Analyst Issue 7 now online!

Analyst Issue 7 is now available online! Take a look at our new wonderful covers featuring the latest discoveries in the field of analytical chemistry.

Julia Laskin and her group used nanospray desorption electrospray ionization for spatial profiling of chemical gradients generated by microbial communities on plate, and detected metabolites and lipids on the colonies and the surrounding agar. This methodology, just featured on the outisde front cover of Issue 7, might facilitate future studies on interactions between bacterial colonies.

Our inside front cover shows the work of Ahu Arslan Yildiz and colleagues from the Institute of Material Research and Engineering in Singapore. The researchers analysed the human ether-à-go-go-related gene (hERG) potassium channel, which is known to be involved in inherited or drug-induced long QT syndrome. Surface Plasmon Fluorescence Spectroscopy and Imaging Surface Plasmon resonance techniques were used to investigate the interactions between hERG and the drug. According to the study, this new approach could be applied to other membrane proteins for drug screening or other prorein-related interactions.

Finally, our outside back cover presents the Tutorial Review written by Sergei Kazarian and Andrew Chan from Imperial College London, who outline the most recent advances and applications of attenuated total reflection Fourier transform infrared spectroscopy imaging in biomedical studies. In addition, future developments in the area are discussed.
