Abstract: The atomically thin layer of molybdenum disulfide (MoS2), analogue of graphene, has stimulated exploding interests due to its direct-gap properties and potential applications in electronics. In this report, we have investigated three preparation processes towards single-layered MoS2 and developed a label-free, selective and sensitive FET based sensor for bacteria detection by using CVD grown MoS2 thin film as its sensing element. Low detection limit of 100cfu/ml was achieved. In addition, functionalization of anti-E.coli antibody on MoS2 monolayer ensured specificity of the sensor. To our best knowledge, this is the first single-layered MoS2 based electrical sensor for detection of bacteria. It provided a high throughput platform for screening of antibacterial drugs and functional studies.
