Abstract:
:It was reported that a single-strand DNA (ssDNA) could be inbreathed spontaneously into a carbon nanotube (CNT). In this work, the complementary process, i.e. pulling a piece of ssDNA out of a single-walled (SW) CNT, is simulated using molecular dynamic methods. The pulling force is found to fluctuate around a plateau of 250 pN with the base types identifiable by the varying amplitudes. One may thus numerate the bases in DNA by counting the fluctuation repetition or detect the information of DNA sequence by considering the fluctuating amplitudes.
