Electrochemical biosensors depend on detecting biomarkers at increasingly lower concentrations (often in the femtogram-per-millilitre range). Achieving this level of sensitivity begins with the material properties of the electrode. Traditional nanomaterials like CVD graphene, CNTs and noble metals can offer strong performance, but often fall short on reproducibility, scalability and batch-to-batch consistency in manufacturing.
Recent advances in carbon nanomaterials are solving this problem. By combining high surface area, excellent conductivity and tunable surface chemistry with reliable large-scale production, they offer a path to ultra-sensitive, commercially viable biosensors. These materials are now reaching detection limits once thought to be restricted to research labs without the trade-offs.
