This study used surface imprinting polymerization to synthesize molecularly imprinted polymer on the surface of PAF-45 material (PAF-45@MIP). SEM, FT-IR, static and kinetic adsorption experiments were adopted to investigate the morphology and properties of the MIP. The results showed that the PAF-45@MIP could rapidly absorb histamine with a high adsorption capacity. Using PAF-45@MIP as a biomimetic antibody and Pt nanozyme as a marker, a novel direct competitive biomimetic immunoassay (BIA) method for rapidly detecting histamine in foods was developed. Under optimal conditions, the limit of detection and sensitivity of the BIA method were 0.128 and 8.306 mg/L, respectively. Vinegar spiked with histamine was determined using the BIA method with recoveries ranging from 81.50% to 90.38%. The BIA method was also applied to determine histamine in dried shrimp and soy sauce samples, the results correlating well with those obtained using high-performance liquid chromatography.

“…A metabolite of pyrethroid class, 3-phenoxybenzaldehyde (3-PBD), can be oxidized to 3-phenoxybenzoic acid leading to color fading of potassium permanganate. Inspired by this phenomenon, Ye et al [ 188 ] developed a MIP for the detection of 3-PBD. The MIP layer was coated on the surface of monodispersed silica nanoparticles via sol-gel process with APTES and phenyltrimethoxysilane (PTES) as monomers.…”

This is a review of recent affinity-based approaches that detect pesticides in food. The importance of the quantification and monitoring of pesticides is firstly discussed, followed by a description of the different approaches reported in the literature. The different sensing approaches are reported according to the different recognition element used: antibodies, aptamers, or molecularly imprinted polymers. Schemes of detection and the main features of the assays are reported and commented upon. The large number of affinity sensors recently developed and tested on real samples demonstrate that this approach is ready to be validated to monitor the amount of pesticides used in food commodities.

“…Rather than coupling a MIP receptor layer to a transducer, a MIP can be further modified to exhibit effects that can be observed by the naked eye. A diverse array of systems have achieved this ability using fluorophores, dye molecules and nanoparticles to create visually identifiable assays for a host of molecules [ [64] , [65] , [66] ]. This version of MIP based analysis is aimed towards semi-quantitative / qualitative analysis, offering the capabilities of in the field-testing.…”

Highlights The review aims to summarize recent commercially interesting innovations in MIP-based sensor design. In addition to sensors, commercially viable assays based on MIPs are analysed and recent advances are summarized and discussed. The review also analyses how commercial MIP companies could contribute to a next step in the commercialization of MIP-based detection systems. The review contains a critical analysis and discussion on MIP-based sensors and assay commercialization as well as an outlook/recommendation for the future.
