Immobilization of invertase and glucose oxidase in poly 2-methylbutyl-2-(3-thienyl) acetate/polypyrrole matrices
Isik, S; Alkan, S; Toppare, Levent Kamil; Cianga, I; Yagci, Y (Elsevier BV, 2003-12-01)
Immobilization of invertase and glucose oxidase in conducting polypyrrole and copolymers of poly 2-methylbutyl-2-(3-thienyl) acetate with pyrrole were achieved via electrochemical method. Sodium dodecyl sulphate was found to be the most suitable supporting electrolyte. Maximum reaction rate, Michaelis-Menten constant and optimum temperatures were determined for native and immobilized enzymes. Storage and operational stabilities of enzyme electrodes were also investigated.

Immobilization of invertase in conducting polypyrrole/PMMA-co-PMTM graft copolymers
Yildiz, HB; Kiralp, S; Toppare, Levent Kamil; Yagci, Y (Wiley, 2005-04-15)
In this study, invertase was immobilized in copolymer electrodes constructed. Three different types of polymethyl methacrylate-co-polymethyl thienyl methacrylate matrices were used to obtain copolymers that were characterized by FT-IR spectroscopy. Immobilization of enzymes was carried out by the entrapment of the enzyme in conducting polymer matrices during electrochemical polymerization of pyrrole through thiophene moieties of polymers. Immobilization of the enzyme was achieved by application of 1.0 V con...
Immobilization of glucose oxidase and urease in hydrogel matrices
Gurel, I; Arica, MY; Hasırcı, Vasıf Nejat (1997-01-01)
Immobilization of glucose oxidase and urease in hydrogels of 2-hydroxyethyl methacrylae, and N-vinyl pyrrolidone (NVP) was achieved by irradiation (using UV kand gamma-rays). The effect of radiation on entrapment efficiencies, retention of activities and swelling rates was obtained. To optimize the system, duration of exposure, reaction temperature, co-monomer concentrations, initiator and cross linker compositions were varied. The repeated reusability of the generated products was also tested. It was found...
Immobilization of invertase in conducting copolymers of 3-methylthienyl methacrylate
Çırpan, Ali; Toppare, Levent Kamil; Yagci, Y. (Elsevier BV, 2003-4)
Immobilization of invertase in conducting copolymer matrices of 3-methylthienyl methacrylate with pyrrole and thiophene was achieved by constant potential electrolysis using sodium dodecyl sulfate (SDS) as the supporting electrolyte. Polythiophene (PTh) was also used in entrapment process for comparison. Kinetic parameters, Michaelis-Menten constant, Km, and the maximum reaction rate, Vmax, were investigated. Operational stability and temperature optimization of the enzyme electrodes were also examined.
