Gordon F. Kirkbright Bursary Award 2013 announced

03 May 2012

The Gordon F. Kirkbright bursary award is a prestigious annual award that enables a promising student/non-tenured young scientist of any nation to attend a recognised scientific meeting or visit a place of learning.
The fund for this bursary was established in 1985 as a memorial to Professor Gordon Kirkbright in recognition of his contributions to analytical spectroscopy and to science in general. Although the fund is administered by the Association of British Spectroscopists (ABS) Trust, the award is not restricted to spectroscopists.

Applications are invited for the 2013 Gordon Kirkbright Bursary.

For further information contact John Chalmers at, email: vibspecconsult@aol.com

The closing date for entries is 31 December 2012.

By Rebecca Brodie, Deputy Editor.

Ghosh & Mastrangelo, Analyst, 2012, Advance Article

Tridib Ghosh and Carlos H. Mastrangelo from the University of Utah, USA, have developed a new dual slope SPR technique that is 10-fold faster than conventional methods. They have based the technique on the measurement of association and dissociation slopes in two half reactions. Results could be measured in 30 sec compared to 5 mins.

Sensor that smells like a dog

26 Apr 2012

By Aliya Anwar.

Scientists in Korea have developed a biosensor for assessing food quality that mimics the way receptors in a canine nose respond to smells.

Tai Hyun Park and Seunghun Hong and colleagues from Seoul National University made a device that detects hexanal – a volatile compound produced when food is past its best.

A current method to detect compounds emitted by oxidised food is chromatography, but it isn’t portable and it involves a complicated pre-treatment process. To overcome these obstacles, scientists have moved on to semiconductor-based, olfactory cell-based and olfactory receptor protein-based sensors, but they are not as capable as an animal olfactory system in terms of selectivity and sensitivity.

In an animal’s nose, specific odorants bind to the corresponding olfactory receptors with high selectivity, generating a chemical signal. That signal is converted into an electrical signal and then amplified through a pathway in an olfactory sensory neuron (a nerve cell that processes and transmits information by electrical and chemical signalling).

The nanovesicles sit in the carbon nanotube channel. When hexanal is present, it binds to the olfactory receptors, causing an influx of Ca2+ ions into the vesicles. The resulting positive gate potential in the vesicles leads to a decrease in the conductance in the channel

HOT article: “Turn on” electron-transfer-based selective detection of ascorbic acid

“Turn-on” optical detection of parts-per-million (ppm) levels of ascorbic acid in water using a redox-active monolayer on glass

Singh et al., Analyst, 2012, Advance Article

The design and fabrication of monolayer-based sensors for various chemicals, gases, metal ions, explosives and biologically relevant molecules have received much attention recently. In particular, optical sensors are of great interest due to the advantage that the sensing system does not need to be directly wired with large scale electronics.

In this paper, Tarkeshwar Gupta of the University of Delhi, Delhi, India, and colleagues describe the “turn-on” optical detection of parts-per-million (ppm) levels of ascorbic acid in water using a redox-active monolayer on glass.

Their system is based on a nondestructive solution-to-surface one-electron transfer process that can be read out optically with an off-the-shelf UV/vis spectrophotometer.
