Key Points

  • The study aims to understand how DNA nucleobases intercalate within bilayer graphene and bilayer MoS₂.
  • Utilized density functional theory (DFT) to analyze intercalation processes.
  • Compared interaction energies and structural parameters of DNA bases in both materials.
  • Investigated the electronic properties resulting from base intercalation.
  • Adenine shows the highest binding energy with bilayer graphene compared to other bases.
  • Bilayer MoS₂ exhibits significant electronic modulation upon DNA base intercalation.
  • Differential binding strengths suggest varying potential for biosensing applications.

Abstract

The detection and discrimination of DNA bases (adenine, guanine, cytosine, and thymine) are foundational to genomics, diagnostics, and biotechnology. Two-dimensional (2D) layered materials, particularly bilayer graphene (BLG) and bilayer molybdenum...
