Alkoxysilane-grafted silica/polyhedral oligomeric silsesquioxane with methacryl substituents (SiO2/silane/POSS) hybrid material was synthesized according to hydrolyzation and condensation reactions in the so-called “bifunctionalization process.” It is a new attractive system because of its physicochemical, especially thermal and structural, properties. This innovative method of preparation as well as specific physicochemical and useful properties determine the potential applications of such products in many industries. The structure and physicochemical parameters of obtained hybrid systems were characterized using infrared spectroscopy (FTIR),13C and29Si solid-state nuclear magnetic resonance (CP MAS NMR), and thermal analysis. The mechanism of bifunctionalization reaction was proposed. The chemical immobilization of silane coupling agent and Methacryl POSS onto silica support surface was noted during the study. Those changes caused a significant increase in the hydrophobic character of fillers obtained. Moreover, changes in thermal stability of SiO2/silane/POSS hybrid systems in comparison to pure POSS modifier were also observed.

Abstract We have prepared a dry film for the enzymic determination of total serum cholesterol. It consists of a transparent support bearing a buffered gelatin layer, and a white reflective spreading layer that contains all of the necessary components for the detection of cholesterol. The method is based on (a) hydrolysis of cholesterol esters to cholesterol by cholesterol ester hydrolase (EC 3.1.1.13), (b) oxidation of cholesterol to cholest-4-en-4-one and hydrogen peroxide by cholesterol oxidase (EC 1.1.3.6), and (c) oxidation of a triarylimidazole leuco dye with hydrogen peroxide in the presence of peroxidase (EC 1.11.1.7) to produce a dye with maximum absorption at about 650 nm. For use over a wider range of concentration, the dye density is read at 540 nm. With reflection densitometry and appropriate mathematical transformation, readings and cholesterol concentrations are linearly related to 5500 mg/L. Results correlate well with those by the Abell-Kendall comparison method (slope 0.97, intercept 92.5, correlation coefficient 0.974, Sy.x = 250.7), and the method is precise (CV of 1.2-2.3% for a control fluid and patients' samples) and relatively free of interferences.
