Nowadays, detection of a single-base polymorphism is thought to be the key for diagnosis of about 400 genetic diseases and, realization of personalized medicine in order to develop therapeutics.The other hand, the integration of new emerging nanomaterials(graphene)with sensors and devices have revealed an enormous potential for the future application of highly sensitive and selective DNA biosensors.All these approaches open up the routes for genetic researchers to understand the progression and early screening of diseases, or forensic analysis by tailoring the electrical properties of...
