Graphene based Materials for Bioelectronics and Healthcare

Abstract

In the last decade, graphene based materials (GBMs) have received special interest in physical sciences owing to their unique material properties at nanoscale. Extraction of two-dimensional lattice forms of carbon has allowed study of new physical phenomena at the molecular scales and allowing further miniaturization in electronics, which have tremendous implications for future technologies. Development of high-performance bioelectronics platforms is one such area where the use of GBMs is expected to yield cutting-edge sensor platforms with far reaching consequences for the advancement of life sciences and healthcare. This chapter provides an overview of how GBMs, when used as electrical transducers, are enabling very attractive functionalities towards new-age bioelectronics solutions. In doing so, this a special focus is given to GBMs produced via chemical routes for realization of devices, surface functionalization, and related transduction approaches. Finally, the chapter evaluates their role in bioelectronics based on relevant material properties, current impact and critical challenges blocking their way towards real healthcare applications.
