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...

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...

In this study, preconcentration conditions of trace amounts copper ions were investigated with solid-phase extraction (SPE) method by synthesizing activated carbon-based ion-imprinted sorbent (Cu(II)-IAC) a novel and selective approach. Flame atomic absorption spectrometry (FAAS) was used for the determination metal concentrations. For characterization sorbents, scanning electron microscopy, en...

A novel dual-function material was synthesized by anchoring a molecularly imprinted polymer (MIP) layer on CdTe/ZnS quantum dots (QDs) using a sol-gel with surface imprinting. The material exhibited highly selective and sensitive determination of ractopamine (RAC) through spectrofluorometry and solid-phase extraction (SPE) coupled with high performance liquid chromatography (HPLC). A series of ...

BACKGROUND 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 fo...

In this study, a selective and specific sorbent for radium extraction was developed the first time using ion-imprinted polymer technology. A novel original approach used in order to screen best synthesis conditions. After identifying monomer candidates, porogen, complexation from electrospray ionization mass spectrometry experiments, solubility tests, conductimetry five polymers (IIPs) were syn...
