Abstract

We provide a state-of-the-art review of the main strategies for the enhancement of analytical performance of sensors using nanomaterials, particularly nanowires and carbon-based materials. We emphasize the way to overcome the problem of device-to-device variation. We discuss the study of the influence of nanomaterial characteristics, sensor dimensions and operational conditions on sensing performance, and the application of appropriate calibration models.

Keywords: Analytical performance; Calibration; Carbon nanotube (CNT); Device fabrication; Device-to-device variation; Graphene; Nanomaterial; Nanowire (NW); Operational condition; Sensor.
