Emerging Biosensor Platforms for the Assessment of Water-Borne Pathogens

Abstract

Pathogens are key contaminants in water responsible for the generation of various water-borne diseases, and includes viruses, fungi, bacteria, and protozoan parasites. The pathogenic effects of these species in water depend on their shape, size, composition, and structure. The resulting water-borne diseases are a serious threat to environment including humans and animals, and are directly responsible for environmental deterioration and pollution. The potential presence of these pathogens requires sensitive, powerful, efficient, and ideally real-time monitoring methods for their reproducible quantification. Conventional methods for pathogen detection mainly rely on time-consuming enrichment steps followed by biochemical identification strategies, which require assay times ranging from 24 h to up to a week. In recent years, significant efforts have been made towards the development of biosensing technologies enabling rapid and close-to-real-time detection of water-borne pathogens. This review summarizes recent developments on biosensors and sensing systems based on a variety of transducer technologies for water quality monitoring with specific focus on rapid pathogen detection.
