Calculations of the average velocity and the effective diffusion coefficient indicate that inertial effects always play a destructive role in the passive transport of nanoparticles, whereas in the case of active transport they may increase the average velocity and play a constructive role in the high-temperature region when the thermal energy of the particle is larger than the energy barrier of the near-surface potential. |
