Special Issue Information
Dear Colleagues,
Benefiting from the distinct transduction property, graphene has been viewed as one of the most promising materials for the fabrication of rapid and sensitive sensors for biological quantity detection.
The high-quality and low-cost of graphene have been developed very quickly in the past few years, which has paved the way for the development of many different biosensors. However, research into grephene-based sensors are still in their infancy and far from real applications due to the difficulties in fabricating devices with good uniformity and reproducibility. Therefore, more effort needs to be paid on the following aspects of this field. Firstly, it is critical to have a better understanding of interactions between graphene and varieties of interfaces, molecules, and cells. Secondly, the miniaturization and functionalization of graphene-based sensors should be investigated to facilitate the fabrication of biosensors in arrays that can be used for highly sensitive, selective, and high-throughput sensing. Thirdly, specific detections of the biological sensors are of critical importance to their practical applications. The reported sensors are normally tested in strictly controlled conditions while many interference factors widely existing in the real environment have not been considered. So, the selectivity and stability of the graphene-based sensors need to be characterized and optimized in a real-time environment analyzing and in vitro or in vivo biological sensing. Moreover, some unexpected results may come from the impurities or defects of graphene. So, the techniques for synthesizing high-quality graphene need to be developed. Significant efforts should be devoted to developing facile strategies for controllable, reproducible, and scalable synthesis and the functionalization of graphene with defined properties.
The purpose of this Special Issue is to present the state of recent progress in this field, including the new fabrication methods of graphene, graphene-based sensors, and the various applications of graphene-based sensors. The Special Issue covers various aspects of theoretical and experimental researches related to graphene-based sensors. We welcome all the submissions relating to recent progress in graphene-based sensors.
Potential topics include, but are not limited to, the following:
Graphene in field-effect transistors for biosensors;
Graphene used for surface enhanced Raman scattering (SERS);
Graphene-based electrochemical, impedance and electrochemiluminescence biosensors;
Fluorescence biosensors based on graphene;
Graphene-based fiber optic surface plasmon resonance (SPR) for biosensors.
