Molecular dynamics (MD) simulations are in silico methods based on time-resolved simulations of complex systems at the atomistic level . We can derive many thermodynamic and kinetic properties of the system from the MD simulations . Thanks to the current level of computational power and MD methods, we can now study the behavior of substances on membranes even at the atomic level , but they are so far limited by the quality of membrane force fields , long time scales necessary for membrane permeation and hysteresis artefacts for advanced sampling methods . Hence, the availability of these data in large quantities is still quite limited, and MD is used more to model how molecules permeate the membranes .
