Electrochemical Sensor Development for Biosensing Applications

Join a cutting-edge project focused on developing advanced electrochemical sensors for rapid, highly sensitive, and cost-effective detection of target biomarkers in biological samples such as blood, saliva, or urine. Leveraging nanomaterial-based electrode modifications including 2D materials, and new materials formation and synthesis, this research will produce portable sensing platforms capable of delivering laboratory-grade analytical performance in minutes. These systems will be adaptable for a broad range of applications, from point-of-care medical diagnostics to environmental pollutant detection and food safety monitoring. As a PhD researcher, you will work at the dynamic intersection of nanotechnology, analytical chemistry, materials science, and biomedical engineering. Your role will involve designing high-performance electrode interfaces with selective biorecognition layers (antibodies, aptamers, or molecularly imprinted polymers), optimising electrochemical detection techniques such as differential pulse voltammetry (DPV) and electrochemical impedance spectroscopy (EIS), and integrating the sensors into microcontroller-driven portable systems with wireless data transfer capabilities. You will gain comprehensive hands-on experience in sensor fabrication (screen-printing, thin-film deposition, microfabrication), surface functionalisation, electrochemical characterisation, signal processing, and device prototyping. Collaboration with interdisciplinary teams including engineers, chemists, and healthcare professionals will provide valuable insight into translating laboratory prototypes into commercially viable, field-deployable biosensing solutions. Your work will push the boundaries of next-generation biosensing technology, enabling faster, more accessible, and more reliable detection platforms that address global challenges in healthcare, environmental protection, and food security.
