Biju, Vasudevanpillai published the artcileIntermittent Single-Molecule Interfacial Electron Transfer Dynamics, Synthetic Route of 10510-54-0, the publication is Journal of the American Chemical Society (2004), 126(30), 9374-9381, database is CAplus and MEDLINE.

The authors report on single-mol. studies of photosensitized interfacial electron transfer (ET) processes in Coumarin 343 (C343)-TiO₂ nanoparticles (NP) and Cresyl Violet (CV⁺)-TiO₂ NP systems, using time-correlated single-photon counting coupled with scanning confocal fluorescence microscopy. Fluorescence intensity trajectories of individual dye mols. adsorbed on a semiconductor NP surface showed fluorescence fluctuations and blinking, with time constants distributed from milliseconds to seconds. The fluorescence fluctuation dynamics were found to be inhomogeneous from mol. to mol. and from time to time, showing significant static and dynamic disorders in the interfacial ET reaction dynamics. The authors attribute fluorescence fluctuations to the interfacial ET reaction rate fluctuations, associating redox reactivity intermittency with the fluctuations of mol.-TiO₂ electronic and Franck-Condon coupling. Intermittent interfacial ET dynamics of individual mols. could be characteristic of a surface chem. reaction strongly involved with and regulated by mol.-surface interactions. The intermittent interfacial reaction dynamics that likely occur among single mols. in other interfacial and surface chem. processes can typically be observed by single-mol. studies but not by conventional ensemble-averaged experiments

Nithipatikom, Kasem published the artcileCharacterization and application of Raman labels for confocal Raman microspectroscopic detection of cellular proteins in single cells, COA of Formula: C18H15N3O3, the publication is Analytical Biochemistry (2003), 322(2), 198-207, database is CAplus and MEDLINE.

A method using confocal Raman microspectroscopy for the detection of cellular proteins in single intact cells was developed. Two approaches were used to improve the detection of these cellular components. First, compounds with high Raman scattering were investigated for potential use as Raman labels. Raman labels were conjugated to either biomols. or biotin and used as markers in the detection of cellular enzymes and receptors. Second, silver colloids were used to increase the surface-enhanced Raman scatter (SERS) of these Raman labels. Cresyl violet and dimethylaminoazobenzene are Raman labels that provide very sensitive SERS detection by a confocal Raman microscope with a HeNe laser at wavelength of 632.8 nm. The detection of 12-lipoxygenase and cyclooxygenase-1 in single bovine coronary artery endothelial cells and the binding of angiotensin II to its receptors in zona glomerulosa cells was demonstrated.

Online sample concentration by sweeping was studied in microchip micellar electrokinetic chromatog. (MEKC), By changing the distance between the injection cross and the detection points, the profile of the concentration process and the diffusion process in sweeping was elucidated. Rhodamine B injected for 4 s was best concentrated by sweeping at 9.4 mm from the injection cross and the enhancement factor was 450. At the longer distance from this point the peak of Rhodamine B was broadened and diluted by diffusion. The diffusion constant of Rhodamine B calculated from the experiment was 5.7 ¡Á 10^-6 cm² s^-1. The mixture of rhodamine B, sulforhodamine B, and cresyl fast violet was concentrated by sweeping and separated by MEKC at the same time.

Alvarez-Buylla, Arturo published the artcileCresyl violet: a red fluorescent Nissl stain, Formula: C18H15N3O3, the publication is Journal of Neuroscience Methods (1990), 33(2-3), 129-33, database is CAplus and MEDLINE.

A method is described for using cresyl violet as a red fluorescent Nissl stain. Unlike the bright-filed staining technique, fluorescent cresyl is compatible with other fluorescent dyes and tracers, such as fluorescein, Fluoro-Gold and Fast Blue. The procedure requires only minor modifications of routine bright-filed cresyl staining, the most significant being dilution of the stain. Thus, fluorescent red cresyl violet is simple to implement and may be of general use in fluorescence microscopy.

Fu, Hongxia published the artcileRatiometric Fluorescence Azide-Alkyne Cycloaddition for Live Mammalian Cell Imaging, Recommanded Product: 5,9-Diaminobenzo[a]phenoxazin-7-ium acetate, the publication is Analytical Chemistry (Washington, DC, United States) (2015), 87(22), 11332-11336, database is CAplus and MEDLINE.

Click chem. with metabolic labeling has been widely used for selectively imaging biomacromols. in cells. The first example of azide-alkyne cycloaddition for ratiometric fluorescent imaging of live cells is reported. The precursor of the azido fluorophore (cresyl violet) has a fluorescence emission peak at 620 nm. The electron-rich nitrogen of the azido group blue-shifts the emission peak to 566 nm. When the click reaction occurs, an emission peak appears at 620 nm due to the lower electronic d. of the newly formed triazole ring, which allows the authors to ratiometrically record fluorescence signals. This emission shift was applied to ratiometric imaging of propargylcholine- and dibenzocyclooctyne-labeled human breast cancer cells MCF-7 under laser confocal microscopy. Two typical triazole compounds were isolated for photophys. parameter measurements. The emission spectra presented a fluorescence emission peak around 620 nm for both click products. The results further confirmed the emission wavelength change was the result of azide-alkyne cycloaddition reaction. Since nearly all biomols. can be metabolically labeled by reported alkyne-functionalized derivatives of native metabolites, the authors’ method can be readily applied to image these biomacromols.

Cupane, A. published the artcileTwo-dimensional electronic spectroscopy signatures of the glass transition, Computed Properties of 10510-54-0, the publication is Spectroscopy (Amsterdam, Netherlands) (2010), 24(3,4), 393-397, database is CAplus.

Two-dimensional electronic spectroscopy is a sensitive probe of solvation dynamics. Using a pump-probe geometry with a pulse shaper [Optics Express 15 (2007), 16681-16689; Optics Express 16 (2008), 17420-17428], we present temperature dependent 2D spectra of laser dyes dissolved in glass-forming solvents. At low waiting times, the system has not yet relaxed, resulting in a spectrum that is elongated along the diagonal. At longer times, the system loses its memory of the initial excitation frequency, and the 2D spectrum rounds out. As the temperature is lowered, the time scale of this relaxation grows, and the elongation persists for longer waiting times. This can be measured in the ratio of the diagonal width to the anti-diagonal width; the behavior of this ratio is representative of the frequency-frequency correlation function [Optics Letters 31 (2006), 3354-3356]. Near the glass transition temperature, the relaxation behavior changes. Understanding this change is important for interpreting temperature-dependent dynamics of biol. systems.

The SERS efficiency for the AuAg alloy nanowires was estimated The nanowire were prepared by electrodeposition using anodic aluminum oxide hard templates. The estimated SERS efficiency for the alloy nanowires was comparable to the porous Au nanowires, and both the nanowires showed definitely higher mol. sensing activity than the dense Au nanowires. This result means that 1D AuAg alloy nanomaterials would be excellent SERS substrates.

Bjorgaard, Josiah A. published the artcileAmplified quenching of conjugated polymer nanoparticle photoluminescence for robust measurement of exciton diffusion length, Safety of 5,9-Diaminobenzo[a]phenoxazin-7-ium acetate, the publication is Journal of Applied Physics (Melville, NY, United States) (2013), 113(20), 203707/1-203707/6, database is CAplus.

A new method for measuring exciton diffusion length in nanoparticles (NPs) of conjugated materials is presented. Cationic acceptor dyes are used to quench the photoluminescence in NPs of the prototypical conjugated polymer poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV). Amplified quenching of MEH-PPV emission is observed with an initial Stern-Volmer constant >10⁵ M^-1. Stern-Volmer plots are nonlinear with 2 distinct quenching regimes, hinting saturation of NP surfaces with acceptor mols. at some point during titration experiments Using an assumption that highly efficient quenching of excitons occurs after saturation with acceptors at the NP surfaces, the amount of maximum emission quenching can be compared with a model of exciton diffusion to determine exciton diffusion length. By assuming quenching efficiency >80%, the measured 3 dimensional exciton diffusion length is 12 ¡À 1 nm. This result is in the lower region of reported values ranging from 10 to 25 nm in MEH-PPV thin films. Both the derived model and the exptl. methodol. allow robust measurement of exciton diffusion length for any luminescent conjugated material from which NPs can be prepared (c) 2013 American Institute of Physics.

Lunn, George published the artcileRemoval of biological stains from aqueous solution using a flow-through decontamination procedure, Safety of 5,9-Diaminobenzo[a]phenoxazin-7-ium acetate, the publication is Biotechnic & Histochemistry (1994), 69(1), 45-54, database is CAplus and MEDLINE.

Chromatog. columns filled with Amberlite XAD-16 were used to decontaminate, using a continuous flow-through procedure, aqueous solutions of the following biol. stains: acridine orange, alcian blue 8GX, alizarin red S, azure A, azure B, brilliant blue G, brilliant blue R, Congo red, cresyl violet acetate, crystal violet, eosin B, eosin Y, erythrosin B, ethidium bromide, Giemsa stain, Janus green B, methylene blue, neutral red, nigrosin, orcein, propidium iodide, rose Bengal, safranine O, toluidine blue O, and trypan blue. Adsorption was most efficient for stains of lower mol. weight (< 600). Adsorption of stain increased as the flow rate decreased; column diameter had little effect on adsorption. Adsorption of stain was greatest when finely ground resin was used, but if the resin particles were too small, column clogging occurred. Limited grinding of the resin gave increased adsorption while retaining good flow characteristics. Amberlite XAD-16 saturated with methylene blue was regenerated to its initial adsorption capacity by passing methanol through the column. The technique described provides an economical, rapid means of removing stains from aqueous solution

Chae, Weon-Sik published the artcileHelix-coiled gold nanowires for molecular sensing, Category: catalysis-chemistry, the publication is Journal of Nanoscience and Nanotechnology (2012), 12(4), 3501-3505, database is CAplus and MEDLINE.

Helix-coiled gold nanowires were fabricated by a templating route using unique composite templates consisting of anodic aluminum oxide (AAO) nanotubular membrane and confined mesoporous silica therein. A different degree of confinement energy induces a different degree of helix curvature of confined porous silica nanochannels in an AAO, which works as a hard template for the electrochem. deposition of gold, thereby rationally enabling a different degree of helix curvature of gold nano-replicas. From surface-enhanced Raman scattering experiments, it was first found that helix-coiled gold nanowires show more distinctly enhanced mol. sensing efficiency than those from simple smooth gold nanowires, and gold nanowires with the narrower lateral width show more enhanced mol. sensing efficiency than those of thicker width helix nanowires.
