The group of Basdevant performed Martini simulations of the ionic transport through the α-hemolysin protein nanopore, using the polarizable water model. The electric potential difference applied experimentally was mimicked by the application of an electric field to the system. They were able to observe current asymmetry and anion selectivity, in agreement with previous studies and experiments, and identified the charged amino acids responsible for these current behaviors.

Impressive work on using lipid nanoparticles to deliver drugs to tumour cells, featuring large scale Martini simulations. Snapshots show the difference in penetration efficiency between a PEGylated lipid nanodisc (a) and a PEGylated liposome (b), both with a diameter of 40 nm, before (t = 0 ns) and after (t = 1,750 ns) being pulled through a 20 nm pore.
