ABSTRACT
Graphene-related materials possess the fascinating properties which enable their use in potential applications such as biomedical, optics, electronics, sensing and energy and metal adsorption. A nanotechnology usesful for treatment, monitoring, diagnosis and control of biological systems is called "nanomedicie". Numerous studies have been reported indicating the graphene's bioapplications in chemotherapeutics for the cancer treatment, biosensing applications for a host of medical conditions and for the differentiation and imaging of stem cells. The integration of biological components with electronics is growing field and one of the current challenges for the field of bioelectronics. This holds a great promise for developing the prostheses for injured organs. Biology and electronics may interface at three levels namely molecular, cellular and skeletal. Electrochemical sensors are, by far, the largest group of sensors and provide an especially attractive means with which to analyse the content of a biological sample due to the direct conversion of a biological recognition event to an electrical signal.
