近年来，二维层状纳米材料由于其超薄结构所具有的量子尺寸效应引起了人们的极大兴趣。特别是2D二硫化钼（MoS2）作为一类具有固有有限带隙的稳定无机石墨烯类似物，在电子和光电子领域可能会补充甚至超越石墨烯。在这篇综述中，我们首先讨论了二维纳米材料的历史发展。然后，我们关注2D MoS 2，包括它的结构与性能关系、合成方法、层厚度表征以及过去五年的生物传感器应用。其中重点介绍了二维MoS2生物传感器的最新研究进展，特别是传感元件的制备、二维MoS2的作用和检测策略。最后，在总结二维MoS2及其他层状纳米材料研究现状的基础上，展望了二维MoS2生物传感器的发展前景。(C)© 2016 Elsevier B.V.版权所有。
Recently, two-dimensional (2D) layered nanomaterials have trigged intensive interest due to the intriguing physicochemical properties that stem from a quantum size effect connected with their ultra-thin structure. In particular, 2D molybdenum disulfide (MoS2), as an emerging class of stable inorganic graphene analogs with intrinsic finite bandgap, would possibly complement or even surpass graphene in electronics and optoelectronics fields. In this review, we first discuss the historical development of ultrathin 2D nanomaterials. Then, we are concerned with 2D MoS2 including its structure-property relationships, synthesis methods, characterization for the layer thickness, and biosensor applications over the past five years. Thereinto, we are highlighting recent advances in 2D MoS2-based biosensors, especially emphasize the preparation of sensing elements, roles of 2D MoS2, and assay strategies. Finally, on the basis of the current achievements on 2D MoS2 and other ultrathin layered nanomaterials, perspectives on the challenges and opportunities for the exploration of 2D MoS2-based biosensors are put forward.
