Graphene-based Nanocomposites for DNA Sensing

With the advent of cutting-edge technologies in the field of biotechnology, more advanced biosensors with enhanced characteristics and chemical structures have been developed for biosensing purposes. In this work, graphene and its derivatives have been introduced as a compound with great potential for employment in diverse biosensors due to its remarkable chemical and mechanical properties such as high conductivity, chemical and mechanical stability, extended surface area, applicable porosity with sheet-like stable structure, and modifiability. Furthermore, diverse techniques for the fabrication of graphene-based biosensors such as fluorescent biosensors, electrochemical biosensors, and surface plasmon resonance biosensors have been investigated for DNA sensing.
