This article presents a work aiming at thermodynamically and kinetically interpreting the specific sorption and recognition by a molecularly imprinted polymer. Using Boc-L-Phe-OH as a template, the imprinted material was prepared. The result indicates that the prepared polymer can well discriminate the imprint species from its analogue (Boc-D-Phe-OH), so as to adsorb more for the former but les...

Molecularly imprinted polymer (MIP) microspheres for Piperine were synthesized by precipitation polymerization with a noncovalent approach. In this research Piperine was used as a template, acrylic acid as a functional monomer, ethylene glycol dimethacrylate as a cross-linker, and 2,2'-azobisisobutyronitrile (AIBN) as an initiator and acetonitrile as a solvent. The imprinted and nonimprinted po...

Background & Aims: Magnetically molecularly imprinted polymers (MMIPs) are assumed as kind of sorbent polymers ‎which can separate or determine bioactive compounds from environment fast and specifically.  ‎Magnetic properties, stability at various conditions (temperature , ionic strength and pH) and selective ‎function are among the advantages of these polymers in determin...

Molecular imprinting has proved to be an effective technique for generating specific recognition sites in synthetic nanopolymers. These sites are tailor-made in situ by copolymerization of functional monomers and cross-linked around the template molecules. The print molecules are subsequently extracted from the polymer, leaving accessible complementary binding sites in the polymer network. Desp...

− The molecular imprinting technique is a reliable technique for the preparation of materials of predetermined selectivity. It is highly significant in research of the structure of enzyme, mechanism of receptor-antibody and analytical chemistry. In analytical separation science, molecularly imprinted polymers have been applied in several analytical techniques, such as liquid chromatography, cap...

Molecularly imprinted polymers (MIP) exhibiting high selectivity and affinity to the predetermined molecule (template) are now seeing a fast growing research. However, optimization of the imprinted products is difficult due to the fact that there are many variables to consider, some or all of which can potentially impact upon the chemical, morphological and molecular recognition properties of t...

A molecular imprinted polymer (MIP) was computationally designed and synthesized for the selective extraction of metaproterenol (MTP), from human plasma. In this regards semi empirical MP3 and mechanical quantum (DFT) calculations were used to find a suitable functional monomers. On the basis of computational and experimental results, acrylic acid (AA) and DMSO:MeOH (90:10 %V/V) were found to b...

Molecular imprinting is a well-known fabrication technique for designing artificial receptors and molecular sensors. The technique resembles a lock and key mechanism and utilizes shape-complementary cavities within polymeric materials as molecular recognition sites for various relevant molecules. In this study, we prepared molecularly imprinted polypeptide gel layers based on cyclodextrin-modif...

In this study, molecularly imprinted polymers were synthesized for dibutyl phthalate as a bioactive chemical compound with antifungal activity which produced by Trichoderma Harzianum (JX1738521). The molecularly imprinted polymers were synthesized via precipitation polymerization method from methacrylic acid, dibutyl phthalate and trimetylolpropantrimethacrylate as a functional monomer, templat...
