Carbon nanotube CNTs-electrochemical biosensors

Another recent topic in detection of OP compounds based on ChE-modified biosensors is to use carbon nanotubes (CNTs) as an electrode modifier. CNTs are known to exhibit excellent electrochemical properties originating from high catalytic activity of edge-plane-like graphite sites at CNT ends and a large effective surface area. Lin et al. (2004) have reported that stable CNT-modified glassy carbon (GC) electrodes can be prepared by coating the surface of GC electrode with a suspension of CNT and can be used for sensitive determination of thiocholine (Liu etal,... 

There is an enormous variety of nanomaterials that can potentially be employed in biosensor architectures. The most prominent among them are metal nanoparticles [304], quantum dots [308], and carbon nanotubes [309-311]. AH of them have been employed in biosensors though not necessarily exclusively electrochemical biosensors. Quantum dots (QDs) offer unique absorption properties making them highly suitable for the construction of biosensors with optical readout. The most diverse electrochemical nanobiosensors are, however, obtained from carbon nanotubes (CNTs) which offer a wide range of different apphcations.

There has been an exploration of interest applying carbon nanomaterials [25-28] (particularly carbon nanotube (CNT) and graphene) into the development of electrochemical biosensor. CNT-and graphene-modified electrodes both have...
