Enzyme entrapment in polymer coated liposomes

Özden, M. Yaşar


OZDEN, MY; Hasırcı, Vasıf Nejat (1990-01-01)
In this study liposomes composed of only dicetylphosphate (DCP), or of a 7:2: 1 (mole ratio) mixture of phosphatidylcholine (PC), dicetylphosphate (DCP) and cholesterol (Chol.( were prepared. Resultant liposomes were coated with varying amounts of poly(1,4‐pyridinium diethylene salt(, P1,4 VN. The polymer was shown to be different from poly(4‐vinylpyridine(, P4VN, which is also obtained from the same monomer. The increase in the coating extent (or thickness( was shown by IR and UV through the increase in th...

Poly(2,5-di(furan-2-yl)thiazolo[5,4-d]thiazol) polymer was coated over a platinum electrode and new enzyme electrodeswere produced that are not found in the literature. The formation of polymerization was shown by cyclic voltammetry.Kinetic parameters of immobilized polyphenol oxidase enzyme were determined. Vmax and Km were obtained as 0.028 ±0.001 umol min1- electrode1- and 669.68 ± 64.73 mM respectively. The effect of reaction conditions over enzyme activitywere examined. The pH and temperature at which ...

Removal of cobalt from zinc sulfate solution by cementation prior to zinc electrowinning
Kayın, Pınar Burcu; Topkaya, Yavuz Ali; Department of Metallurgical and Materials Engineering (2003)
The aim of this study was to investigate the removal of cobalt from zinc sulfate solution by cementation with the help of conventional and new type of additives that were 4% Sn-zinc alloy powder and 10% Sn-zinc alloy powder, respectively. Synthetic leach solutions containing 150 g/l Zn and 75 mg/l Co were prepared and used in all of the experiments. The parameters researched with the conventional method were the amount of arsenic trioxide and the effect of copper sulfate on cementation of cobalt. While usin...
