The latest issue of Analyst is now available online.
Featured on the front cover is work from D. Marshall Porterfield and colleagues from Purdue University, USA, which illustrates single-walled carbon nanotubes modified with a single strand of DNA on Pt black. This nanocomposite 
showed enhanced biosensor performanace and could potentially be used for a variety of physiological sensing applications.
Microbiosensors based on DNA modified single-walled carbon nanotube and Pt black nanocomposites, Jin Shi, Tae-Gon Cha, Jonathan C. Claussen, Alfred R. Diggs, Jong Hyun Choi and D. Marshall Porterfield, Analyst, 2011, 136, 4916-4924.
The inside front cover of this issue features work from Detlef Günther of ETH Zurich and colleagues. They studied the addition of methane or methanol/water to an inductively coupled plasma (ICP) and found that it significantly improved the sensitivity of laser ablation-ICP-MS for some elements.
Sensitivity improvement in laser ablation inductively coupled plasma mass spectrometry achieved using a methane/argon and methanol/water/argon mixed gas plasma, Daniel Fliegel, Christian Frei, Gisela Fontaine, Zhaochu Hu, Shan Gao and Detlef Günther, Analyst, 2011, 136, 4925-4934.
On the back cover is research from Shuping Bi and colleagues from Nanjing University, who studied the effect of five different electrode pretreatments on the coverage of monolayers of dodecanethiol on gold.
Studies on the effect of electrode pretreatment on the coverage of self-assembled monolayers of dodecanethiol on gold by electrochemical reductive desorption determination, Guiying Feng, Tianxing Niu, Xueyan You, Zhongwei Wan, Qiuchen Kong and Shuping Bi, Analyst, 2011, 136, 5058-5063.
These articles are all free to access until the 18th December 2011!
