Electrochemical Biosensors and Carbon Nanomaterials for Analytical Detection
This community develops electrochemical sensors and biosensors using carbon-based nanomaterials to detect specific chemical, biological, and pharmaceutical targets with high sensitivity.
The work centers on modifying electrodes with graphene oxide, reduced graphene, carbon nanotubes, and gold nanoparticles to enhance the detection of analytes such as glucose, uric acid, dopamine, and hydrogen peroxide. Recurring methods include voltammetry, impedance spectroscopy, and the use of molecularly imprinted polymers or aptamers for selective recognition. Applications span clinical diagnostics, food safety monitoring for pathogens and contaminants, and environmental analysis. The research frequently employs glassy carbon, carbon paste, and screen-printed electrodes as substrates, integrating these with nanocomposites to improve signal-to-noise ratios and lower detection limits for trace-level analysis in complex matrices.
The largest share of the community's output is found in carbon research, accounting for 2.1% of all carbon research, and 18,838 papers here. Gold research contributes the second-largest share at 2.7%, with 5,576 papers in this group.
The community comprises 41,457 papers, publishing primarily in Biosensors and Bioelectronics, Microchemical Journal, and Sensors and Actuators B Chemical.
Recent work focuses on integrating artificial intelligence with biosensors for foodborne pathogen detection, developing wearable aptamer-based sensors for continuous in vivo biomarker monitoring, and utilizing graphene-based platforms for next-generation diagnostic technologies.
