Electroanalytical methods are beneficial in investigating the electrochemical
characteristics of chemicals and macromolecules. The innovation of electrochemical
sensors has been of tremendous interest owing to their high sensitivity, fast analysis
and capability to analyse intricate samples; these properties make electrochemistry
significant for its use in medical applications, especially in disease detection. The
appropriate target analytes must be identified to recognize any diseases by
electrochemical techniques and their interplay with biological cells needs to be
investigated. In this chapter, we have explained an electrochemical approach and
techniques for several disease detection.
Keywords: Biosensors, Disease detection, Electrochemical sensors, Voltammetry.
