Credit: Journal of Nanobiotechnology Molybdenum disulfide (MoS 2 ) has recently garnered attention among materials science researchers owing to its ability to form two-dimensional nanosheets like graphene. The nanosheets are created by the stacking of S–Mo–S layers interacting via Van der Waals interactions. Additionally, the unique structural, optical, thermal, and electrochemical properties of MoS 2 have opened up multiple research avenues across several fields, including the development of biomolecule sensing and chemical detection platforms, optoelectronics, supercapacitors, and batteries. Traditionally, carbon nanostructures have been employed as an immobilization platform for DNA. In order to substitute carbon with MoS 2 as an effective electrochemical DNA sensor, the electrical conductivity of MoS 2 needs to be improved considerably. Against this backdrop, Associate Professor Eunah Kang and Mr. Youngjun Kim from the School of Chemical Engineering and Material Science at Chung-Ang University, Korea have…
