Abstract
The nanoindentation of phospholipid (DMPC) layer by the carbon nanotubes (CNTs) of different diameters was studied using steered molecular dynamics (SMD) method. Four carbon nanotubes of different diameters d were used (d ≈ 9.5, 13.5, 16 and 20 A). The nanotubes were pushed through the 1,2-dimyristoyl-sn-glycero-3-phosphocholine (DMPC) layer with a constant speed. Three different pulling velocities were applied: 0.5, 1.5 and 2.5 m/s. All simulations were performed at the physiological temperature T = 310 K. The force acting on a nanotube during membrane indentation and work and free energy were calculated, presented and discussed.
