    ABSTRACT: A novel electrochemical sensor based on a molecularly imprinted polymer, poly(o-phenylenediamine) (PoPD), has been developed for selective and sensitive detection of furosemide. The sensor was prepared by incorporating of furosemide as template molecules during the electropolymerization of o-phenylenediamine on a gold electrode. To develop the molecularly imprinted polymer (MIP), the template molecules were removed from the modified electrode's surface by washing it with 0.25 mol L−1 NaOH solution. The imprinted layer was characterized by cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and atomic force microscopy (AFM). The sensor′s preparation conditions including furosemide concentration, the number of CV cycles in the electropolymerization process, extraction solution of the template from the imprinted film, the incubation time and the pH level were optimized. The incubation of the MIP-modified electrode, with respect to furosemide concentration, resulted in a suppression of the K4[Fe(CN)6] oxidation process. Under the optimal experimental conditions, the response of the imprinted sensor was linear in the range of 1.0×10−7–7.0×10−6 mol L−1 of furosemide. The detection limit was obtained as 7.0×10−8 mol L−1 for furosemide by using this sensor. The sensor was successfully used to determine the furosemide amount in the tablet and in human urine samples with satisfactory results.

    ABSTRACT: A simple, inexpensive and highly sensitive voltammetric method for the determination of tectoridin was developed using a poly(l-Arginine) modified electrode. The redox character of tectoridin at proposed electrode was studied systematically and some dynamic parameters were calculated for the first time. A reasonable reaction mechanism of tectoridin on the poly(l-Arginine)/GCE was also dicussed and proposed, which could be a reference for the pharmacological action of tectoridin in clinical study. And the electroanalytical method for determination of tectoridin was established by differential pulse voltammograms (DPV). Under optimum conditions, the response peak currents were linear relationship with tectoridin concentrations in the range of 5.0×10−8–2.0×10−6 mol L−1 with a detection limit of 4.0×10−8 mol L−1. Therefore, the high sensitivity for tectoridin sensing at the proposed electrode was achieved, and the proposed method could also be used to detect tectoridin in the Chinese medicinal herb Blackberrylily with satisfactory results.

    ABSTRACT: Recently, new physiological roles of vitamin K homologues have been established in the treatment of rheumatoid arthritis, osteoporosis, hepatocellular carcinoma and leukemia. However, relatively high plasma protein binding, low plasma concentrations and occurrences of interfering lipids make accurate determination of vitamin K homologues a challenging task. Therefore, a sensitive and reliable salting-out assisted liquid/liquid extraction (SALLE) method coupled with HPLC-Fluorescence detection was designed for efficient extraction and quantification of trace levels of vitamin K homologues in human plasma. The investigated vitamin K homologues were phylloquinone (PK, vitamin K1), menaquinone-4 (MK-4) and menaquinone-7 (MK-7). The method employed a new efficient fluorescence derivatization reaction using ethanolic solution of stannous chloride in acidic solution to generate highly fluorescent naphthohydroquinone derivatives. Correlation coefficients were more than 0.998 in the concentration ranges of 0.3–100 ng mL−1 with detection limits of 0.1–0.17 ng mL−1 in human plasma. The developed HPLC-FL system was successfully applied for sensitive determination of vitamin K homologues in plasma of healthy volunteers. The developed method may provide a valuable tool in the pharmacoinformatic studies concerning the roles of vitamin K homologues.

    ABSTRACT: The aim of the work was to synthesize a molecularly imprinted material for the selective solid-phase extraction (SPE) of β-N-methylamino-L-alanine (L-2-amino-3-methylpropionic acid; BMAA) from cyanobacterial extracts. BMAA and its structural analogs that can be used as template are small, polar and hydrophilic molecules. These molecules are poorly soluble in organic solvents that are commonly used for the synthesis of acrylic-based polymers. Therefore, a sol gel approach was chosen to carry out the synthesis and the resulting sorbents were evaluated with different extraction procedures in order to determine their ability to selectively retain BMAA. The presence of imprinted cavities in the sorbent was demonstrated by comparing elution profiles obtained by using molecularly imprinted silica (MIS) and non-imprinted silica (NIS) as a control. The molecularly imprinted solid-phase extraction (MISPE) procedure was first developed in a pure medium (acetonitrile) and further optimized for the treatment of cyanobacterial samples. It was characterized by high elution recoveries (89% and 77% respectively in pure and in real media).The repeatability of the extraction procedure in pure medium, in real medium and the reproducibility of MIS synthesis all expressed as RSD values of extraction recovery of BMAA were equal to 3%, 12% and 5%, respectively. A MIS capacity of 0.34 μmol/g was measured. The matrix effects, which affected the quantification of BMAA when employing a mixed mode sorbent, were completely removed by adding a clean-up step of the mixed-mode sorbent extract on the MIS.

    ABSTRACT: The detection of nucleic acids is fundamental for studying their functions and for the development of biological studies and medical diagnostics. Herein, we report a new strategy for nucleic acid amplified detection by combining target-catalyzed dynamic assembly with host–guest interaction between β-cyclodextrin polymer (β-CDP) and pyrene. In this strategy, a metastable pyrene-labeled hairpin DNA probe (probe H1) and a metastable unlabeled hairpin DNA probe (probe H2) were elaborately designed as the assembly components, which were kinetically handicapped from cross-opening in the absence of target DNA. In this state, pyrene labled at the 5ʹ-termini of single-stranded stem of probe H1 would be easily trapped into the hydrophobic cavity of β-CDP because of weak steric hindrance, leading to significant fluorescence enhancement. Once the dynamic assembly was catalyzed by target DNA, a hybridized DNA duplex H1–H2 would be created continuously. In this state, it is difficult for pyrene to enter the cavity of β-CDP due to steric hindrance and weak-binding interaction, leading to a weak fluorescent signal. Thus, target DNA could be detected by this simple mix-and-detect amplification method without the need of expensive and perishable protein enzymes. As low as 10 pM of the target DNA was detected by this assay, which was comparable to that of some reported enzyme-dependent amplification methods. Meanwhile, the proposed method was further successfully applied to detect DNA in cell lysate samples, showing great potential for target detection from complex fluids. In addition, as a novel transformation of dynamic DNA assembly technology into enzyme-free signal-amplification analytical application, the proposed strategy has shown great potential for applications in a wide range of fields, such as aptamer-based non-nucleic acid target sensing, biomedicine and bioimaging.

    ABSTRACT: The double deposition and stripping steps were proposed to minimize interference and increase the sensitivity in anodic stripping voltammetry of As(III). Two working electrodes of drastically different surface areas were used for the measurements. Arsenic was first deposited at the gold film electrode of a large surface area. When the deposition step at this electrode finished, the electrode was moved at a short distance to the second electrode consisting of four gold microelectrodes. The arsenic stripped from the first electrode was partially deposited at the microelectrodes and the analytical signal was obtained by its oxidation. Due to double deposition of arsenic the interference of Cu(II) was minimized and the detection limit of As(III) was lowered by one order of magnitude. The calibration graph was linear from 5×10−10 to 1×10−8 mol L−1 following deposition time of 300 s at the first and the second electrode.

    ABSTRACT: This report describes the development of an analytical methodology on microchip electrophoresis (ME) devices coupled with capacitively coupled contactless conductivity detection (C4D) to monitor inorganic anions in environmental samples. The buffer composition as well as detection operating parameters were optimized to achieve the best separation selectivity and detector sensitivity, respectively. Electrophoretic separations of Cl-, NO3-, SO42- and NO2- were successfully performed within 60 s using a running buffer composed of 30 mmol L−1 latic acid and 15 mmol L−1l-histidine (His). The best detectability levels were found applying a sinusoidal wave with 1100-kHz-frequency and 60-Vpp amplitude. Quantitative analyzes of inorganic anions were carried out in the presence of Cr2O72- ion as internal standard (IS), which ensured great repeatability in terms of migration times (<1%) and peak areas (6.2—7.6%) for thirty consecutive injections. The analytical performance revealed a linear behavior for concentration ranges between 0—120 μmol l−1 (Cl-, NO2- and NO3-) and 0—60 μmol L−1 (SO42-) and limits of detection (LODs) varying from 2.0 to 4.9 μmol L−1. The concentration levels of anionic species were determined in aquarium, river and biofertilizer samples with recovery values between 91 and 105%. The nitrification steps associated with conversion of ammonium to nitrite followed by the conversion of nitrite to nitrate were successfully monitored in a simulated environment without fishes during a period of twelve weeks. Lastly, the monitoring of anionic species was carried out during eight weeks in an aquarium environment containing ten fishes from Danio rerio (Ciprynidae). The recorded data revealed the absence of nitrite and a gradual increase on the ammonium and nitrate concentration levels during eight weeks, thus suggesting the direct conversion of ammonium to nitrate. Based on the data herein reported, the proposed analytical methodology can be used for routine environmental analysis.

    ABSTRACT: The new type of stationary bonded phases for liquid chromatography with immobilized artificial membrane properties was synthesized. Based on the modification of diol-bonded silica gel the phosphodiester stationary phases were obtained. The structures of synthesized material were confirmed by different physico-chemical techniques such as elemental analysis, infrared spectroscopy (FTIR), (13)C CP/MAS NMR and in reversed phase and hydrophilic interaction liquid chromatography, where hydrophobic and polar compounds were sufficiently separated. To present the influence of phosphate group on the retention properties, obtained material were compared with Diol-Ester C12 stationary phase. Copyright © 2015 Elsevier B.V. All rights reserved.

    ABSTRACT: Four chiral drugs were enantioseparated by native beta-cyclodextrin (β-CD) and negatively charged carboxymethyl-beta-cyclodextrin (CM-β-CD) using capillary electrophoresis coupled with electrochemiluminescence detection (CE-ECL). Using 50mM pH 5.5 Tris-H3PO4 with 10mM CM-β-CD as a running buffer, high resolution efficiency could be obtained. With the help of isothermal titration calorimetry (ITC), nuclear magnetic resonance (NMR) and molecular modeling, the chiral recognition mechanism was comprehensively investigated. Thermodynamic parameters data from ITC revealed that CM-β-CD exhibited stronger binding affinity with analytes than β-CD, and that the driving forces of CM-β-CD responsible for chiral recognition were mainly electrostatic interactions between negatively charged CM-β-CD and positively charged analytes. In addition, from both a macroscopic and microscopic point of view, the results of NMR and molecular modeling investigation adequately confirm the conclusion by comparing the stereochemical structures of complexes. Combination of ITC, NMR and molecular modeling techniques not only can assist CE to investigate the chiral discrimination mechanism, but also can predict and guide CE enantioseparation efficiency conversely.
