Carbon Nanotubes: Advances, Integration and Applications to Printable Electrode-Based Biosensors

Abstract

The development of novel analytical techniques for biosensor application has been an area of intense research efforts in the past decade and, in a fi eld where the demand for rapid and cost-effective analyses is high, the use of screen-printed electrodes as opposed to conventional macroelectrodes can effectively satisfy these demands. With advancements in nanotechnology, the use of nanomaterials in biosensors has also added another level of customizability and sensitivity. In this chapter, we described the use of carbon nanotubes in printable electrode-based biosensors for label-free detection approaches for the detection of environmental contaminants and biologically relevant substrates. A discussion of past developments and recent advancements will highlight the broad range of experimental designs suitable for biosensing applications. With continual innovation in this fi eld, it is expected that screen-printing technology will come to the fore in biosensing technology and progress successfully to overcome fundamental challenges in the biosensor fi eld.
