- Abstract
- As the global population increases tremendously, it drives the infectious disease rate upward. One vital cause of infectious disease is due to harmful pathogens that reside in water and food; a majority among them are transmittable from person to person. There is a huge responsibility in the hands of researchers and doctors to develop effective diagnostic techniques to detect and identify human pathogens (e.g., bacteria, fungi, virus). The conventional techniques developed are culture-based or count-based methods, polymerase chain reaction (PCR), and enzyme-linked immunosorbent assay (ELISA). None of these techniques satisfy robust detection of pathogens. Therefore, there is a remarkable demand for developing a distinguished technique to detect human pathogens. The field of nanotechnology-based biosensors emerged in recent years that satisfies the requirements of pathogen detection, such as rapidity, specificity, selectivity, etc. Various sensing technologies were introduced. Among them, nanomaterial-based optical sensors comprising colorimetric, plasmonic, and forster resonance energy transfer (FRET)-based sensors played a major role in effective detection of pathogens using remarkable nanoparticles such as gold and silver nanoparticles (AuNPs, AgNPs) and fluorescent quantum dots (QDs). A detailed view of nanomaterials, optical techniques, and commercialized products are presented in this chapter. © 2021 Elsevier Inc.
