摘要： We theoretically investigated negative entropy S of biopolymer which passes through a nanometer pore(such as alpha-hemolysin), especially entering process and escaping process, on the basis of which we also studied biopolymer entering-pore time tau(ent), biopolymer entering mean velocity nu(ent), biopolymer escaping-pore time tau(esc), and biopolymer escaping mean velocity nu(esc), respectively. Our results illustrate that the entering and escaping processes of biopolymer depend on its negative entropy, and entering process is more difficult than escaping process for biopolymer translocation. This tremendous difference between the two processes will offer a useful engineering hint for single macromolecule identification.
