Abstract

The use of nanotechnology-derived products in the development of sensors and analytical measurement methodologies has increased significantly over the past decade. Nano-based sensing approaches include the use of nanoparticles (NPs) and nanostructures to enhance sensitivity and selectivity, design new detection schemes, improve sample preparation and increase portability. This review summarizes recent advancements in the design and development of NP-based sensors for assessing food safety. The most common types of NPs used to fabricate sensors for detection of food contaminants are discussed. Selected examples of NP-based detection schemes with colorimetric and electrochemical detection are provided with focus on sensors for the detection of chemical and biological contaminants including pesticides, heavy metals, bacterial pathogens and natural toxins. Current trends in the development of low-cost portable NP-based technology for rapid assessment of food safety as well as challenges for practical implementation and future research directions are discussed.

摘要

在过去十年中，纳米技术衍生产品在传感器和分析测量方法开发中的应用显著增加。基于纳米的传感方法包括使用纳米颗粒（NPs）和纳米结构来提高灵敏度和选择性、设计新的检测方案、改进样品制备并提高便携性。本综述总结了用于评估食品安全的基于纳米颗粒的传感器在设计和开发方面的最新进展。讨论了用于制造检测食品污染物传感器的最常见类型的纳米颗粒。提供了基于纳米颗粒的比色和电化学检测方案的选定示例，重点是用于检测化学和生物污染物（包括农药、重金属、细菌病原体和天然毒素）的传感器。讨论了用于快速评估食品安全的低成本便携式基于纳米颗粒技术的当前发展趋势以及实际实施面临的挑战和未来研究方向。
