Remote Plasma-Assisted Synthesis of Graphene for Development of Flexible Biosensors

Abstract

Due to graphene's unique 2D monolayer structure, it has been reported to have high charge carrier mobility and also high surface energy. Therefore, it is an ideal substrate for the development of label-free biosensors as it allows more biomolecules to be immobilized on the sensing surface. This would lead to enhanced sensitivity due to a greater number of binding sites available for sensing the analytes. Hence, graphene is an attractive material for the research and development of a wide variety of biosensors for healthcare and biomedical applications.
