    ABSTRACT: This paper mainly investigated the interaction between varenicline tartrate and bovine serum albumin. The Stern-Volmer quenching constant and bimolecular quenching rate constant were determined, furthermore, the fluorescence quenching mechanism between varenicline tartrate and bovine serum albumin was clarified. The binding constants and the number of binding sites were deduced from the double logarithm regression curve. Thermodynamic parameters were calculated, which indicated that the binding process was spontaneous and the acting force were mainly hydrophobic forces. The binding distance was calculated to be 4.80 nm, which means that there was non-radiative energy transfer from varenicline tartrate to bovine serum albumin during the process. And the bovine serum albumin conformation affected by varenicline tartrate was analyzed through ultraviolet–visible and synchronous fluorescence spectroscopy.

    ABSTRACT: The natural dyes lawsone and plumbagin (1,4-naphthoquinones) were studied by using fluorescence, Raman, infrared, surface enhanced Raman scattering and surface enhanced infrared absorption. From the absorption spectrum it was possible to infer that the enol-lawsone tautomer concentration decreases in silver colloidal solution. Plumbagin dimers, both in water and in silver colloidal solution, were identified from the fluorescence band profile and surface enhanced Raman scattering spectrum. The surface enhanced Raman scattering spectrum of lawsone was obtained by using silver colloidal solution after 12 hours settle; the keto and enol lawsone silver colloid interaction occurs. The assignment of Raman and infrared bands of both dyes was calculated with Density Functional Theory calculations. Only a monomeric structure of lawsone interacting with a silver cluster model was predicted. The monomer adopts a nearly coplanar orientation onto the silver surface; the shortest distance is 3.2 Å suggesting an electrostatic interaction.

    ABSTRACT: The conformational stability of 2-Nitrosol-1-napthol was elucidated using potential energy surface scan studies. In order to carry out a detailed vibrational spectroscopic analysis of 2-Nitrosol-1-napthol, Fourier Transform Infrared and Fourier Transform Raman spectra have been recorded in condensed phase. To determine the optimized geometry and vibrational wavenumber, Density functional theory calculations in the B3LYP/6-31G** level have been carried out followed by scaling using the scaled quantum mechanical methodology. A root mean square deviation of 9.69 cm−1 has resulted from the Scaled Quantum Mechanical treatment. Substitution of nitroso group into the 1-napthol has produced remarkable changes in the structural parameters. The ultraviolet visible spectra of the title compound dissolved in various solvents were recorded in the range of 300-500 nm. The natural bond orbital analysis, frontier molecular orbital analysis and thermodynamic features were also performed using B3LYP/6-31G** method.

    ABSTRACT: The europium/terbium ions doped gadolinium orthophosphate nanorods and microcrystals phosphors were synthesized by the hydrothermal reaction and solid-phase reaction, respectively. The structures, morphologies, and luminescent behaviors were compared. The microcrystals can obtain higher quantum efficiency compared with nanorods because of the different structures (monoclinic and hexagonal). In the ultraviolet-visible region, the gadolinium ions absorbed energy then transferred to europium and terbium ions. The energy transfer from terbium to europium existed both in microcrystals and nanorods, and it was confirmed that the energy transfer efficiency from terbium to europium in nanorods is higher than that in microcrystals.

    ABSTRACT: The mechanisms involved in signal enhancement and persistence of the plasma in double-pulse laser-induced breakdown spectroscopy are investigated, and their implications to improving figures of merit for bulk and trace analytes in sample are discussed. For double-pulse laser-induced breakdown spectroscopy, 1064 nm Neodymium YAG laser is used for ablation and 10.6 µm transversely excited atmospheric carbon dioxide laser in near collinear geometry is used for reheating. Significant improvement in signal detection and sensitivity of both bulk and trace analytes using double-pulse laser-induced breakdown spectroscopy as compared to conventional single-pulse laser-induced breakdown spectroscopy are observed. Using double-pulse laser-induced breakdown spectroscopy in near-collinear geometry, Cu and Fe as bulk and trace analytes respectively, in brass sample, showed 5 and 6 times improvement in persistence of the spectral emission. Temporal and time integrated studies show that ionic lines are significantly enhanced compared to neutral lines. Plasma characterization employing spectroscopic methods showed significant enhancement in plasma temperature resulting in higher signal as well as increased plasma persistence of the species studied.

    ABSTRACT: Graphene quantum dots were synthesized by control carbonization of citric acid and utilized for selective determination of dopamine in the presence of ascorbic and uric acids. The prepared graphene quantum dots were characterized by x-ray diffraction, transmission electron microscopy, and Fourier transform infrared, UV-Visible and fluorescence spectroscopy. The results revealed that dopamine could quench the fluorescence of graphene quantum dots through a dynamic quenching mechanism. Under the optimized conditions, the linear concentration range was obtained within 0.01–50.0 µM, with the correlation coefficient of 0.9983 and a limit of detection of 8.2 nM. This method doesn't show any interference with respect to coexisting foreign substances, even at the presence of 500 fold of ascorbic acid and uric acid.

    ABSTRACT: To recognize different vegetation species exactly, especially the species of the same family, laser-induced fluorescence characteristics of vegetation, which is excited by 556 nm laser rather than the traditional 355 nm excitation light source, is proposed to be utilized in this paper. The experimental results demonstrated that fluorescence characteristics of vegetation induced by a 556 nm laser are more obvious than that induced by a 355 nm laser. These fluorescence spectra, combined with multivariate analysis, are utilized to identify different vegetation species. The 100% of recognition rate was then acquired. Therefore, this study shows that different plant types could be accurately identified when a 556 nm laser serves as excitation light source.

    ABSTRACT: Green methods are powerful tools to minimize the use of toxic chemicals which are harmful to human beings as well as environment. The present study focuses on the use of aqueous extract of Callistemon viminalis(bottlebrush) leaves for the synthesis of silver nanoparticles. The extract was used as a bioreductant and the polyphenols and flavanoids present in extract are responsible for the reduction of Ag+ ions to zero valent silver nanoparticles. The effect of concentration of Ag+ ions and cetyltrimethylammonium bromide on the nanoparticles was examined. On increasing the concentration of stabilizer, different morphological nano-couples are formed. The successful formation of silver nanoparticles was demonstrated by using Ultraviolet-visible, Transmission Electron Microscope and Scanning Electron Microscope. Transmission electron microscope image analysis showed wide size distribution having dimer nanoparticles of hexagonal-triangular, square-triangular, spherical-triangular, spherical-spherical square-spherical morphologies. The antibacterial activity of extract reduced silver nanoparticles against four strains viz. Escherichia coli, Staphylococcus aureus, Klebsiella pneumoniae and Salmonella typhimurium was evaluated by calculation of minimum inhibitory concentration and minimum bactericidal concentration. The results show that synthesized nanoparticles could inhibit the growth of various bacteria tested.

    ABSTRACT: The interaction between cefepime hydrochloride and lysozyme at different temperatures was investigated using fluorescence quenching and synchronous fluorescence spectroscopy. The results demonstrated that the interaction between lysozyme and cefepime hydrochloride was taking place via static quenching with 1:1 binding ratio. The binding constants obtained from above method were of the same order of magnitude and very similar. The electrostatic interaction played a key role during the binding process.In addition, the conclusions obtained from two methods were consistent. It indicated that the synchronous fluorescence spectrometry could be used to study the binding mechanism between drugs and lysozyme.

    ABSTRACT: Quantum path control on the harmonic emission from hydrogen molecular ion is investigated via combining an intense few-cycle laser and a half-cycle pulse. The results show that the quantum paths of returning electrons can be effectively modified due to the introduction of the half-cycle pulse which extremely dominates the acceleration process of ionized electron. With the favorable conditions, the long quantum path is completely eliminated and an isolated 61 as pulse can be obtained by superposing proper harmonics. Moreover, the electron wave packet distributions and the double-well model are presented to explore the underlying physical mechanism.

    ABSTRACT: The saturation problem associated with the use of normalized difference vegetation index for crop variable estimation is well known. However, its physical mechanism is not systemically explored. The wavebands computing the vegetation indices also suffered saturation when the leaf area index and above ground biomass reached to 2.5 and 1 kg m−2, respectively. We thought that the saturation might be not only referred to normalized difference vegetation index, but also to certain wavebands. Furthermore, the performances of seven different vegetation indices were assessed on overcoming the saturation. The findings will improve our understanding of the spectral saturation.

    ABSTRACT: To utilize the wasted coat resources, which are usually discarded in the process of mung bean derived food, and understand the traditional use of mung bean, nuclear magnetic resonance based metabolic fingerprinting approach was used to compare the chemical composition between the coat and kernel. The results showed that the flavonoids, isovitexin and vitexin, were only present in the coat, while the kernel contained higher levels of amino acids and sugars. In addition, the coat showed much stronger 2, 2-Diphenyl-1-picrylhydrazyl scavenging activity than the kernel, which was in accordance with the analysis result from the biplot of partial least squares.

    ABSTRACT: In this research, ferroferric oxide nanoparticles were coated with silicon dioxide and further functionalized with alizarin complexone as the adsorbent of magnetic solid phase extraction, aiming to extraction and preconcentration of heavy metals in Gastrodiae rhizoma samples. The determination of heavy metals was carried out by flame atomic absorption spectrometry. The results showed that the functionalized magnetic nanoparticles demonstrated higher extraction efficiency for copper, lead, and cadmium. The synthesized magnetic sorbents were characterized by transmission electron microscope, X-ray diffraction, and fourier transformed infrared spectra. Different parameters influencing the extraction efficiency including: amount of sorbent, sample pH, sorption time, solution volume, elution solvent and reuse times were optimized. Under the optimal conditions, the method detection limit was 0.18, 0.25 and 0.12 µg/L for copper, lead, and cadmium, respectively. The proposed method was successfully applied to extract copper, lead, and cadmium in Gastrodiae rhizoma samples and the recoveries of the samples ranged from 90.0-102.0% and relative standard deviations (RSDs, n = 5) were in the range of 1.93-3.82%.

    ABSTRACT: In this study, the molecular interaction of silybin with hyaluronidase was investigated by spectroscopic methods and molecular docking. It was found that silybin had strong ability to quench the intrinsic fluorescence of hyaluronidase by a static quenching procedure. The binding constants were obtained at three temperatures (293 K, 298 K and 310 K). The results of synchronous fluorescence and three-dimensional fluorescence and molecular docking showed that silybin bound into the hyaluronidase cavity site and the binding of silybin to hyaluronidase could induce micro-environmental and conformational changes in hyaluronidase, which resulted in the reduced hyaluronidase activity. The thermodynamic parameter analysis and molecular docking experiments revealed that all types of non-covalent interaction, including hydrogen bonding interaction, van der Waals forces, hydrophobic interaction and electrostatic interaction were present in the binding process of silybin with hyaluronidase. The results obtained here will provide direct evidence at a molecular level to understand the mechanism of inhibitory effect of silybin against hyaluronidase.

    ABSTRACT: The photoluminescence signal of zinc oxide/silver films based on digital video disk template were carried out compared with that of the planar mode. The spectra that on silicon showed a strong bandgap emission around 378 nanometer and a defect related emission band centered at ∼ 470 nanometer. After adding digital video disk template, it resulted in an increased signal of both the Ultra Violet and the visible region, but the Ultra Violet emission enhancement was notable. That the enhancement of band edge emission resulted from surface plasmon resonance coupling between silver and zinc oxide was discussed in detail.

    ABSTRACT: The interaction between gliclazide and bovine serum albumin was investigated by fluorescence and synchronous fluorescence spectroscopy. From the experimental results, it was found that the quenching mechanism was static. The results of the synchronous fluorescence obtained indicated that the binding of gliclazide with bovine serum albumin could affect conformation in bovine serum albumin. In addition, the binding constants (Ka), binding sites (n), thermodynamic parameters, binding forces, Hill's coefficient, binding rate of gliclazide to protein calculated from two methods using the same equation were consistent at three different temperatures (298, 310, 318 K). This indicated that as a useful supplement to the conventional method, synchronous fluorescence spectroscopy could be used to study the mechanism of drugs and proteins. The conclusion was verified by UV/vis method.

    ABSTRACT: The surface-enhanced Raman scattering spectroscopy were employed to analyze the biochemical composition of the saposhnikovia divaricata decoction, which is a common traditional chinese medicine. No reliable Raman peak was observed in traditional Raman spectra of saposhnikovia divaricata decoction. However, 12 main Raman peaks (534, 616, 648, 685, 730, 781, 850, 958, 1242, 1319, 1460 and 1571 cm−1) were observed in the surface-enhanced Raman scattering spectroscopy spectra from the mixture of silver colloids with saposhnikovia divaricata decoction as a result of the silver colloid enhanced effects on the Raman scattering of saposhnikovia divaricata decoction. The results demonstrated that the surface-enhanced Raman scattering spectroscopy may provide a new kind of non-destructive, accurate, direct and fast detecting method for the saposhnikovia divaricata decoction or other traditional Chinese medicine in the form of decoction.
