In the recent bionano technology, DNA has considerable attention because it can be used as the materials for novel electronic device due to the π stacking between the base pairs. It was found experimentally that the poly(dA)-poly(dT) DNA is the n type semiconductor and poly(dG)-poly(dC) DNA is the p type one. To obtain the basic design data for the bionano electronics devices by the use of DNA, the mechanical properties such as elasticity should be obtained in detail. Experimental investigation seems to be difficult and the effective computer simulation technique to obtain the practical data described above is strongly required. In the present study, the novel force field for molecular dynamics simulation of macromolecules applicable for its large deformation is developed and the DNA extension characteristics by external force is discussed in detail. The results are compared with the previous work.
