Abstract:
Nanosensors have become an indispensable tool in the food sector due to their specificity and sensitivity. The biosensor consists of a transducer coupled with a biorecognition component to transform biological signal into digital signal. Nanobiosensors have been widely used for sensing toxic chemicals such as pesticide residues and pathogenic microbes owing to their accurate sensitivity in an affordable manner, which gives more hope to the food industry on their applications. It employs nanocarriers to bind to impurities and pollutants, as well as food-borne microorganisms and their resulting toxins, such as mycotoxins. This modern technology ensures food safety in food processing industries. Nowadays, nanoparticle-immobilized sensors act as spot indicators to improve smart food packing technology. Certain types of nanobiosensors are deployed to monitor food product manufacture till packaging and to check the freshness of the product till spoilage identification. They are mainly using enzyme catalysts, which are highly sensitive to extreme environmental conditions. As a result, there is a greater evaluation requirement in nanosensor technology to adopt any temperature, pH, or other difficult parameters. Its stability, while in contact with food substrates, is another criterion that needs to be regularized. Within this framework, this review delves into the latest developments in nanobiosensors and the obstacles encountered during their use across different food industries.
摘要:
纳米传感器由于其特异性和灵敏度已成为食品行业不可或缺的工具。生物传感器由与生物识别组件耦合的换能器组成,以将生物信号转换为数字信号。纳米生物传感器由于其准确的灵敏度,以负担得起的方式被广泛用于感测有毒化学物质,如农药残留和病原微生物,这给食品工业的应用带来了更多的希望。它使用纳米载体来结合杂质和污染物,以及食源性微生物和它们产生的毒素,如霉菌毒素。这种现代技术确保了食品加工行业的食品安全。如今,纳米粒子固定传感器作为斑点指示器,以改善智能食品包装技术。部署某些类型的纳米生物传感器以监测食品生产直到包装,并检查产品的新鲜度直到腐败识别。他们主要使用酶催化剂,对极端环境条件高度敏感。因此,纳米传感器技术对采用任何温度都有更高的评估要求,pH值,或其他困难的参数。其稳定性,与食品基质接触时,是另一个需要规范化的标准。在这个框架内,这篇综述探讨了纳米生物传感器的最新发展以及在不同食品工业中使用纳米生物传感器时遇到的障碍。
