Rapid and accurate identification of pathogens has always been challenging. There are a number of methods for the detection of pathogens, but still they face critical challenges. In general, rapidity, sensitivity, and accuracy are the important criteria that limit the applicability of classical methods. Nanomaterials-based biosensors have been proven to be effective for the early and accurate quantification of pathogens. Interactions between target pathogen and nanomaterials are very important, as they provide a measurable signal in biosensors. Nanobiosensors are effective in detecting pathogenic bacteria in various samples, including food, water, blood, and other matrices. In this chapter, we intend to discuss the existence and importance of electrochemical-based biosensors for quantification.
