We propose a simple UV based soft-lithography process for fabrication of low-loss polymer PSQ-L waveguides. The fabrication process consists of two steps: the imprint step for structuring is done first on the cladding PSQ-LL layer and is followed by a spin-coating step to fill the imprinted features with core PSQ-LH layer material. Even with non-polishing waveguide facets, the extracted scatter...

In this work, the template, monomer, and cross-linker with the ratio of 1:8:40 were used to synthesize Molecularly Imprinted Polymers (MIPs) for extraction of the bioactive chemical compounds from some traditional herbs as a sorbent material. Quercetin, Methacrylic Acid (MAA), Trimethylolpropanetrimethacrylate (TRIM) and Tetrahydrofuran (THF) were used as a template, funct...

Surface Molecularly Imprinted Polymer (SMIP) for selective adsorption of di(2-ethylhexyl) phthalate(DEHP) was prepared on the surface of silica gel which was modified by aminopropyltriethoxysilane and acryloyl chloride in a two-step method. The prepared SMIP was used to prepare Molecularly Imprinted Solid-Phase Extraction (MISPE) column for selective extraction of DEHP from aqueous solution...

In this paper, we demonstrate a double nanoimprinting process that allows the formation of nanostructured polymer heterojunctions of composition and morphology that can be selected independently. We fabricated photovoltaic (PV) devices with extremely high densities (10(14)/mm(2)) of interpenetrating nanoscale columnar features in the active polymer blend layer. The smallest feature sizes are as...

A linear copolymer was prepared from 4-vinylpyridine and styrene. An ion-imprinted polymer (IIP) specific for Cr (VI) adsorption was prepared by copolymerisation of the quaternised linear copolymer (quaternised with 1,4-chlorobutane), 2-vinylpyridine functional monomer and ethylene glycol dimethacrylate (EGDMA), as the cross-linking monomer, in the presence of 1,1’-azobis(cyclohexanecarbonitril...

We explain the development of an ultra-sensitive molecularly imprinted polymer-based electrochemical sensor for rapid and selective determination bisphenol A (BPA) in human serum water samples. Electropolymerization functional monomer aniline was performed presence BPA by cyclic voltammetry (CV) to prepare a poly(aniline) based GCE (MIP(ANI)/GCE). The developed MIP surface characterized using F...

Effective non-covalent molecular imprinting on a polymer depends the extent of non-bonded interactions between template and other molecules before polymerization. Here, we first determine functional monomers that can yield doxycycline-imprinted hydrogel based hydrogen bond at prepolymerization step, revealed by dynamics (MD) simulations, docking, simulated annealing methods. Then, acrylic acid ...

Abstract Diazepam (DZP) is a benzodiazepine drug used as an anti-drug and sedative. It often misused to induce or create euphoria in combination with other drugs (high fly sensation) administered alone. So far, screening for DZP abuse sensitive analytical methods needed, its small concentrations make it difficult detect. Increased sensitivity of the method can be obtained by using preparation t...
