Structure, dynamics, and other biophysical properties of proteins, nanoparticles, and polymers interacting with membranes are investigated using all-atom and coarse-grained molecular dynamics (MD) simulations. The work aims to help the rational design and control of cell-targeting nanoparticles of protein drugs, self-assembled fibrous biomaterials and synthetic biology, and nanopore-based biosensors.
