“…11 Therefore, the materials having high recognition and selective capture to BPA are surely required in the viewpoint of environmental conservation in near future. For development of BPA adsorbents, molecular imprinting has been very useful as alternative methods, 12 though porous carbon, polymer-activated carbon hybrid particles, DNAfilms, and DNA hybrid microspheres could also be used in the removal of the endocrine disruptors. [13][14][15][16] To develop a novel type of highly selective adsorbing materials with artificial host sites of both specificity and high capacity, BPA-imprinted polyethersulfone (PES) microspheres were first prepared by liquid-liquid phase separation method in our previous studies.…”

Bisphenol A (BPA) imprinted polyethersulfone (PES) particles were prepared for the recognition of BPA by means of phase inversion method. During the preparation of the BPA-imprinted particles, acetone, ethanol and acetone/ethanol solutions were used to extract the template BPA molecules. The SEM morphology and the recognition experiments suggested that the acetone/ethanol provided an efficient way to extract the BPA from the imprinted PES particles. The binding and recognition ability for the imprinted particles disappeared under alkali condition, and they recovered as soon as possible when the solution changed from alkali condition to neutral or acid condition. With the addition of Na 1 , Mg 21 , and Cl 2 , the binding amounts for the imprinted particles and nonimprinted particles were not changed heavily, which suggested the potential application of the particles in seawater. In the BPA/BPA analogue mixed solution, the imprinted particles showed selectivity for the template molecules BPA. The FTIR results suggested that the PES and BPA interacted through hydrogen bonds.

“…[1][2][3] The principle of molecular imprinting involves: formation of a template-monomer complex; followed by its polymerization in the presence of crosslinking agents; removal of the templates from the polymeric matrix to create MIPs. MIPs have been used for various applications, including chromatography, [4][5][6] enzymatic catalysis, 7,8 solid-phase extraction, 9,10 and sensor technology. [11][12][13] In recent years, the preparation and application of molecularly imprinted membranes (MIM) have aroused increasing attentions.…”

The binding mechanism between 9-vinyladenine and pyrimidine base thymine in methanol was studied with UV-visible spectrophotometric method. Based on this study, using thymine as a template molecule, 9-vinyladenine as a novel functional monomer and diethylene glycol dimethacrylate as a new cross-linker, a specific diethylene glycol dimethacrylate-based molecularly imprinted polymeric membrane was prepared over a cellulose support. Then, the resultantly polymeric membrane morphologies were visualized with scanning electron microscopy and its permselectivity was examined using thymine, uracil, cytosine, adenine and guanine as substrates. This result showed that the imprinting polymeric membrane prepared with diethylene glycol dimethacrylate exhibited higher transport capacity for the template molecule thymine and its optimal analog uracil than other nucleic acid bases. The membrane also took on higher permselectivity than the imprinted membrane made with ethylene glycol dimethacrylate as a cross-linker. When a mixture including five nucleic acid bases thymine, uracil, cytosine, adenine and guanine passed through the diethylene glycol dimethacrylate-based thymine-imprinted polymeric membrane, recognition of the membrane for the template molecule thymine and its optimal analog uracil was demonstrated. It was predicted that the molecularly imprinted membrane prepared with diethylene glycol dimethacrylate as cross-linker might be applicable to thymine assay of absolute hydrolysates of DNA or uracil assay of absolute hydrolysates of RNA in biological samples because of its high selectivity for the template molecule thymine and its optimal analog uracil.

“…2) was investigated by measuring their retention on imprinted polymers with a mobile phase of chloroform/acetonitrile (9:1 (v/v)). Because previously reported BPA-imprinted polymers exhibited high affinities for BPA and its structural analogue compounds, [14][15][16] we employed this condition. The results are shown in Fig.…”

“…Due to such characteristics, many research groups reported BPA-imprinted polymers prepared using various templates. [11][12][13][14][15][16] We report herein a BPA binding imprinted polymer that has been prepared by immobilization of the template, 4,4′-bis(4-hydroxyphenyl)valeric acid, to a silica matrix. This yielded imprinted polymers of uniform size and shape with structurally controlled binding sites.…”
