Developments and applications of electrophoresis

12 Jan 2012

Electrophoresis is a very useful separation method employed in a great variety of applications, including the separation and analysis of biological samples (e.g. DNA and proteins) and environmental samples (e.g. pesticide or pollutant analysis). Electrophoresis comes in various different forms (capillary or gel electrophoresis for example) making it a very versatile and adaptable technique.

Analytical Methods presents an excellent forum for advances and applications of this technique, and below is a sample of the high-quality work we have published in this area. These articles are free to access until the 13th February 2012 so make the most of this and take a look!

The Analytical Methods Committee (AMC) are announcing the open nominations for the 2012 L S Theobald Lectureship. Information on the nominating process can be found here.

The LS Theobald Lectureship is awarded to someone who has made a significant contribution to analytical chemistry in an area relevant to the work of the Analytical Methods Committee. (The AMC is a sub-committee of the RSC Analytical Division) and its sub-committees. It is not a requirement that the recipient should be a member of the RSC or have contributed directly to the work of the AMC or its sub-committees.

The closing date for nominations is 31 January 2012.

Issue 1 of 2012 now online

06 Jan 2012

Analytical Methods, 2012, Issue 1 front cover

Analytical Methods, 2012, 4(1): 1-314

Happy New Year! Our first issue of 2012 is now online for you to read.

On the front cover is work from Daniel Attinger of Columbia University, New York, USA and his colleagues from other US institutions.

Their study proposes that images of stains from 100-nanolitre drops can be automatically identified as signatures of fluid composition and substrate chemistry, which has implications for areas such as biological testing.

They used classification algorithms to identify unknown stains, and demonstrated a high level of accuracy.

Identification of fluid and substrate chemistry based on automatic pattern recognition of stains
Namwon Kim, Zhenguo Li, Cedric Hurth, Frederic Zenhausern, Shih-Fu Chang and Daniel Attinger
Anal. Methods, 2012, 4, 50-57
DOI: 10.1039/C1AY05338H

On the inside front cover, Akira Kotani of the Tokyo University of Pharmacy and Life Sciences, Japan, performed alongside international collaborators from the USA and Korea.

They report the ability to detect sporadic mutations with high sensitivity using a mutation scanning assay, which employs thermostable endonuclease V (EndoV) and DNA ligase.

Their microchip method is shown to be considerably faster than conventional capillary gel electrophoresis.

Akira Kotani, Małgorzata A. Witek, John K. Osiri, Hong Wang, Rondedrick Sinville, Hanna Pincas, Francis Barany and Steven A. Soper
Anal. Methods, 2012, 4, 58-64
