Molecular imprinting-based ratiometric fluorescence sensors for environmental and food analysis

“…81 (C) Construction of MIP-based ratiometric fluorescent microfluidic paper chip. 117 been relatively mature. These are described in detail in section 2.…”

“…When applied to the detection of trace CAP in food, high recoveries within 98.2%-101.2%were obtained, indicating practical applicability for the rapid visual detection of CAP. Ma et al 117 constructed a MI-RFL sensor and designed a microfluidic paper chip for the rapid visual detection of difenoconazole in tomatoes. The construction process of microfluidic chips is shown in Fig.…”

Breaking the clean room barrier: exploring low-cost alternatives for microfluidic devices

“…Recent advances in surface modification techniques, such as molecular imprinting, electrochemistry, or immunoassay, have allowed precise modification of paper’s surface chemical properties, resulting in precise fluid flow control and enhanced functionality ( Cate et al, 2015 ; Boonkaew et al, 2021 ; Zhu L et al, 2022 ; Wang et al, 2023 ). These advances have led to the development of point-of-care tests with integrated detection functionalities that exhibit fluorescent, electrochemical, and microfluidic colorimetric paper chips ( Cincotto et al, 2019 ; Ma et al, 2020 ; Tran et al, 2021 ). However, paper’s weak mechanical strength restricts its application in high-pressure environments, and its vulnerability to degradation limits its use in harsh conditions ( Yetisen et al, 2013 ; Carrell et al, 2019 ).…”

Rapid Detection of Dimethoate in Soybean Samples by Microfluidic Paper Chips Based on Oil-Soluble CdSe Quantum Dots

“…However, MIPs also have some inevitable shortcomings, such as the varying degrees of template molecular residues, weak binding force, slow mass transfer rate and so on, which hampers the widespread adoption of MIPs [12]. Accordingly, references about the applications of surface molecularly imprinted polymers (SMIPs) have been emerging, especially for the detection of some common harmful substances, including but not limited to pesticides [13,14], fungal toxin. Generally, there are three types of interaction between templates and functional monomers, including covalent, non-covalent, and semi-covalent interactions, among which the non-covalent bond (including hydrogen bonding, electrostatic interaction, hydrophobic interaction, metal chelation, coordination, etc.)…”
