A bulk polymerization method was used to easily and efficiently prepare homoveratric acid (3,4-dimethoxyphenylacetic acid)-imprinted polymers from eight basic monomers: 2-vinylpyridine, 4-vinylpyridine, 1-vinylimidazole, N-allylaniline, N-allylpiperazine, allylurea, allylthiourea, and allylamine, in the presence of homoveratric acid as a template in N,N-dimethylformamide as a porogen. The impri...

An interdigitated electrode sensor was designed and microfabricated for measuring the 11 changes in the capacitance of three phosphate selective molecularly imprinted polymer (MIP) 12 formulations, in order to provide hydroponics users with a portable nutrient sensing tool. The 13 MIPs investigated were synthesised using different combinations of the functional monomers 14 methacrylic acid (MAA...

Abstract A method was used to fabricate a fully inkjet-printed gas sensor matrix on photographic paper. An electrode comprising 36 interdigital electrodes in high-density layout that is easy integrate has been fabricated using combination of insulating ink and commercial silver ink. Molecular-imprinted polymer (MIP) inks were then made simple solution mixing method, these printed together with ...

Procalcitonin (PCT) is a promising biomarker for identification of the origin and severity of sepsis, which is a deadly body infection. In this work, we report the preparation of a surface plasmon resonance (SPR) biosensor which utilizes a molecular imprinted polymer surface for rapid and reliable detection of PCT. The molecular imprinted surface was prepared using a microcontact imprinting tec...

In this study, a novel method is described for the determination of tramadol in biological fluids using molecularly imprinted solid-phase extraction (MISPE) as the sample clean-up technique combined with high-performance liquid chromatography (HPLC). The water-compatible molecularly imprinted polymers (MIPs) were prepared using methacrylic acid as functional monomer, ethylene glycol dimethacryl...

Molecularly imprinted polymers (MIPs) have been playing an increasingly important role in volatile organic compounds (VOC) sensing for air quality control. The unique feature of these materials is their biomimetic molecular recognition functionality. Theoretical chemistry can advance our ability to design and synthesize new MIPs with specific functions, providing valuable insight into the syste...

The aim of the work is to design and synthesize and evaluate the polymer recognition characteristics of molecularly imprinted polymers selective for trans-retinol (R-MIP). The optimal amount of template and methacrylic acid (MAA) functional monomer as well as ethylene glycol dimethacrylate (EDMA) acts as the crosslinker was examined toward imprinting process using radical polymerization in chlo...

4-chloro-2-methylphenoxy acetic acid (mcpa) is one of the most important pesticides which is extensively used to control weeds in arable farmland. exposure to this compound occurs in general population and persons who occupationally handle it. the aim of this present work was the preparation of mcpa imprinting polymer and its application as a selective sample preparation technique for trace det...

Hydrogel-based molecularly imprinted polymers (HydroMIPs) were prepared for several proteins (haemoglobin, myoglobin and catalase) using a family of acrylamide-based monomers. Protein affinity towards the HydroMIPs was investigated under equilibrium conditions and over a range of concentrations using specific binding with Hill slope saturation profiles. We report HydroMIP binding affinities, in...
