Boronic acid functionalized CNT-based FET sensor for the detection of glucose. (a) Schematic of the FET sensors and the illustration of binding of glucose to a CNT functionalized with pyrene-1-boronic acid. Bound glucose forms a boronate anion complex. (b) Sensing response as a function of the concentration of glucose (blue circles). Control experiments included responses from unfunctionalized devices to glucose (red squares), responses from functionalized devices to lactose (black triangles), and null response of functionalized devices to DI water.
