HOT Article: Biomagnetic glass beads for SERS analysis

23 May 2012

Zhao et al., Anal. Methods, 2012, Advance Article

Bing Zhao and Yukihiro Ozaki from Jilin University and Kwansei Gakuin University, respectively, have together with colleagues developed a novel surface-enhanced Raman scattering (SERS)-based detection method for proteins using magnetic glass beads. Target proteins or molecules with a specially recognized feature can be captured and separated by the magnetic nanoparticles. Click on the title below to read more about this new method.

Chemometrics in analytical science

21 May 2012

By Rebecca Brodie, Deputy Editor.

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!

A quantitative assessment of the chemical variation in food grade polyethylene cling film, a common wrapping material for illicit drugs, using attenuated total reflection-Fourier transform infrared spectroscopy

Holman et al., Anal. Methods, 2012, Advance Article

Forensic investigators often encounter cling film as a wrapping for illicit drugs. Using attenuated total reflection-Fourier transform infrared spectroscopy (ATR-FTIR) Stephen W. Holman and colleagues from Anglia Ruskin University, Cambridge, UK, have been studying the level of the chemical variation in food grade low-density polyethylene (LDPE) cling film. Click on the below title to read more about their research.

Statistical analysis of discrete encapsulation of nanomaterials in colloidal capsules

Yomo et al., Anal. Methods, 2012, Advance Article

Tetsuya Yomo and colleagues from Osaka University, Japan, have proposed a measurement and analysis method of discrete encapsulation of nanomaterials in colloidal capsules, in volumes of fL to pL, using fluorescence flow cytometry. The technique could be of great help in the molecular design of intrinsically heterogeneous microcapsules and vesicles. These microcapsules are important for applications that include drug carriers, catalyst reactions, and model cell studies. Click on the title below to read more.

Analytical Methods, 2012, Vol 4, Issue 5, front cover

Linck et al., Anal. Methods, 2012, 4, 1215-1220

Take a look at the latest issue of Analytical Methods, complete with two striking covers (if we do say so ourselves).

The front cover highlights work from Ute Resch-Genger of BAM Federal Institute for Materials Research and Testing, Berlin and his collaborators from across Germany. They have established an improved signal amplification protocol for biological assays using rolling circle amplification RCA, direct enzymatic labeling and the potential Cy3-substitute DY-555. The authors say their straightforward detection protocol can be applied to many other assay formats using a DNA primer to improve their detection limits, such as immunoassays, and that the strategy could be attractive for point-of-care diagnostics.

DOI: 10.1039/C2AY05760C

Featured on the inside front cover is a communication from Erqun Song, Yang Song and their colleagues from Southwest University, Chongqing, China. They report the one-step synthesis of N-acetylglucosamine-functionalized gold nanoparticle (NAG–AuNP), which then served as a facile, economic, highly sensitive and selective sensor for the detection of lectin from wheat germ, based on colorimetric and resonance light scattering signals. The authors expect that their new nanoparticles could be adapted for many applications in the future.

By Rebecca Brodie, Deputy Editor.

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
