Vertically-Oriented Graphene for Sensing and Environmental Applications

摘要: As an atomic-thick layer material, graphene has a large specific surface area, high electron mobility, and sensitivity to electronic perturbations from adsorption/desorption of molecules, which are attractive properties the sensing perspective. Graphene been widely studied for applications, e.g., in biosensors gas sensors. On other hand, although shows promise miniaturized high-performance sensors, many challenges still remain low-cost large-scale fabrication sensors with reliable performance. Recently, vertically-oriented (VG) emerged as new type VG-based nanostructures have explored advance technology due VG’s unique structure properties. Using VG element, detection biomolecules (e.g., proteins, DNA, bacteria) gases NO2, NH3, H2). The shown promising features that could be used address some current technologies biomolecule detection, cost, low sensitivity/selectivity, and/or being unsuitable situ real-time detection. Due its vertical orientation conductivity, also green corona discharge ozone generation, is another important application environmental fields. In this chapter, representative introduced discussed.
