The present work investigates the adsorption of a cationic oxazine dye, cresyl violate acetate (CVA), into the anionic Laponite nano clay platelets through electrostatic interaction. The adsorption resulted in the formation of Clay-CVA hybrid mols. at the air water interface. CVA tagged nano clay platelets were further adsorbed onto a cationic surfactant, Octadecylamine (ODA), matrix at the air water interface and as a consequence a stable and almost uniform ODA-Clay-CVA hybrid monolayer was formed. The organization of hybrid mols. in Langmuir trough was changed under monolayer compression resulting in the formation of different sized and shaped domain structures. Surface pressure – area per mol. (¦Ð-A) isotherm studies and in-situ Brewster angle microscopic (BAM) studies were employed in this investigation to explore the monolayer chracteristics.

Churukian, Charles J. published the artcileA simple colloidal silver method (autometallographic technique) for demonstrating inorganic mercury in brain sections, Application of 5,9-Diaminobenzo[a]phenoxazin-7-ium acetate, the publication is Journal of Histotechnology (2000), 23(4), 337-339, database is CAplus.

Standard methods for mercury measurement estimate total mercury burden in tissues but are not informative about cellular localization, for which histochem. techniques are needed. Because the main target of the toxic effects of mercury is the nervous system, it is of particular interest to localize its reservoir within the brain. This paper presents a simple, autometallog. method for demonstrating inorganic mercury in paraffin sections of brain by utilizing a buffered colloidal silver solution that contains hydroquinone. Formalin fixed, paraffin processed brain sections are cut at 7 ¦Ìm and hydrated with deionized water. The sections are placed in a buffered colloidal silver nitrate solution containing hydroquinone and kept in a 37¡ã oven for 18 to 20 min. They are then washed immediately in hot running water and rinsed in deionized water. Following treatment with 2% sodium thiosulfate for 1 min, they are rinsed in deionized water and counterstained with nuclear fast red for 3 min or with cresyl violet acetate for 5 min. After the slides are rinsed in deionized water, they are dehydrated in alc., cleared in xylene, and mounted with synthetic resin. Mercury stains black and the results are consistent and reliable.

In this study, solvents polarity effects on nonlinear properties of Crysel violet acetate (CVA) dye were investigated by Z-scan method. Nonlinear parameters (absorption coefficient and refractive index) for CVA dye in solvent media were obtained using exptl. setup. The obtained exptl. results demonstrate that the mechanism of nonlinear absorption depend highly on the properties of surrounding mol. media and the character of intermol. interactions. Contributions of intermol. interactions were determined by exploiting these results with Kamlet-Taft (KAT) polarity parameters. The refractive index in different solvents shows neg. sign (coefficient’s order is 10^-7). Also, nonlinear absorptions in different solvents show pos. sign and the obtained coefficient’s order is 10^-4.

Kubota, L. T. published the artcileElectrochemical investigation of some aromatic redox mediators immobilized on titanium phosphate, Name: 5,9-Diaminobenzo[a]phenoxazin-7-ium acetate, the publication is Quimica Analitica (Barcelona) (2000), 19(Supl. 1), 15-27, database is CAplus.

Some phenazines, phenoxazines, and phenothiazines as well as riboflavin were immobilized on amorphous titanium phosphate (TP) by adsorption from aqueous solutions The immobilized organic redox compounds revealed a reasonable electron transfer rate and with a formal potential (E¡ã’) at pH 7.0 more pos. than that observed for their corresponding aqueous soluble counterparts. This shift in the E¡ã’ was partly assigned to the acidity of TP. The E¡ã’ of the immobilized redox compound remained virtually constant with a variation of the solution pH between 1 and 8 and was attributed to the protection effect of the matrix. Attenuated total reflectance IR spectroscopy (ATRIS) of methylene blue and riboflavin adsorbed onto TP deposited on ZnSe-prism was also used to shed further light on the interaction between these aromatic redox compounds and TP, as ATRIS is sensitive to the mode of adsorption of mols. on surfaces. Four of the immobilized compounds (Nile blue, methylene blue, toluidine blue O, methylene violet) were shown to be efficient as electron transfer mediators to electrocatalytically oxidize NADH in aqueous solution at pH 7.0. The kinetic parameters such as apparent Michaelis-Menten constant were obtained for these four immobilized mediators.

McCoy, Michael J. published the artcileDetection of angiotensin II binding to single adrenal zona glomerulosa cells by confocal Raman microspectroscopy, Application of 5,9-Diaminobenzo[a]phenoxazin-7-ium acetate, the publication is Proceedings of SPIE-The International Society for Optical Engineering (1999), 195-203, database is CAplus.

We developed a confocal Raman microspectroscopic technique to study ligand-receptor bindings in single cells using Raman-labeled ligands and surface-enhanced Raman scattering (SERS). The adrenal zona glomerulosa (ZG) cells were used as a model in this study. ZG cells have a high d. of angiotensin II (AII) receptors on the cellular membrane. There are two identified subtypes of AII receptors,namely AT1 and AT2 receptors. AII is a peptidic hormone, which upon binding to its receptors, stimulates the release of aldosterone from ZG cells. The cellular localization of these receptors subtypes was detected in single ZG cells by using immunocomplexation of receptors with specific antibodies and confocal Raman microspectroscopy. In the binding study, we used biotin-labeled AII to bind to its receptors in ZG cells. Then, avidin and Raman-labeled AII. The binding was measure directly on the single ZG cells. The results showed that the binding was displaced with unlabeled AII and specific AII antagonists. This is a rapid and sensitive technique for detection of cellular ligand bindings as well as antagonists screening in drug discovery.

Adsorption of a number of flavins, phenazines, phenoxazines, and phenothiazines on zirconium phosphate (ZP) was carried out in aqueous solution The adsorbed organic dyes on ZP were used to prepare modified C paste electrodes. The electrochem. properties of the immobilized dyes were investigated and also their possible use to electrocatalytically oxidize NADH. The formal potential (E⁰‘) of most of the adsorbed flavins, phenoxazines, and phenothiazines shifted markedly towards more pos. potentials compared with their values in solution The pH of the contacting solution did not affect their E⁰‘-values between pH 1-9. The phenazines did neither present good electrochem. response nor electrocatalytic activity for NADH oxidation and their E⁰‘-values remained pH dependent. In contrast, adsorbed flavins, phenoxazines, and phenothiazines presented good electron transfer rates between the electrode and the adsorbed mol. dye at pH 7.0.

The isotropic and anisotropic solvation characteristics of cresyl violet acetate (CVA) were studied in isotropic liquid solutions and in polar nematic matrixes as a function of the solvent type and concentration The interaction of the ionic dye with the anisotropic surrounding and with that of the isotropic solvents was studied and compared. Probably the nematic liquid crystalline solvents might create stronger solvation than the isotropic solvents. The spectral shifts were correlated by the solvent permittivity and Kamlet-Taft parameters. The polarized absorption spectra of cresyl violet acetate were measured at 400-800 nm and the dichroic ratio R and degree of anisotropy S of this dye in the liquid crystalline host determined

Wan, Qiong-Qiong published the artcileA Cresyl Violet-Based Fluorescent Off-On Probe for the Detection and Imaging of Hypoxia and Nitroreductase in Living Organisms, Application In Synthesis of 10510-54-0, the publication is Chemistry – An Asian Journal (2014), 9(8), 2058-2062, database is CAplus and MEDLINE.

A new cresyl violet-based fluorescent off-on probe has been developed through a one-step synthesis for the detection of nitroreductase (NTR) and hypoxia. The detection mechanism is based on the NTR-catalyzed reduction of the probe to cresyl violet, accompanied with a large fluorescence enhancement at a long wavelength of 625 nm. The probe can detect NTR in aqueous solution with high selectivity and sensitivity, and the detection limit is 1 ng mL^-1 NTR. Most importantly, the probe has been successfully used to image not only NTR and hypoxia in living cells, but also the distribution of NTR in zebrafish in vivo.

Lv, Qian published the artcileTotal Aqueous Synthesis of Au@Cu_2-xS Core-Shell Nanoparticles for In Vitro and In Vivo SERS/PA Imaging-Guided Photothermal Cancer Therapy, Name: 5,9-Diaminobenzo[a]phenoxazin-7-ium acetate, the publication is Advanced Healthcare Materials (2019), 8(2), n/a, database is CAplus and MEDLINE.

Both accurate tumor navigation and nanostructures with high photothermal (PT) conversion efficiency are important but remain challenging to achieve in current biomedical applications. This study reports an anion exchange-based facile and green approach for synthesizing Au@Cu_2-xS core-shell nanoparticles (NPs) in an aqueous system. In addition to the PT effect of the suggested NPs, the surface-enhanced Raman scattering (SERS) is also significantly improved due to the tailored localized surface plasmon resonance coupling between the Au metal core and the Cu_2-xS semiconductor shell. Using an epitaxial strategy, Au@Cu₂O NPs are first obtained by the in situ reduction of cupric hydroxide on a cresyl violet acetate-coated Au core; then, Au@Cu_2-xS NPs are obtained via anion exchange between the S^2- and Cu₂O shell. Both the Cu/S at. ratio and the Cu_2-xS shell thickness can be adjusted conveniently. Hence, the ideal integration of the plasmonic Au core and Cu_2-xS shell into a single unit is conducive not only to highly efficient PT conversion but also to the construction of a SERS-based navigator. This new type of SERS-guided NP, with enhanced photoacoustic signals, is an important candidate for both accurate tumor navigation and nondestructive PT treatment guided in vivo by two modes of optical imaging.
