Electrodeposition was used for the codeposition of glucose oxidase enzyme and a gold nanoparticle-silicate network onto an indium tin oxide (ITO) glass electrode. This co-entrapment of glucose oxidase enzyme in a gold nanoparticle-silicate network imparts biocatalytic activity to the film. The gold nanoparticles in the network catalyse the oxidation and(More)
Anodic deposition of thin films (up to 0.5 μm thick) of gold nanodispersion from aminosilicate stabilized gold sols is demonstrated for indium-tin oxide and platinum substrates. The films are conductive, semitransparent, and comprised of 4-6 nm gold particles each coated by a thin aminosilicate shell. Anodic deposition of stabilized gold nanoparticles is a(More)
7-N,N-Diethylamino-4-methylcoumarin, (cou-1), a readily available laser dye binding to bovine serum albumin (BSA), at room temperature has been studied by steady state fluorescence spectroscopy. Existing methods of analysis of the binding to obtain the binding parameters are based on the change in fluorescence intensity at a particular wavelength. These(More)
Extraction of vegetation is an important step for agricultural, forest and greenery mapping. The proposed method examines the complex process of land cover vegetation pattern classification using an IRS-1C LISS III image. Pre-processing was done by employing partial differential equation (PDE). Normalized differential vegetation index (NDVI) was applied to(More)
