Electrochemical Biosensing Technologies Using Carbon Nanomaterials
Summary
Electrochemical biosensors exploit the direct conversion of biochemical interactions into measurable electrical signals. Carbon nanomaterials—including carbon nanotubes, graphene and its derivatives, carbon quantum dots and nanodiamonds—have emerged as key enabling components owing to their exceptional electrical conductivity, large surface‐to‐volume ratio and favourable biocompatibility. These properties enhance electron transfer kinetics, lower detection limits and support the immobilisation of biorecognition elements such as enzymes, antibodies or nucleic acids. Surface functionalisation strategies allow selective attachment of receptors while preserving their activity, and nanostructured architectures can be tailored to tune sensitivity, dynamic range and response time. Current platforms range from disposable test strips and wearable patches to implantable microelectrodes, addressing applications in point-of-care diagnostics, environmental monitoring, food safety and continuous health surveillance. Integration with microfluidics and wireless readouts further amplifies global accessibility and paves the way for real-time multiplexed analysis in resource-limited settings.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
