This book focuses on the variety of emerging multi-functional materials and biomarkers involved in monitoring major disorders and diseases using disposable electrodes. The specificity of these sensors improves with incorporation of nanocomposites, hybrids or coating with conductive materials. These electrochemical sensors designed with disposable electrodes are modified with various biomarkers, aptamers or specific antibodies for the detection of targeted diseases or disorders. Aimed at academic and research institutes at both the graduate and postgraduate level, the book will be of interest to the healthcare industries.
