Recent Advances in Carbon Nanotubes Based Biosensors (original) (raw)

Carbon nanotubes (CNTs) have recently aroused worldwide interest. This has been attributed to the combination of structure, size and morphology of CNTs resulting in their reasonable surface and mechanical properties, semi-conducting and metallic properties. We discuss recent developments relating to the methods and techniques that use carbon nanotubes as transducers and mediators for fabrication of biosensors. Besides this, attempts have been made to describe in brief the preparation, characterization and applications of nano-materials to both health care diagnostics and environmental biosensing.
