Combining the specific recognition ability of DNA molecules with the superior physical and chemical properties of two-dimensional (2D) layered materials, a DNA-2D layered nanomaterial sensing platform was constructed. More and more researchers are devoted to develop this sensing platform, which has become one of the important research directions in the field of chemical/biological sensors. In view of the rapid development of the 2D layered materials, this paper firstly introduces the construction principle of the DNA-2D layered material sensing platform. Then we mainly review the application of the sensing platform in the analysis of chemical and biological molecules, including metal ions, mycotoxins, ATP, amino acid, antibiotics, nucleic acids, proteins and cancer cells. Finally, the future of this sensing platform is prospected.

Key words: two-dimensional layered nanomaterial, DNA, sensing platform, analysis
