ABSTRACT
Of global concern, environmental pollution adversely affects human health and socioeconomic development. The presence of environmental contaminants, especially bacterial, viral, and parasitic pathogens and their toxins as well as chemical substances, poses serious public health concerns. Nanoparticle-based biosensors are considered as potential tools for rapid, specific, and highly sensitive detection of the analyte of interest (both biotic and abiotic contaminants). In particular, there are several limitations of conventional detection methods for water-borne pathogens due to low concentrations and interference with various enzymatic inhibitors in the environmental samples. The increase of cells to detection levels requires long incubation time. This review describes current state of biosensor nanotechnology, the advantage over conventional detection methods, and the challenges due to testing of environmental samples. The major approach is to use nanoparticles as signal reporter to increase output rather than spending time to increase cell concentrations. Trends in future development of novel detection devices and their advantages over other environmental monitoring methodologies are also discussed.

Mentions: Moreover, assays without any sample preparation have been established using innovative nanotechnological tools, leading to user-friendly platforms with rapid and reliable results [19]. As presented in Figure 1, different nanoparticles show specific optical, fluorescence, and magnetic properties, and integrations between these properties hold great promise for environmental screening. In particular, the applications of nanoparticle-based technology enable us to monitor or even improve quality of air, water, and soil. For example, silica nanoparticles are considered an appropriate choice with multiple functional abilities as to deliver antimicrobial agents for treating towards particular pathogenic microorganisms and to sense the microorganisms [20]. Therefore, this further section summarizes the impact of sensing nanotechnology on improving the current testing procedures for accurate and precise monitoring of environmental pathogens and other contaminants.
