Preparation and characterization of surface molecularly imprinted film coated on a magnetic nanocore for the fast and selective recognition of the new neonicotinoid insecticide paichongding (IPP)

Abstract

The selective recognition of IPP-MMIPs and IPP-MNIPs for four kinds of neonicotinoid insecticides, including IPP, imidacloprid, thiamethoxam and thiacloprid.

A facile molecularly imprinted electrochemical sensor based on graphene: application to the selective determination of thiamethoxam in grain

“…In order to further understand the mechanism of adsorption, adsorption isotherm models, which describe the manner in which molecules interact with the surface of the modied GCE, were developed in this study. 29 As shown in Fig. 9, the correlation coefficient of the Langmuir isotherm was 0.980, and the correlation coefficient of the Freundlich model was 0.996; both models have good tting.…”

Molecularly imprinted polymers in diagnostics: accessing analytes in biofluids

“…Recent studies have shown surface or outer layer modifications of MIPs to be a popular method of molecular imprinting, utilising specific carriers such as silica, polystyrene microspheres, quantum dots, metal–organic frameworks, magnetic nanoparticles, and carbon nanomaterials. 87,90–93 Qu et al recently used surface molecular imprinting to fabricate a highly selective MIP prepared on glucose-derived microporous carbon nanospheres for the removal of phenol (Fig. 3(b-i)), a highly toxic substance found in wastewater which can affect the cardiovascular and central nervous system.…”

Recent Advances and Future Trends in the Detection of Contaminants by Molecularly Imprinted Polymers in Food Samples

“…This is conducive for the removal and recombination of template molecules, it reduces the "embedding" phenomenon and migration resistance of template molecules, and it improves both the amount of adsorption and the MIP S mass transfer rate (Carter and Rimmer, 2004;Li et al, 2006). Commonly used carriers are polystyrene microspheres (Sonawane and Asha, 2017), silica (Wang et al, 2017), carbon nanomaterials (Dai et al, 2014), magnetic nanoparticles (Ning et al, 2017), quantum dots (Yu et al, 2017), and metal-organic frameworks (Zhang et al, 2016). The surfaces of imprinted materials are easy to control, and the molecularly imprinted sites are readily exposed to targets.…”

“…To date, more and more researchers have prepared different kinds of MIPs as adsorbents in extraction technology to obtain higher extraction recovery. The method of combining MIPs with SPE is of great significance to identify and detect the residues of agricultural veterinary drugs in real samples (Zhang et al, 2016). For example.…”
