Molecular imprinting technique offers a means of producing practical materials that are able to recognize a certain molecule in terms of shape, size and chemical functionality. In order to obtain a highly selective recognition of organophosphorus pesticides (OPPs), we synthesized molecularly imprinted polymers (MIPs) using pirimiphos-methyl as the template, methacrylic acid as the monomer and e...

Molecularly imprinted polymers bearing atrazine transforming activity were prepared by using newly designed templates that are atrazine analogues attached with an allyl or a styryl group via a disulfide bond at the 6-position, methacrylic acid as a functional monomer and styrene/divinylbenzene as crosslinkers. After polymerization, the disulfide bond was reduced to remove the atrazine moiety fr...

Surface molecularly imprinted polymers (SMIPs) for selective adsorption of ampicillin sodium were synthesized using surface molecular imprinting technique with silica gel as a support. The physical and morphological characteristics of the polymers were investigated by scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), elemental...

Fluorescent molecularly imprinted polymers have shown great promise in biological or chemical separations and detection, due to their high stability, selectivity and sensitivity. In this work, fluorescent molecularly imprinted microsphere was synthesized via precipitation polymerization, which could separate efficiently and rapidly detect τ-fluvalinate (a toxic insecticide) in water samples, wa...

Over the past few decades, molecularly imprinted polymers (MIPs) have become extremely attractive materials for biomimetic molecular recognition due to their excellent affinity and specificity, combined with robustness, easy engineering, competitive costs. MIPs are synthetic antibody mimics obtained by synthesis of 3D polymer networks around template molecules, thus generating specific binding ...

Molecular imprinting is a technique for making a selective binding site for a specific chemical. The technique involves building a polymeric scaffold of molecular complements containing the target molecule. Subsequent removal of the target leaves a cavity with a structural "memory" of the target. Molecularly imprinted polymers (MIPs) can be employed as selective adsorbents of specific molecules...

Inherently conducting polymers have been used in several applications for flexible electronics, for example in organic thin film transistors (OTFT), organic light emitting diodes (OLED), organic photovoltaic cells and electrochromic devices [1-3]. Nanoimprinting may offer a high throughput method to produce low cost devices [4] also when functional polymers such as conducting polymers are used....

Molecular imprinting is a technique used to synthesize polymers that display selective recognition for a given molecule of interest. In this study, the role of hydrogel electrostatic charge density on the recognition and selectivity properties of protein-imprinted hydrogels was explored, and the effect of variations of the template extraction protocol on the MIP recognition properties were also...

A glass slide covered with bacteria is pressed into another glass slide coated with partially cured polydimethylsiloxane (PDMS). The PDMS is hardened and the cells are removed to create a textured surface whose indentations preferentially capture the same type of bacteria when a mixture of bacteria is flowed over it. Overcoating the cell-imprinted PDMS with methylsilane groups causes the result...
