Supramolecular polymer dynamics

The group of Pavan has used Martini in combination with well-tempered metadynamics to study the self-healing capacity of bio-inspired supramolecular polymers. Cool !

Enhanced sampling with iMapD

Check out this new method for fast sampling by Hummer and coworkers. They introduce "iMapD", a method to enhance the exploration in an MD simulation with no prior knowledge of a suitable collective variable. The method was applied to simulations of the Mga2 dimer in Martini and enabled, for the first time, observation of an unbiased dissociation path.

MD simulations reveal chaos in electron transport

Using Martini, we were able to simulate the spontaneous binding and unbinding of electron carriers to photosystem II, one of the key protein complexes in photosynthesis. For more details, please see the full paper:
