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.

期刊介绍： Sensing and Bio-Sensing Research is an open access journal dedicated to the research, design, development, and application of bio-sensing and sensing technologies. The editors will accept research papers, reviews, field trials, and validation studies that are of significant relevance. These submissions should describe new concepts, enhance understanding of the field, or offer insights into the practical application, manufacturing, and commercialization of bio-sensing and sensing technologies. The journal covers a wide range of topics, including sensing principles and mechanisms, new materials development for transducers and recognition components, fabrication technology, and various types of sensors such as optical, electrochemical, mass-sensitive, gas, biosensors, and more. It also includes environmental, process control, and biomedical applications, signal processing, chemometrics, optoelectronic, mechanical, thermal, and magnetic sensors, as well as interface electronics. Additionally, it covers sensor systems and applications, µTAS (Micro Total Analysis Systems), development of solid-state devices for transducing physical signals, and analytical devices incorporating biological materials.
