“…However, nonspecific adsorption is inevitable for β‐CD‐based MIPs under aqueous conditions. Thereby, the imprinting efficiency and specific binding performance of pyrethroid–MIPs may be further improved if a combination of β‐CD and other kinds of functional monomers (e.g., vinyl monomer/methacrylic acid26) is taken into account for the imprinting, even in collaboration with metal ions to enhance interactions between the monomers and template molecules 42. Apart from LCT‐imprinted polymers, the use of other pyrethroid analytes of interest as templates in the preparation of corresponding β‐CD‐based MIPs and a further comparison of their cross‐selectivity need to be researched to systematically investigate the template‐dependent recognition mechanism of MIPs and thus provide reasonable guidance toward their various applications in real sample analysis.…”

Recent years have witnessed growing applications of the molecular imprinting technique for the detection of pesticide residues in environmental and food samples. In this study, molecularly imprinted polymers (MIPs) for pyrethroids, a class of popular insecticides, were synthesized by the crosslinking of β‐cyclodextrin (β‐CD) with 1,6‐hexamethylene diisocyanate (HMDI) or toluene‐2,4‐diisocyanate (TDI) in dimethyl sulfoxide, with lambda‐cyhalothrin (LCT) as a model template. Equilibrium batch‐rebinding tests were operated in different aqueous solutions. The results indicate that MIP prepared with TDI (MIP–TDI) possessed a much greater binding activity to LCT than MIP based on HMDI (MIP–HMDI), and MIP–TDI displayed a remarkably specific binding to LCT (with an imprinting factor of around 3) in an acetonitrile/water (4:7 v/v) mixture. The adsorption of LCT by MIP–TDI reached equilibrium after 3 h; this demonstrated comparatively rapid adsorption kinetics. Also, MIP–TDI could be regenerated eight times at least; this implied that the robust β‐CD polymer has the potential for practical applications. Furthermore, a cross‐selectivity study indicated that the high adsorption of LCT and its analogues by MIP–TDI in aqueous media must have been ascribed to the cooperative effects of CD inclusion interaction and stereoshape memory. This study paved the way for the use of β‐CD as a functional monomer for preparing smart artificial receptors for the efficient recognition of pyrethroids under aqueous conditions. © 2012 Wiley Periodicals, Inc.

“…In literature there are many papers devoted to the selective adsorption of polyaromatic compounds from the liquid phase by polymer sorbents obtained with the use of molecular imprinting technology [7][8][9][10]. Molecular imprinting [11] makes it possible to obtain effective selective sorbents by means of a relatively simple synthetic procedure.…”

The process of naphthalene adsorption from the gas phase by layers of core shell polymer nano particles obtained with the use of molecular imprinting methods is studied by the fluorescent analysis method. Within the pseudo second order kinetic model of sorption, data on the rate constants of fluorescence change are obtained, primary regularities of the sorption process are determined, and the presence of selective rec ognition sites in the shells of nanoparticles is proven.

SummaryHerein we present a survey of the literature covering the development of molecular imprinting science and technology over the years 2004 to 2011. In total, 3779 references to the original papers, reviews, edited volumes and monographs from this period are included, along with recently identified uncited materials from prior to 2004 which were omitted in the first instalment of this series covering the years 1930 to 2003. 1 In the presentation of the assembled references, a section presenting reviews and monographs covering the area is followed by sections describing fundamental aspects of molecular imprinting including the development of novel polymer formats. Thereafter, literature describing efforts to apply these polymeric materials to a range of application areas is presented. Current trends and areas of rapid development are discussed.2
