Ali R. Jalalvand, Mohammad Mehdi Karami
Abstract
The rapid advancements in nanotechnology have significantly enhanced the capabilities of electrochemical sensors, particularly in the realm of medical diagnostics. This review article explores the integration of nanomaterials such as nanoparticles, nanowires, nanotubes, and graphene in electrochemical sensors and their transformative impact on disease detection and health monitoring. Nanotechnology-enhanced sensors offer remarkable improvements in sensitivity, specificity, miniaturization, and making them ideal for point-of-care testing and real-time analysis. This review article provides a comprehensive information about the types and mechanisms of electrochemical sensors, the unique properties of nanomaterials that enhance sensor performance, and the diverse medical applications ranging from biomarker detection to pathogen identification. Despite the promising benefits, several challenges including technical, regulatory, and market barriers are discussed alongside potential strategies to overcome these hurdles. The ongoing research and development in this field promise to revolutionize medical diagnostics by providing rapid, accurate, and accessible testing solutions ultimately improving patient outcomes and healthcare efficiency.
