摘要

食品安全问题与食品工业的经济发展和公众健康息息相关,已成为全球关注的一个重要问题,受到全世界越来越多的关注。高效检测技术的应用在确保食品安全方面发挥着至关重要的作用。近年来,在快速检测和家庭检测需求日益增长的推动下,POCT(床旁检测)生物传感器取得了长足的进步。纸质生物传感器已成为 POCT 生物传感器领域的一个重要类别,这主要是因为它们具有成本效益、简便和便携的特点。为了满足各种应用中日益增长的对 POCT 的需求,人们对纸基底的功能化提出了很高的要求。金属有机框架(MOF)是一种多功能多孔纳米材料,可用于制造纸基平台,大大提高检测功能和应用潜力。本研究概述了 MOF 功能化纸基生物传感器(MOF@paper)的最新发展和新兴趋势,包括各种基底、构建技术、诊断应用和机制。由于 MOF@paper 生物传感器的优越性能和多功能性,该领域在科学研究、食品安全和控制应用方面前景广阔。

Mof-mediated paper-based (bio)sensors for detecting of food and environmental pollutants: Preparation strategies and emerging applications
The issue of food safety, which is intricately related to the economic progress of the food industry and public health, has emerged as a significant global concern that is receiving increasing attention worldwide. The implementation of efficient detection technologies plays a vital role in ensuring the safety of food products. In recent years, there has been significant advancement in the progress of POCT (point-of-care testing) biosensors, driven by the increasing demand for rapid and home testing. Paper-based biosensors have emerged as a prominent category within the realm of POCT biosensors, primarily because of their cost-effectiveness, simplicity, and portability. In order to address the growing need for POCT in a variety of applications, there is a highly demanded for the functionalization of paper substrates. Metal-organic framework (MOF), a versatile porous nanomaterial, is presented in the fabrication of paper-derived platforms, meaningfully boosting the detecting feature and application potential. This study offers an overview of the latest developments and emerging trends in MOF-functionalized paper-based biosensors (MOF@paper), encompassing various kinds of substrates, construction techniques, diagnosis applications and mechanisms. Due to the superior performance and multifunctionality of MOF@paper biosensors, this area shows promising prospects in scientific research, food safety, and control applications.
