Enzyme-free sugar sensing in microfluidic channels with an affinity-based single-wall carbon nanotube sensor.

Abstract

We present a novel nonenzymatic carbon nanotube sensor integrated in a microfluidic channel for the detection of sugars. The sensor is assembled as a liquid-gated field-effect transistor, with the transistor channel composed of 1 to 10 nanotubes, which are controllably functionalized with boronic acid receptors. The devices show sensitivity to glucose in a… (More)
