Bending Deformation

This paper investigates the bending deformation of a cantilever biosensor based on a single-walled carbon nanotube (CNT) and single-walled boron nitride nanotube (BNNT) due to bioparticle detection. Through 3-D modeling and simulations, the performance of the CNT and BNNT cantilever biosensors is analyzed. It is found that the BNNT cantilever has better response and sensitivity compared to the CNT counterpart. Additionally, an algorithm for an electrostatic-mechanical coupled system is developed. The cantilever (both BNNT and CNT) is modelled by accounting that a conductive polymer is deposited onto the nanotube surfaces. Two main approaches are considered for the mechanical deformation of the nanotube beam. The first one is differential surface stress produced by the binding of biomolecules onto the surface. The second one is the charge released from the biomolecular interaction. Also, different ambient conditions are considered in the study of sensitivity. Sodium Dodisyl Sulphate (SDS) provides better bending deformation than the air medium. Other parameters including length of beam, variation of beam’s location, and chiralities are considered in the design. The results are in excellent agreement with the electrostatic equations that govern the deformation of cantilever.

First Principles Study

First-principles studies on electronic structures, transverse polarizability, and shielding of two coaxial hybrid double-walled nanotubes consisting of carbon nanotube (CNT) and boron nitride nanotube (BNNT), namely CNT@BNNT and BNNT@CNT, are conducted. The interaction between inner and outer tubes is considerably weak. The polarizability of single-walled CNT is larger than that of single-walled BNNT due to the different electronic properties. In BNNT@CNT, the outer CNT with delocalized π-electrons character demonstrates a nearly complete shielding with the order of 90% of the inner BNNT from the transverse external electric field, while the outer BNNT has a relative small shielding of about 40% for the inner CNT in CNT@BNNT system. Moreover, the shielding of the outer tube can be appreciably enhanced by increasing the intertube separation.
