Abstract
Advanced nanomaterials indubitably represent one of the most propitious class of new materials due to their intriguing optical, electronic and redox properties. The incredible progress achieved in this research area has been propelled by the development of novel synthetic procedures owing to the emergence of nanotechnology and by the wide range of applications. These nanostructured materials possess high surface area, biocompatibility, nontoxicity and charge-sensitive conductance which have led to the development of simple, rapid, highly sensitive, inexpensive and portable electrochemical genosensors. This review accentuates on the development and validation of various advanced nanomaterials based electrochemical genosensors that utilize unique properties of nanomaterials for signal transduction purpose or as an electroactive species for direct detection of analyte. The intent is to highlight the recent progress on highly sensitive and flexible nanostructured material based electrochemical genosensors that have the potential to be developed as the next generation field-deployable analytical tools.
Keywords: Electrochemical biosensors, genosensors, nanomaterial based genosensors, DNA based biosensors, carbon nano tube based biosensors, nanomaterials.
