Front cover: Taira et al., Analyst, 2012, 137, 2006-2010
The latest issue of Analyst is now available for you to browse, and we head east for all three covers.
There’s nanoparticle-assisted laser desorption/ionisation MS from Japan, electrochemical biosensing from Korea, and microextraction from Taiwan.
On the front cover is work from Shu Taira of the School of Material Science at the Japan Advanced Institute of Science and Technology (JAIST), Ishikawa, Japan, and colleagues.
They analysed oligonucleotides by nanoparticle-assisted laser desorption/ionization (nano-PALDI) mass spectrometry, and demonstrated that iron-based nanoparticles may serve as the assisting material of ionization for genes and other biomolecules.

The inside front cover features a HOT paper from Hye Jin Lee of Kyungpook National University, Daegu-city, Republic of Korea and her collaborators from Korea and the UK.
Inside front cover: Nam et al., Analyst, 2012, 137, 2011-2016
A novel electrochemical detection methodology is described for the femtomolar detection of proteins which utilizes both DNA aptamer-functionalized nanoparticles and a surface enzymatic reaction. The authors say this offers a significant improvement compared to conventional electrochemical-based immunoassay approaches and provides a foundation for the practical use and incorporation ofnanoparticle-enhanced detection into electrochemical biosensing technologies. This Communication is part of our web theme on Future Electroanalytical Developments.

Finally, the back cover highlights research from Shang-Da Huang of National Tsing Hua University, Hsinchu, Taiwan and co-workers.
They have developed a rapid, simple equilibrium liquid-phase microextraction method based on manual shaking-enhanced, ultrasound-assisted emulsification microextraction (MS-USAEME) and measurement by UPLC-UV for the determination of five endocrine-disrupting phenols in seawater samples and in detergent samples.
