Electrochemical Detection Techniques for Cholesterol Biosensing
Summary
Electrochemical detection of cholesterol relies on the conversion of biochemical interactions into measurable electrical signals. Central to many designs is the enzyme cholesterol oxidase, which catalyses the oxidation of cholesterol to generate hydrogen peroxide or other redox‐active species. Amperometric sensors quantify the current produced at a fixed potential, while voltammetric methods record current as a function of applied voltage, and impedimetric approaches monitor changes in interfacial resistance. Recent advances exploit nanostructured materials—such as carbon nanotubes, gold nanoparticles and quantum dots—to increase electrode surface area, enhance electron transfer and improve enzyme immobilisation. Nonenzymatic platforms have also emerged, using catalytic metal oxides or doped carbon architectures to oxidise cholesterol directly. These innovations aim to deliver high sensitivity, low limits of detection and rapid response times, suitable for point-of-care diagnostics. The integration of microfabrication and flexible substrates further supports miniaturised, disposable formats. Ongoing efforts focus on balancing analytical performance with stability, selectivity against biological interferents and cost-effective fabrication, addressing the global demand for accessible cardiovascular risk screening tools.
