    摘要: Transport of molecules through macromolecular pores is of considerable importance in many biological systems and nanoscale biosensors. In recent years, engineered carbon nanotubes (CNTs) have been developed to function as protein toxin transporters. We present molecular dynamics simulation of the small mastoparan-X peptide transporting through the single-walled CNT (SWCNT) under application of an external electric field force. The molecules studied include a small mastoparan-X peptide, a finite segment of carbon nanotube, and TIP3 water molecules. The external electric field vectors are 1.0, 2.0, 3.0, 4.0, and 10.0 kcal/(mol Å e), respectively. We show that under the external electric field vector of 1.0 kcal/(mol Å e), the transportation of mastoparan-X peptide through SWCNT was accomplished within 12 ns. Our results also show more external electric field vectors would speed up the transportation process.
