Chapter 13 - Graphene-Containing Microfluidic and Chip-Based Sensor Devices for Biomolecules

Abstract

Graphene-based microfluidic devices can be useful for biosensors and for studying biological systems owing to their comparable length scales and flow characteristics. In sensing and biosensing, the goal in microfluidics research is to develop integrated miniaturized devices capable of achieving high sensitivity and selectivity, rapid response, multiplexing, automation and allow for tests with a small sample volume. In this chapter, a description is presented of fabrication techniques of graphene and derivatives, particularly focused on their possible application in microfluidic devices. A major emphasis is placed on the challenges to reach point-of-care diagnostics, which requires considerably more extensive research as only a few graphene-related studies involving microfluidic devices are available in the literature.
