Silane As Matrix Material For Imprinted Polymers

General adoption

A molecularly imprinted polymer based on silicon was prepared under mild conditions.

Dai et al. Using UO2 (NO3) 2. 6H2O as molecularly imprinted molecule and tetramethoxy silicon as raw material for preparing polymers, imprinted polymer silica gel was prepared under the catalysis of nitric acid, and its adsorption capacity and selectivity were also studied.

Compared with the non imprinted polymers with the same surface area, the imprinted polymer silica gel has affinity and selectivity to UO2+2.

Subsequently, they studied the steady-state fluorescence and fluorescence lifetime of the imprinted polymer silica gel, and further proved that the prepared imprinted polymer silica gel had good selectivity and high adsorption capacity for the imprinted molecule.

Collinson and other dopamine as molecularly imprinted molecules, phenyl trimethoxy silicon and methyl trimethoxy silicon as functional monomer, tetramethoxy silicon as a crosslinking agent, catalyzed hydrolysis under acidic conditions, and then applied to the surface of the electrode to form imprinted polymer film.

The characteristics of the imprinted polymer membrane were characterized by cyclic voltammetry. The results showed that the imprinted polymer membrane had a specific adsorption capacity for dopamine and could eliminate the interference of ascorbic acid on dopamine determination.

Pinel and other [24] prepared by using acid and alkali catalyzed hydrolysis and condensation of four ethoxy silicon, prepared the imprinted silica solid, compared with the blank sample, it has strong adsorption capacity for the imprinted molecule methanol.

When silica gel was synthesized from ortho cresol as imprinted molecule, the adsorption of ortho cresol and P cresol had similar results.

He and other ionic liquids, which are insoluble with water, are used as solvents and pore forming agents to prepare imprinting.

It can selectively identify androgen.

Puleo et al. Prepared the whole lysozyme and 16 residue lysozyme C peptide imprinted polymer silica gel by combining the sol-gel technique with the antigenic determinant method.

Lysozyme imprinted polymer silica adsorbed lysozyme was 4 times the adsorbed non imprinted molecule ribonuclease, while the 16 residue lysozyme C polypeptide imprinted polymer showed only slight adsorption characteristics.

Ki and so on, using estrone as the imprinted molecule, covalently bonded with the functional monomer triethoxy propyl ISO cyanamide silane, then joined the crosslinking monomer four ethoxy silane to polymerize, heated the broken covalent bond, eluted and removed the imprinted molecule, and prepared the spherical estrone imprinted polymer, thus realizing the identification of estrone.

Ling et al. Concentrated four ethoxy silicon under hydrothermal conditions and added aluminum chloride to enhance the ability of binding to imprinted molecules. The molecularly imprinted polymers of catechol were prepared. Factors such as the acidity of the analyte, the coverage of the imprinted polymer on the silica gel surface and the acidity of the silicon aluminum solution were investigated. The electrochemical sensor was constructed on the surface of the crystal quartz microbalance by the catechol imprinted polymer, and the imprinted molecule was detected in situ.

Brandy et al prepared decane three nitrobenzene molecularly imprinted periodic mesoporous organosilicon, and porphyrins were used as an optical indicator for imprinting molecules.

The silicone material has the advantages of good stability, strong recognition ability, high sensitivity to porphyrin and high density of selective binding sites.

Zhang and so on passed three amino propyl triethoxy silicon and four ethoxy.

The 2,4,6 three nitrobenzene imprinted silica nanotubes were selectively prepared on the porous inner wall of alumina membrane by sol-gel.

The tube wall is ultra-thin with a thickness of about 15nm, which has good accessibility and low mass pfer resistance.
