Spectroscopic and molecular dynamics (MD) studies of organic dye molecules in polar solvents are performed to investigate the nature of solute-solvent interactions. Experimental and MD data demonstrate that positively charged molecules rotate more slowly than neutral and negatively charged solutes in polar aprotic solvents. MD simulations of the resorufin, resorufamine, and thionine molecules i...

In this work, a novel amperometric immunosensor based on multi-walled carbon nanotubes-thionine-chitosan (MWCNTs-THI-CHIT) nanocomposite film as electrode modified material was developed for the detection of chlorpyrifos residues. The nanocomposite film was dropped onto a glassy carbon electrode (GCE), and then the anti-chlorpyrifos monoclonal antibody was covalently immobilized onto the surfac...

Poly(brilliant green) (PBG) and poly(thionine) (PTH) films have been formed on carbon film electrodes (CFEs) modified with carbon nanotubes (CNT) by electropolymerisation using potential cycling. Voltammetric and electrochemical impedance characterisation were performed. Glucose oxidase and uricase, as model enzymes, were immobilised on top of PBG/CNT/CFE and PTH/CNT/CFE for glucose and uric ac...

I n 1955, Jackson described the existence of circulating cytoplasmic granules of polysaccharide-protein composition in the fibrogenic cells of bone, tendon, and cornea of the fowl embryo which were growing in tissue culture. Long-lasting metachromasia developed in these granules when toluidine blue or thionine was added to the culture medium. It was not specifically stated in that paper that th...

Methods. Cryostat sections of human retina were overlaid with blood lymphocytes from healthy subjects, and experimental conditions were sought by which preferential attachment of the cells occurred to blood vessel walls in the retinal sections. Adherent lymphocytes were identified by staining with methyl green-thionine, and transected blood vessels were identified by their structure and by stai...

Methylene Blue (MB) is one kind of textile dye from thiazine dyes that negatively impacts humans and the environment. Therefore, it very important to determine an effective method decolorize it. Brown-rot fungus Gloeophyllum trabeum can MB, but its ability was still relatively low required a long incubation time. In this study, effect adding bacterium Pseudomonas aeruginosa at 2, 4, 6, 8, 10 mL...
