Cholesterol artefacts

Be aware of using proper mdp settings when simulating cholesterol, as it might cause artificial phase separation if you don't, according to Javanainen et al: arXiv:2009.07767

Organic semiconductors

Druggable Martini

Tpathways.pnghe forthcoming Martini 3.0 forcefield opens the way to high-throughput drug screening. Unbiased simulations show reversible binding of a large variety of ligands to both soluble and membrane-embedded proteins, reproducing known pathways and binding sites, as well as correct binding free energies.
