Nanobio Materials and Devices in Nanobiotechnology

Nanobio materials are at the leading edge of the rapidly developing field of nanobiotechnology. Their unique sizedependent properties make these materials superior and essential in many areas of human activity. Examples include Fluorescent biological labels, cancer therapy, drug and gene delivery, protein detection and separation and purification of biological molecules and cells etc. However Nanobio materials can also be applied to build novel electronic devices. For instance, the unique properties of carbon-nanotubes (CNT) have paved the way to new and improved sensing devices in general and electrochemical biosensor in particular. The greatly enhanced reactivity of hydrogen peroxide and NADH at CNT-modified electrodes makes these nanomaterials extremely attractive for numerous oxidase- and dehydrogenase-based amperometric biosensors. This review tries to summarise the most recent developments in the field of applied nanobio materials, in first step. Secondly, common designs of CNT-based biosensors are discussed along with practical examples of such devices
