Abstract

In water disinfection and treatment, rapid detection and monitoring of pathogens such as bacteria and viruses, as important water quality indices, are of prime importance. On the other hand, continuous monitoring and detection of pathogens have encountered the problems such as low concentration of bacteria and viruses in water, low sensitivity of the conventional detection methods, complex sample matrices and insufficient selectivity of the conventional methods, and inability of these methods in fast and cheap detection and continuous monitoring of pathogens. These indicate the importance of considering new sciences and technologies in fabrication of biosensors in order to achieve higher sensitivity, response rapidity, and selectivity. In this paper, briefly, new nanoscience approach and application of nanostructured materials in design and fabrication of nanobiosensors in order to detecting and monitoring of bacteria and viruses in water have been introduced and some examples of the applications of nanobiosensors have been also presented.
