Contaminant sensors: nanosensors, an efficient alarm for food pathogen detection

摘要: Food regulatory agencies have established strict control programs to avoid pathogen contamination through the food chain. Thus, a large number of samples need be rapidly and efficiently analyzed with simple operating procedure. According these requirements, detection methods rapidity, efficiency, high sample throughput, on-site analytical strategies been widely developed. Especially, nanotechnology-based method, called nanosensor, is one effective used as an “efficient alarm” promptly detect risk by pathogens in various foods. Additionally, nanosensors, such enzyme-, immuno-, microbial-, DNA-sensors higher potential further develop apply real-time monitoring devices improve safety system. This chapter provides comprehensive review current developments application nanotechnology on contaminants, focusing specifically monitoring. The includes (1) brief overview significant foodborne their key properties relation detection, (2) discussion nanosensors/assays developed for or which include details types, method applications, well future status methods.
