About the cover

May 2017 Volume 9 No 5

Cell membranes are a crucial component of biological systems and they fulfil a variety of essential roles, including the compartmentalization of chemical reactions as well as enabling the formation of concentration gradients. Molecules and ions, acting as chemical signals, must be transported across cell membranes to mediate a range of cellular functions. A collection of articles in this issue discuss artificial methods for transporting chemical information across lipid bilayers. The cover image shows a synthetic transmembrane pore — formed by the self-assembly of a-helical peptides — developed by a team led by Hagan Bayley and Derek N. Woolfson and described on page 411.
