Linear Polymer Chain

By using extensive all-atom molecular dynamics simulations of an atactic linear polymer chain, we unveil the role of pressure in the coil-to-globule transition of poly(N-isopropylacrylamide) (PNIPAM).

Three types of nanoparticles, including hydrophobic nanoparticles, hydrophilic nanoparticles, and hydrophilic nanoparticles coated with lipids, were found by our molecular dynamics simulations to be transported across the pulmonary surfactant monolayer, but via different pathways, which affect their subsequent interactions with target cell membranes.
