Carbon Nanomaterials for Electrochemical and Optical Sensing
This community develops carbon-based nanomaterials, such as graphene oxide and carbon dots, to create highly sensitive sensors for detecting specific chemical compounds, biological markers, and environmental contaminants.
The research focuses on synthesizing and modifying carbon structures—including graphene, carbon nanotubes, and nitrogen-doped carbon—to enhance their performance as electrodes or fluorescent probes. Recurring applications include the electrochemical detection of analytes like uric acid, ascorbic acid, and hydrogen peroxide, as well as the selective identification of pharmaceuticals and food additives. Methods frequently involve the creation of nanocomposites, the use of molecularly imprinted polymers for selectivity, and the integration of metal nanoparticles like gold or silver to boost signal response. The work emphasizes achieving high sensitivity and selectivity in complex matrices, often through green synthesis techniques and the development of stable, functional sensing platforms for point-of-care or industrial analysis.
The largest share of the community's output is found in carbon research, accounting for 7.9% of all carbon research, with 9,203 papers in this group. It also represents a significant portion of cadmium research (4.0%) and gold research (3.1%).
The community comprises 49,336 papers, publishing most frequently in Microchemical Journal, Carbon, and Sensors and Actuators B Chemical.
Recent work continues to explore the application of these materials in food safety and healthcare diagnostics, with specific studies on detecting residues like ofloxacin in food and developing graphene-based biosensors for diagnostic technologies.
