Nanotechnology Now - Press Release: Chung-Ang University researchers develop novel DNA biosensor for early diagnosis of cervical cancer: The electrochemical sensor, made of a graphitic nano-onion/molybdenum disulfide nanosheet composite, detects human papillomavirus (HPV)-16 and HPV-18, with high specificity

Molybdenum disulfide (MoS2) 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 MoS2 have opened up multiple research avenues across several fields, including the development of biomolecule sensing and chemical detection platforms, optoelectronics, supercapacitors, and batteries.
