Abstract

Analysis of powder samples available in small quantities has been carried out using metal-assisted gas plasma by utilizing a transversely excited atmospheric (TEA) CO laser. The powder was

homogeneously mixed with Si grease, and the mixed powder was painted on a metal subtarget. When a TEA CO laser was directly focused on the metal subtarget at atmospheric pressure of He gas, a high- temperature He gas plasma was induced. It is assumed that the powder particles were vaporized to be effectively atomized and excited in the gas plasma region. This method has been employed in the rapid analyses of elements in organic and inorganic powder samples present in small quantities. Detection of trace elements of Cr and Pb has been successfully made by using the supplement powder and loam soil, respectively. The detection limits of Pb in loam soil were approximately 20 mg/kg. © 2017, Springer Science+Business Media New York.

Quantum yields and luminescence lifetimes of singlet oxygen in 18 different solvents and binary mixtures were measured using laser fl uorometry. The results allowed a direct effect of the refractive index on the radiative rate constant k

transition caused by a change of photon state density in addition to an indirect effect through a local-fi eld factor to be determined. The experimentally observed rise of k

_r

with increasing medium refractive index could not be explained by the infl uence of only these two factors. The discrepancy was overcome by taking into account changes of the singlet-oxygen transition dipole moment. Consideration of all three factors explained the infl uence of the medium on rate constant k

Keywords: singlet oxygen, spontaneous-emission rate constant, luminescence quantum yield, molecular polarizability.

Introduction. Molecular oxygen plays a decisive and essential role in nature. Despite its relative simplicity, this homonuclear diatomic molecule possesses several unique physical and chemical properties related mainly to its ground-state electronic structure and the presence of two unpaired electrons and two low-energy excited electronic singlet states. It can exist as various chemically reactive species, including O

-state, i.e., singlet oxygen (

) [1–3].

Luminescence emission of molecular

O

can be used for direct monitoring of the generation and consumption of this reactive oxygen species during numerous physical and chemical processes that occur in biosystems and during photodynamic therapy. It is noteworthy that

O

luminescence is diffi cult to detect because of its low quantum yield [1, 2].

The

The infl uence of the formation of noncovalent intermolecular complexes with bovine serum albumin (BSA) on the spectral and fl uorescent properties of the anionic oxacarbocyanine dye 3,3′-di-(γ-sulfopropyl)-5,5′-diphenyl- 9-ethyloxacarbocyanine betaine (OCC) was studied. Binding of OCC to BSA increased signifi cantly the dye fl uorescence. Changes in the absorption and fl uorescence spectra of OCC upon interaction with BSA argued in favor of a shift of the dye cis–trans equilibrium in the complex. The effects of adding albumin-denaturing compounds (urea, sodium dodecyl sulfate) on the spectral and fl uorescent properties of the dye in the OCC–BSA complex were studied. It was concluded that OCC can act as a probe for albumins and can be used to study protein denaturing.

Keywords: oxacarbocyanine dye, bovine serum albumin, noncovalent complex, spectral and fl uorescent properties, protein denaturation.

Introduction. The search for effective biomedical spectral and fl uorescent probes and sensitizers drives studies of the interactions of dyes with biomacromolecules [1, 2]. Polymethine (cyanine) dyes are especially interesting in this respect because of their unique properties. These compounds have high extinction coeffi cients (~10

in the range 400–1200 nm).

The fl exibility of their molecules is responsible for low fl uorescence-quantum and intersystem-crossing yields [3, 4].

Dynamic equilibrium between the trans- and cis-isomers was observed in solutions of several meso-substituted polymethine dyes [4–6]. The dye spectral and fl uorescent properties can vary considerably upon complexation to biopolymers. This opens possibilities for using polymethine dyes as molecular probes for detecting DNA, RNA, and serum albumins [7, 8].

Previously, we studied the effects of interaction with human serum albumin (HSA) on the spectral and fl uorescent properties of the anionic meso-substituted oxacarbocyanine dye 3,3′-di-(γ-sulfopropyl)-5,5′-diphenyl-9-ethyloxacarbocyanine betaine with a pyridinium cation (OCC) [9]. OCC was proposed as a probe for HSA. The present work focused on further studies of the noncovalent interaction of OCC with albumins (bovine serum albumin, BSA).

Experimental. The dye OCC was supplied by Prof. B. I. Shapiro (NII Khimfotoproekt). BSA was purchased (Sigma-Aldrich, USA). Distilled H

O was used as the solvent. Dye solutions were prepared immediately before taking measurements. Protein was denatured using crystalline urea (chemically pure, Khimmed, Russia) and sodium dodecyl sulfate (SDS, chemically pure, Sigma-Aldrich, USA).

Absorption spectra of the dyes were measured on an SF-2000 spectrophotometer (Russia); fl uorescence spectra, in standard 1-cm quartz cuvettes on a Flyuorat-02-Panorama spectrofl uorimeter (Russia). Fluorescence and fl uorescence excitation spectra were corrected for the spectral parameters of the excitation channel and for solution absorption.
