A potential sensing mechanism for DNA nucleobases by optical properties of GO and MoS₂ Nanopores.

ABSTRACT: We propose a new DNA sensing mechanism based on optical properties of graphene oxide (GO) and molybdenum disulphide (MoS₂) nanopores. In this method, GO and MoS₂ is utilized as quantum dot (QD) nanopore and DNA molecule translocate through the nanopore. A recently-developed hybrid quantum/classical method (HQCM) is employed which uses time-dependent density functional theory and quasi-static finite difference time domain approach. Due to good biocompatibility, stability and excitation wavelength dependent emission behavior of GO and MoS₂ we use them as nanopore materials. The absorption and emission peaks wavelengths of GO and MoS₂ nanopores are investigated in the presence of DNA nucleobases. The maximum sensitivity of the proposed method to DNA
