“…1189 Thin-layer composite MIP membranes appear to have some potential for solid-phase extraction as shown by extraction of the triazine herbicides desmetryn on a desmetryn-MIP membrane 851,853 and terbumeton on a terbumeton-MIP membrane. 1190 The extraction of active components from traditional Chinese herb medicines include flavonoids from gingko leaves, 1191 inhibitors of epidermal growth factor receptor from Caragana jubata 1192 and matrine from the medicinal plant Sophora flavescens. 1193 A related example is the extraction of ceramides from yeast.…”

“…A similar approach was used to produce terbumeton-imprinted layers on polyvinylidene fluoride membranes and improved selectivities were observed. 1190 Ulbricht and Kochkodan then used a similar approach with an alternative photoinitiator, benzoin ethyl ether, to develop desmetryn-selective membranes. 853,1366,1367 Hilal and Kochkodan grafted layers of cAMP-imprinted MAA-TRIM co-polymer onto polyethersulfone microfiltration membranes using BEE as photoinitiator.…”

Over 1450 references to original papers, reviews and monographs have herein been collected to document the development of molecular imprinting science and technology from the serendipitous discovery of Polyakov in 1931 to recent attempts to implement and understand the principles underlying the technique and its use in a range of application areas. In the presentation of the assembled references, a section presenting reviews and monographs covering the area is followed by papers dealing with fundamental aspects of molecular imprinting and the development of novel polymer formats. Thereafter, literature describing attempts to apply these polymeric materials to a range of application areas is presented.

“…Foi avaliada a capacidade das membranas de adsorverem a terbumetona, sendo que as membranas impressas mostraram maior capacidade de adsorção para a terbumetona do que para compostos similares (atrazina, desmetrina e metribuzina). A alta afinidade destas membranas sintéticas associada ao baixo custo do preparo delas mostraram que elas poderiam ser empregadas com sucesso em procedimentos de separação como SPE [139] . Em outro estudo, Pap et al descreveram um método de pré-tratamento de amostra em dois estágios para aplicação em amostras de águas de rios.…”

ResumoOs polímeros de impressão molecular são materiais sintéticos dotados de sítios específicos de reconhecimento. Esses materiais são obtidos por reações de polimerização que fixam, estrategicamente, monômeros funcionais ao redor de uma molécula modelo de acordo com os grupos ligantes e com a estereoquímica de ambas as moléculas. Os MIPs têm sido amplamente empregados em procedimentos de preparo de amostras, como extração e microextração em fase sólida, extração sortiva em barra de agitação, extração com adsorvente magnético, microextração com sorvente empacotado, entre outras. Este artigo de revisão tem como objetivo apresentar o que há de mais recente no emprego de MIP para extração de compostos orgânicos, evidenciando as vantagens de cada aplicação, bem como as mais promissoras tendências que sustentam a evolução e o aperfeiçoamento de cada técnica. Palavras-chavePolímeros de impressão molecular; MIP; preparo de amostras.Molecularly imprinted polymers in sample preparation for organic compounds analysis: applications and trends AbstractMolecularly imprinted polymers are synthetic materials with molecular recognition ability. These materials are obtained by polymerization reactions that fix the functional monomers around the template molecule according with the binding groups and the stereochemistry of both molecules. The MIPs have been extensively used in several applications with emphasis for sample preparation procedures as solid phase extraction, solid phase microextraction, extraction by magnetic sorbents, microextraction by packed sorbent among others. So, the objective of this review is to present the novelty in MIP use for organic compounds extraction and point out the advantages of each application, as well as what is most promising in the evolution and improvement of each technique.

“…A number of approaches to the production of imprinted membranes, including in situ polymerization (Lai et al, 1998;Sergeyeva et al, 2003;Salam and Ulbricht, 2006), polymer solution casting (Ebarvia and Sevilla Iii, 2005), phase inversion (Kobayashi et al, 2001;Trotta et al, 2005), plasma deposition (Shi et al, 1999), self-assembly of monolayers (Mirsky, 2002) and grafting (Sergeyeva et al, 2001;Panasyuk-Delaney et al, 2002) have been reported. In general the desired thickness of a polymer membrane governs the preparation method and MIP membranes have been prepared in the mm , >100 nm (Bossi et al, 2001) and <100 nm (Mirsky et al, 1997) ranges.…”

The aim of this work was to produce a thin, flexible and diffusion able molecularly imprinted polymeric matrix with good template accessibility. Membranes were prepared using a non-covalent molecular imprinting approach and their physical characteristics and binding capabilities investigated. Two materials were used, a poly(tri-ethyleneglycol dimethyacrylate-co-methyl methacrylate-co-methacrylic acid) copolymer containing 14% cross-linker and a monomer (g) to porogen (ml) ratio of 1:0.5 (A), and a blend of poly(TEGMA-co-MAA) and polyurethane (B). The polyurethane was added to improve membrane flexiblity and stability. The polymers were characterized using AFM, SEM and nitrogen adsorption, whilst binding was evaluated using batch-rebinding studies. For all membranes the specific surface area was low (<10 m(2)/g). MIP (A) films were shown to bind specifically at low concentrations but specific binding was masked by non-specific interactions at elevated concentrations. Selectivity studies confirmed specificity at low concentrations. K(D) approximations confirmed a difference in the population of binding sites within NIP and MIP films. The data also indicated that at low concentrations the ligand-occupied binding site population approached homogeneity. Scanning electron microscopy images of membrane (B) revealed a complex multi-layered system, however these membranes did not demonstrate specificity for the template. The results described here demonstrate how the fundamental parameters of a non-covalent molecularly imprinted system can be successfully modified in order to generate flexible and physically tolerant molecularly imprinted thin films.
