“…We discovered that such ultrathin films are very useful as matrices of molecular imprinting, and have carried out extensive research [6][7][8]. We already observed enantioselectivity for carbobenzyloxy-L (and D)-amino acids with TiO2 gel ultrathin films [9].…”

TiO2 nanofilms that are imprinted by spin-coating with (R)and (S)-enantiomers of propranolol, 1,1'-bi-naphthol, and 2-(4-isobutylphenyl)-propionic acid were prepared on quartz plates by spin-coating. After template removal, the imprinted films showed much better binding for template enantiomers than the corresponding enantiomers. Moreover, the improved enantioselectivity was obtained by controlling film thickness.

“…This technique is a very useful approach for the fabrication of a matrix with molecular recognition sites that are formed by the addition of template molecules during the matrix formation process, and for the removal of the template molecule after the matrix formation [1][2][3][4][5]. Molecularly imprinted matrixes have been developed for over a decade in many fields, such as chromatography, catalysis, artificial antibodies, and sensing devices [6][7][8][9][10][11][12].…”

A molecularly imprinted polymer (MIP) was formed using an inorganic polymer by a sol-gel process. The monomers which were used to synthesize the inorganic polymer were tetraethoxysilane (TEOS), triethoxymethylsilane (MTES), and triethoxyphenylsilane (PTES). Caffeine was chosen as a template for the molecular imprinting, and theophylline was chosen as the analogous counterpart compound. The discriminating ability of the synthesized MIP to these twocompounds was estimated in this study. The MIP showed the highest discriminating ability when the ratio of TEOS:MTES:PTES in the synthesis of the inorganic polymer was 1:1:3, the reaction temperature was 50˚C, and the pH of the reaction system was ~6.5.

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.
