Estimated millions of tons of plastic are dumped annually into oceans. Plastic has been produced only for 70 y, but the exponential rise of mass production leads to its widespread proliferation in all environments. As a consequence of their large abundance globally, microplastics are also found in […]

OBJECTIVES
The project is based on a recent publications showing the importance of membrane tension for interaction of nanoparticles with cells1–3. Deformation of cells and compression of lipid bilayers by strongly adsorbing nanoparticles is related to a non-chemical and non-biological mechanism of recently discovered antibacterial action of nanoparticles.

An original coarse-grained model for peroxidised phospholipids is presented, based on the MARTINI lipid force field. This model results from a combination of thermodynamic modelling and structural information on the area per lipid, which have been made available recently. The resulting coarse-grained lipid molecules form stable bilayers, […]
