Carbon-Based Electrochemical Sensors for Analytical Detection
This community develops modified carbon electrodes and nanocomposites to detect specific chemical compounds, ranging from biological markers like glucose and dopamine to pharmaceuticals and environmental contaminants.
The work centers on engineering electrode surfaces using graphene oxide, reduced graphene, and carbon nanotubes to enhance sensitivity and selectivity. Recurring applications include the non-enzymatic determination of glucose, the simultaneous detection of uric acid and ascorbic acid, and the analysis of dopamine. The community also frequently employs molecularly imprinted polymers and gold nanoparticles to create selective recognition sites for drugs such as chloramphenicol and pesticides like methyl parathion. Methods rely heavily on voltammetric techniques to achieve highly sensitive and selective detection in complex matrices, including food samples and biological fluids.
The largest share of the community's output is found in carbon research, accounting for 1.5% of all carbon research, and 12,758 papers here. Gold research contributes the second-largest share at 1.6%, with 2,989 papers.
The community comprises 27,420 papers, publishing most frequently in Microchemical Journal, Electrochimica Acta, and Electroanalysis. Recent work continues to focus on novel nanocomposite modifiers, such as metal-organic framework derivatives and MXene composites, for the ultrasensitive detection of specific pharmaceuticals, pesticides, and food additives.
