Dynamic Modelling of 2D Nano-manipulation Based on AFM in Liquid Environment

Pushing of the nanoparticle using Atomic Force Micro/nanoscopy (AFM) probe as a nano manipulator was modelled in air and the dynamic behaviour of tip and nanoparticle was investigated. In this work, we focus on submerged manipulation in liquid and analyze the artificial nano-object manipulation by means of theoretical forces analysis. Significance of distance, contact and hydrodynamic forces were discussed and then a new dynamic modeling of gold particle manipulation on a silicon substrate was performed in liquid. The results of the model shows that the critical time and force of nanoparticle movement on substrate have an almost 5~6% variation in comparison with the manipulation in air.
