Molybdenum disulfide nanosheets: From exfoliation preparation to biosensing and cancer therapy applications.

Over the past few decades, nanotechnology has developed rapidly. Various nanomaterials have been gradually applied in different fields. As a kind of two-dimensional (2D) layered nanomaterial with a graphene-like structure, molybdenum disulfide (MoS2) nanosheets have broad research prospects in the fields of tumor photothermal therapy, biosensors and other biomedical fields because of their unique band gap structure and physical, chemical and optical properties. In this paper, the latest research progress on MoS2 is briefly summarized. Several commonly used exfoliation methods for the preparation of MoS2 nanosheets are reviewed based on the studies in the past five years. Additionally, the current research status of MoS2 nanosheets in the field of biomedicine is introduced. At the end of this review, a brief overview of the limitations of MoS2 research and its future prospects in the field of biomedicine is also provided.
