The evolution and developments of immunosensors for health and environmental monitoring: problems and perspectives

Abstract

This paper is an overview of the recent developments in immunosensors, which have attracted considerable attention. Immunosensors can play an important role in the improvement of public health by providing applications for which rapid detection, high sensitivity, and specificity are important, in areas such as clinical chemistry, food quality, and environmental monitoring. This review focuses on the current research in immunoassay methods based on electrochemical detection for the analysis of environmental samples or medical diagnostic methods with emphasis on recent advances, challenges and trends. Technological aspects in the development of immunosensors such as kinetics of biomolecular interaction, techniques of immobilization, simplification of assay procedures, immunointeration and catalytic studies and system miniaturization are presented
