The mechanical stability is an important phenomenon which governs many applications based properties of membranes. The inorganic materials of membrane may have been synthesized by qualitative the novel sol-gel or co-precipitation methods of material synthesis. The mMembranes of cobalt (CP) and nickel (NP) composites have been was designed by mixing of the polyvinyl chloride (PVC) with cobalt ph...

Biocompatible synthetic polymers are largely used in the bio-medical domain, tissue engineering and in controlled release of medicines. Polymers can be used in the achievement of cardiac and vascular devices, mammary implants, eye lenses, surgical threads, nervous conduits, adhesives, blood substitutes, etc. Our study was axed on the development of cytotoxicity tests for 3 synthetic polymers, n...

The design and properties of novel type of solid-contact ionophore-based ion-selective microelectrodes are reported. The microelectrode is based on an insulated needle-shaped metallic wire with an exposed apex. The ion-to-electron transducer is made of poly(3-octylthiophene-2,5-diyl) and placed between an ion-selective membrane and the metallic tip. The ion-selective polyvinyl chloride-based me...

A thermodynamic model of quaternary polymeric solution was developed for membrane formation. It incorporates two mixed solventsN-methyl-2-pyrrolidone (NMP) and tetrahydrofuran (THF), and two high molecular weight polymers cellulose acetate (CA) and polyvinyl chloride (PVC). Also, another polymeric solution was modeled by replacing (CA) with polyvinylpyrrolidone (PVP). The developed model depend...

A method is described for preparation of a dissolved oxygen meter (make Aqualytic, Germany) based triglyceride biosensor employing a polyvinyl chloride (PVC) membrane bound lipase, glycerol kinase (GK) and glycerol-3-phosphate oxidase The biosensor measures dissolved O2 utilized in the oxidation of triglyceride (TG) by membrane bound lipase, glycerol kinase (GK) and glycerol-3-phosphate oxidase...

Antigen from Yersinia pestis was adsorbed on cellulose acetate discs (0.5 cm of diameter) which were obtained from dialysis membrane by using a paper punch. ELISA for human plague diagnosis was carried out employing this matrix and was capable to detect amount of 1.3 microg of antigen, 3,200 times diluted positive serum using human anti-IgG conjugate diluted 1:4,000. No relevant antigen lixivia...
