to extract active components from the traditional Chinese medicine Polygonum cuspidatum using a trans-resveratrol imprinted polymer. Good separation and purification of trans-resveratrol and emodin from the Polygonum cuspidatum extract are achieved after condition optimization. The extraction recoveries are 83% and 99% for trans-resveratol and emodin, respectively. The results show that the mol...

Simultaneously, the p-synephrine 1 template was imprinted, and a ferrocene redox probe covalently immobilized in (bis-bithiophene)-based polymer, resulting molecularly imprinted polymer (MIP) deposited on Pt electrode as thin film to form self-reporting MIP film-based chemosensor. After subsequent extraction from film, analyte determined with differential pulse voltammetry (DPV) (redox probe)-f...

We report on a new sensor strategy that integrates molecularly imprinted polymers (MIPs) with surface enhanced Raman scattering (SERS). The sensor was developed to detect the explosive, 2,4,6-trinitrotoluene (TNT). Micron thick films of sol gel-derived xerogels were deposited on a SERS-active surface as the sensing layer. Xerogels were molecularly imprinted for TNT using non-covalent interactio...

Superparamagnetic nanoparticles are of great current interest for biomedical applications in both diagnostics and treatment. Magnetic nanoparticles (MNP) can be manipulated by magnetic fields, so that when functionalized, they can be used for the purification and separation of biomolecules and even whole cells. Here we report combining the separation capabilities of MNPs with the functional (bi...

The system of polyacrylamide incorporated with methacrylic acid and 2-(dimethylamino)ethyl methacrylate was studied for the possibility of imprinting of lysozyme. The results show that approximately 27% (w/w) of the lysozyme template was not able to be extracted from the molecularly imprinted acrylamide polymers. The amount of the lysozyme template able to be extracted was increased by the addi...

In this study, a new molecularly imprinted polymer with nanoporous material of zirconium metal-organic frameworks (Zr-MOF/MIP) for diclofenac (DFC) measurement is presented. The Zr-MOF/MIP was prepared by electropolymerization method, the Zr-MOFs were used to increase electrode surface and the DFC and para- aminobenzoic acid (pABA) were used as template and functional monomer, respectively. Zr-...

Nowadays, it is still difficult for molecularly imprinted polymers (MIPs) to achieve homogeneous recognition since they cannot be easily dissolved in organic or aqueous phase. To address this issue, soluble molecularly imprinted nanorods have been synthesized by using soluble polyaniline doped with a functionalized organic protonic acid as the polymer matrix. By employing 1-naphthoic acid as a ...

Molecularly imprinted polymers were prepared and tested in different ways. 1-Methyl-2-piperidinoethylester of 4-decyloxyphenylcarbamic acid was used as the template for imprints formation. Acrylamide, 4-vinylpyridine, and methacrylic acid as monomers and methanol and acetonitrile as a porogene were used. Non-imprinted polymers were prepared for each imprinted polymer by the same procedure. Poly...

A new molecularly imprinted polymer for extraction of crocin from saffron stigmas was prepared using gentiobiose (a glycoside moiety in crocin structure) as a template. Crocin binding to gentiobiose imprinted polymer (Gent-MIP) was studied in comparison with a blank nonimprinted polymer in aqueous media. Affinity of the Gent-MIP for the crocin was more than the nonimprinted polymer at all conce...
