United States. However, it could one day sprout into a dietary supplement to helpe reduce metabolic syndrome in millions of people. Mass spectrometry and UV spectroscopy have now been used to identify and quantify the putatively active isoflavones in extracts of the vine by US scientists.
