Graphene/MoS(2) Nanohybrid for Biosensors

Graphene has been studied a lot in different scientific fields because of its unique properties, including its superior conductivity, plasmonic property, and biocompatibility. More recently, transition metal dicharcogenide (TMD) nanomaterials, beyond graphene, have been widely researched due to their exceptional properties. Among the various TMD nanomaterials, molybdenum disulfide (MoS(2)) has attracted attention in biological fields due to its excellent biocompatibility and simple steps for synthesis. Accordingly, graphene and MoS(2) have been widely studied to be applied in the development of biosensors. Moreover, nanohybrid materials developed by hybridization of graphene and MoS(2) have a huge potential for developing various types of outstanding biosensors, like electrochemical-, optical-, or surface-enhanced Raman spectroscopy (SERS)-based biosensors. In this review, we will focus on materials such as graphene and MoS(2). Next, their application will be discussed with regard to the development of highly sensitive biosensors based on graphene, MoS(2), and nanohybrid materials composed of graphene and MoS(2). In conclusion, this review will provide interdisciplinary knowledge about graphene/MoS(2) nanohybrids to be applied to the biomedical field, particularly biosensors.
