The manipulation of biomolecules in nano-scale channels is quite interesting but full of challenge. One of the preconditions is to understand the transport process of biomolecules and ions in nanofluidic channels. In this issue, numerical simulations were carried out at a molecular level. The model of polypeptide GNNQQNY was introduced as a protein molecule under different conditions varying the driving factors like channel height, solution concentration and electric field intensity. The simulated results were discussed and analysed by comparing the molecular distribution, protein molecules' movement amplitude and potential energy. The decreasing channel height greatly influences the movement of proteins due to the more obvious electric double layer (EDL) effect. The increasing ionic concentration helps the passage of protein molecules while the layered concentration phenomenon of molecules and ions nearby the channel wall aggravates with the average ionic density. The electric field strength was also found to be an effective tool to control the passage of protein molecules. The results were helpful to understand the transport of biomolecules in nanofluidic channels.
