Invited for this months cover is the group of Prof. Maxim V. Berezovski. The cover picture shows the two‐dimensional separation of unfolded (green) and folded (red) forms of G‐quadruplex (GQ) DNA. The first dimension is kinetic capillary electrophoresis (KCE) separation of unfolded and folded DNA with different K + concentrations in solution; the second dimension is ion mobility mass spectrometry separation of DNA conformers in the gas phase. DNA folding into a compact GQ structure is mediated by K + ions. For more details, see the Full Paper on p. 58 ff.
