Three rapid spectrophotometric methods were developed for the determination of sunitinib based on the formation of ion-pair complex in acidic medium with bromocresol purple, bromothymol blue, and bromophenol blue. The formed ion-pair complexes, extractable with chloroform, were measured at 422 nm for bromocresol purple, 425 nm for bromothymol blue and 427 nm for bromophenol blue. All these meth...

This paper, the second in a series concerning the use of indicator dyes to study the reactions of organic acids and bases in organic solvents, deals with halogen derivatives of phenolsulfonephthalein. Spectrophotometric data are given for mixtures of bromocresol green, bromophenol blue, iodophenol blue, and tetrabromophenol blue with primary, secondary, and tertiary aliphatic amines in benzene;...

Interaction of bromophenol blue with bovine serum albumin and its five succinylated forms was studied spectrophotometrically at three different ionic strengths, i.e. 0.04, 0.15 and 1.0 and at two different pH values, namely pH 7.0 and pH 5.0 respectively. Results showed a decrease in bromophenol blue binding on increasing succinylation at low ionic strengths. This decrease was more marked at pH...

Chromosphere such as triaryl methane family of dyes used in various industries can affect the body living organism system upon interaction with most biochemical molecule is DNA. In this research, binding mode chromophore that Bromothymol blue, Bromophenol Bromocresol green and Malachite double strand DNA phosphate buffer at pH 6.9 was investigated through UV/VIS spectroscopy. The study shows bl...

We explored the potentials of microarray printing using quill-like microcantilevers onto solid supports that are typically used in microspot printing, including paper, polymeric nitrocellulose and nylon membranes. We compared these membranes with a novel porous poly(2-hydroxyethyl methacrylate-co-ethylene dimethacrylate) support (HEMA) with narrow pore size distribution in the 150 nm range, whi...
