Molecular imprinting technique is used for preparing molecularly imprinted polymer (MIP) membranes of desired recognition site, selectivity and porosity. The novelty of present work is to use a new approach for preparing imprinted monolith membrane, to study the effect of membrane porosity generated due to molecular imprinting on irreversible thermodynamical characteristics like membrane potent...

In this paper, a self-manufactured lead(II)-selective electrode, which was based on the use of lead(II) ion imprinted polymer particles (IIPs) to detect lead ions, was studied using differential pulse voltammetry. The synthesis and preparation of the IIPs was by precipitation polymerization with methacrylic acid (function monomer and lead-binding ligand), ethylene glycol dimethacrylate (the cro...

A cotinine sensor based on the dc resistance of a polymer composite films is presented. The composite film comprises a cotinine selective molecularly imprinted polymer and carbon nanotube particles. This polymer film is deposited over a gold interdigitated electrode array to measure its electrical resistance. The electrical resistance of the imprinted polymer changes upon its selective binding ...

Uniformly sized molecularly imprinted polymers, which can recognize bisphenol A (BPA), have been prepared by a multi-step swelling and polymerization method using BPA or a structurally related analogue of BPA [p-t-octylphenol (OP) or p-t-butylphenol (BP)] as the template molecule, 4-vinylpyridine as the functional monomer, and ethylene glycol dimethacrylate as the cross-linker. The BP-imprinted...

Molecular imprinting techniques have reached tremendous importance in the research of new artificial recognition systems. The investigation reports the preparation of Cu (II) ion selective polymer with high specificity and selectivity by molecular imprinting approach. For this 4-vinyl pyridine was chosen as the functional monomer and ethylene glycol dimethacrylate (EGDMA) as the crosslinking ag...

Core-shell structural magnetic molecularly imprinted polymers (magnetic MIPs) with combined properties of molecular recognition and controlled release were prepared and characterized. Magnetic MIPs were synthesized by the co-polymerization of methacrylic acid (MAA) and trimethylolpropane trimethacrylate (TRIM) around aspirin (ASP) at the surface of double-bond-functionalized Fe(3)O(4) nanoparti...
