Graphene-Based Electrochemical Sensors and Carbon Nanocomposites
This community develops carbon-based nanomaterials, primarily graphene and carbon nanotubes, to create highly sensitive electrodes for detecting specific chemical and biological targets. The work focuses on modifying these carbon structures to enhance their ability to sense substances like glucose, uric acid, and pharmaceutical compounds.
The research centers on synthesizing graphene oxide, reduced graphene, and carbon nanotubes, then integrating them with metal nanoparticles (such as gold, copper, and silver) or metal oxides to form composite electrodes. These materials are applied in electrochemical sensing platforms for the determination of analytes including hydrogen peroxide, ascorbic acid, and various drugs. Methods include the modification of glassy carbon and carbon paste electrodes, as well as the development of molecularly imprinted polymers for selective detection. The recurring themes are the enhancement of sensitivity and the creation of stable, functionalized carbon surfaces for analytical chemistry applications.
Carbon research accounts for the largest share of this community's output, representing 8.0% of all tracked carbon research and comprising 13,405 papers. Gold and nitrogen research follow, with the community contributing 2.1% and 1.0% of their respective total research volumes.
The community comprises 47,844 papers, with the highest publication volume in the journals Carbon, Microchemical Journal, and Electrochimica Acta.
Recent work continues to focus on the development of next-generation chemical sensors and biosensors, including specific applications for detecting anti-inflammatory drugs and antibiotics, as well as the creation of flexible humidity sensors and corrosion-resistant coatings using graphene-based nanocomposites.
