Our outside front cover shows the work of Igor Lednev and his group from the State University of New York, USA. The researchers analyse biological specimens using surface- and tip-enhanced Raman spectroscopy (SERS and TERS) and investigate the lack amide I band, commonly used as a marker for interpretation of the secondary protein structure.

Our interesting inside front cover showcases work from Luigi Sanguigno from the Italian Institute of Technology, who describes how fluorescence correlation spectroscopy (FCS) can be misleading in 2D systems. This study highlights the alignment issues and the effects of thermal fluctuations related to FCS in 2D systems and proposes elimination of systematic errors due to the misalignments of membranes.

The outside back cover of this issue introduces negative mode probe electrospray ionization mass spectrometry (PESI-MS) as a tool for biomolecular analysis and cancer dignostics. Mridul Kanti Mandal and colleagues from the University of Yamanashi, Japan, analysed several combinations of solvents and probes to optmise the conditions of ionization for biomolecules such as peptides, proteins and lipids.
