“…Because they are intrinsically toxic, regulatory agencies (such as WHO, FAO, and EPA) set acceptable maximum limits of pesticide residue to protect consumers from their adverse effects [ 90 ]. Detection of pesticide residues in food matrices has been demonstrated in multiple paper sensors [ 91 , 92 , 93 , 94 ], with a couple of paper sensors using electrochemical techniques [ 95 ]. Although the majority of reported e-PADs have only interrogated pesticides in standard solutions and/or environmental samples, the sensors are also promising for pesticide analysis in food, by integrating suitable sample preparation techniques.…”

Nowadays, foodborne pathogens and other food contaminants are among the major contributors to human illnesses and even deaths worldwide. There is a growing need for improvements in food safety globally. However, it is a challenge to detect and identify these harmful analytes in a rapid, sensitive, portable, and user-friendly manner. Recently, researchers have paid attention to the development of paper-based electrochemical biosensors due to their features and promising potential for food safety analysis. The use of paper in electrochemical biosensors offers several advantages such as device miniaturization, low sample consumption, inexpensive mass production, capillary force-driven fluid flow, and capability to store reagents within the pores of the paper substrate. Various paper-based electrochemical biosensors have been developed to enable the detection of foodborne pathogens and other contaminants that pose health hazards to humans. In this review, we discussed several aspects of the biosensors including different device designs (e.g., 2D and 3D devices), fabrication techniques, and electrode modification approaches that are often optimized to generate measurable signals for sensitive detection of analytes. The utilization of different nanomaterials for the modification of electrode surface to improve the detection of analytes via enzyme-, antigen/antibody-, DNA-, aptamer-, and cell-based bioassays is also described. Next, we discussed the current applications of the sensors to detect food contaminants such as foodborne pathogens, pesticides, veterinary drug residues, allergens, and heavy metals. Most of the electrochemical paper analytical devices (e-PADs) reviewed are small and portable, and therefore are suitable for field applications. Lastly, e-PADs are an excellent platform for food safety analysis owing to their user-friendliness, low cost, sensitivity, and a high potential for customization to meet certain analytical needs

“…Wang et al [ 54 ] successfully developed a novel MIP-grafted paper-based multi-disk micro-disk plate and performed the high-throughput chemiluminescence detection of 2,4-dichlorophenoxyacetic acid. Vodova et al [ 55 ] combined UV-induced fluorescence spectroscopy and MIP–PADs to detect selected commercial pesticides (ZATO 50 WG, TITUS WG 25) from pesticide-sprayed apples and tomatoes for the first time. These new MIP paper devices are particularly suitable for the field testing of pesticide residues such as pesticides in remote areas.…”

Paper-based analytical devices (PADs) are highly effective tools due to their low cost, portability, low reagent accumulation, and ease of use. Molecularly imprinted polymers (MIP) are also extensively used as biomimetic receptors and specific adsorption materials for capturing target analytes in various complex matrices due to their excellent recognition ability and structural stability. The integration of MIP and PADs (MIP-PADs) realizes the rapid, convenient, and low-cost application of molecular-imprinting analysis technology. This review introduces the characteristics of MIP-PAD technology and discusses its application in the fields of on-site environmental analysis, food-safety monitoring, point-of-care detection, biomarker detection, and exposure assessment. The problems and future development of MIP-PAD technology in practical application are also prospected.

“…The use of MIPs in water quality control serves for in-situ monitoring of carbofuran, or organophosphorus pesticides such as diazinon in combination with other electrochemical techniques such as cyclic voltammetry or impedance measurements [41]. Other interesting analytical procedures include the coating of paper with MIPs and the use of colorimetry or fluorescence to visually observe the presence of pesticides in fruit such as tomatoes and apples [42]. Also, biosensors based on enzymes immobilization in a polymeric matrix in screenprinted electrodes are raised as real-time analytical systems for pesticides, specially dichlorvos and methylparaoxon in aqueous matrices [9].…”

A large number of annual cases of diseases and deaths related to spoiled or contaminated food, and the amount of food waste are a matter of socio-economic impact, highlighting the need for a fast, easy, cheap, available, and real-time determination of food quality and safety. To ensure this, physical and chemical food quality indicators such as humidity, temperature, gases, pH, microorganisms, pesticides, etc., should be controlled and monitored during production, transportation, storage, and consumption. In this sense, smart polymers are raised as useful tools to facilitate this task. These polymers are sensitive to variations in the microenvironment, modifying their properties and/or generating a response that can be measured. Due to their versatility, these materials can be part of the food packaging to inform the consumers or be used as a measuring tool to determine the state of the food. This chapter envisaged the concept of smart polymers, the types, and their main applications for determining food quality and ensuring food and beverage safety.
