  DNA and Carbon nanotubes (CNTs) have unique physical, mechanical and
electronic properties that make them revolutionary materials for advances in
technology. In state-of-the-art applications, these physical properties can be
exploited to design a type of bio-nanorobot. In this paper, we present the
behaviors of DNA-based nanotweezers and show the capabilities of controlling
the robotic device. The theoretical calculations are based on the
Englander-Peyrard-Bishop model for DNA. Furthermore, the influence of the
Casimir force between on the opening and closing of nanotweezers is studied in
comparison with the stretching forces of DNA.
