Abstract

A study was conducted to demonstrate single-layer transition metal dichalcogenide nanosheet-based nanosensors for rapid, sensitive, and multiplexed detection of DNA. Single- and few-layered transition metal dichalcogenide (TMD) nanosheets (NSs) were synthesized based on the lithium-intercalation method. Transmission electron microscopy (TEM) images, selected area electron diffraction (SAED) patterns, and the corresponding high-resolution TEM (HRTEM) images of the synthesized MoS2, TiS2, and TaS2 NSs were investigated under the study. Atomic force microscopy (AFM) measurements revealed that the thicknesses of the MoS2, TiS2, and TaS2 NSs were approximately 1.1, 1.0, and 1.1 nm.
