Applications of Graphene and Graphene Oxide as Versatile Sensors: A Brief Review
Unknown authors
Abstract
Graphene is one of the well-known allotropes of carbon and is regarded among the most significant substances of the modern era, having substantially influenced every field of research and now entering the commercial sector. It has earned popularity among researchers owing to some of its special qualities, such as excellent thermal and electrical conductivity. Thus it can be used to make electrical or strain sensors to sense toxic gasses. After the oxidation of graphene through different processes, graphene oxide is formed. As a direct consequence of the existence of oxygenated functional groups, they can also act as gas sensors, biosensors, and electrochemical sensors. This mini-review ruminates the respective implications of graphene and GO as electrical, electrochemical strain, various gas sensors, surface stress sensors, selectivity, and efficiency, along with their advantages and limitations.
