HOT Article: A biochip for detecting ephedrine

01 Jun 2012

A surface plasmon resonance-based biochip to reveal traces of ephedrine

D'Auria et al., Anal. Methods, 2012, Advance Article

From Italy, we have a team of scientists that have developed a biochip device that can detect ephedrine. Sabato D’Auria from the Laboratory for Molecular Sensing, IBP-CNR, and colleagues designed the chip to combine an immunochemical method with surface plasmon resonance spectroscopy to detect ephedrine at levels as low as 33 ng per mL. Ephedrine is a chemical precursor used to illegally produce amphetamines and therefore a quick and easy method to detect it is important.

Chemometrics in analytical science

21 May 2012

Used particularly heavily in analytical chemistry and metabolomics, ‘chemometrics’ is the science of using mathematical or statistical methods to extract information from a chemical system. Beginning in the 1970s with the emergence of computer driven scientific investigation, chemometrics frequently uses methods found in applied mathematics, computer science and statistics.

Analytical Methods presents an excellent forum for such work, and below is a sample of the high-quality work we have published in this area. These articles are free to access until 21st June 2012 so make the most of this opportunity and take a look!

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.
