Abstract

Most electrical sensor and biosensors elements require reliable transducing elements to convert small potential changes into easy to read out current signals. Offering inherent signal magnification and being operable in many relevant environments field-effect transistors (FETs) are the element of choice in may cases. In particular using electrolyte gating numerus sensors and biosensors have been realized in aqueous environments. Over the past yeas electrolyte gated FETs have been fabricated using a variety of semiconducting materials including graphene, ZnO as well as conjugated molecules and polymers. In particular using conducting polymers top performing devices have been achieved. Here we present an approach to use a transition metal dichalcogenide (TMDCs) based monolayer device. Using MoS2 monolayers we show that such electrolyte gated devices may be regarded as very promising future transducing elements for sensor and biosensor applications.
