selectivity control through microkinetic analysis of complex catalytic reactions



Immobilization of glucose oxidase and polyphenol oxidase in poly(N-(4-(3-thienyl methylene)-oxycarbonylphenyl) maleimide)-co-pyrrole) matrice
Çil, Mahmut; Toppare, Levent Kamil; Department of Chemistry (2006)
In this study, glucose oxidase and polyphenol oxidase were immobilized in conducting copolymer poly(N-(4-(3-thienyl methylene)-oxycarbonylphenyl)maleimide)-co-pyrrole(P(MBThi-co-Py)). A copolymer was electrochemically synthesized by using sodium dodecyl sulfate (SDS) as supporting electrolyte and characterized by FTIR, scanning electron microscopy (SEM) and conductivity measurements. Immobilization of glucose oxidase (GOD) and polyphenol oxidase (PPO) enzymes were performed in conducting PPy and P(MBThi-co-...

Immobilizing cholesterol oxidase in chitosan-alginic acid network
Yapar, Elif; Kayahan, Senem; Bozkurt, Ayhan; Toppare, Levent Kamil (Elsevier BV, 2009-04-09)
Proton conducting biopolymer networks have potential use for bio-sensors. The cost-effective, non-hazardous and environmentally safe biopolymer, such as chitosan, is an attractive feature for bio-sensors. Cholesterol oxidase was immobilized in conducting network via complexation of chitosan with alginic acid. A method for the preparation of the complex along with characterization by elemental analysis, FTIR spectroscopy, TGA and DSC were reported. The proton conductivity chitosan-alginic acid network was st...
Selective chromogenic response via regioselective binding of cations: a novel approach in chemosensor design
Ataman, D; Akkaya, EU (2002-05-27)
A calixdiquinone bis-indoaniline derivative with two kinds of potential binding sites, discriminates cations according to their charge/size ratio. Harder and highly oxophilic Eu(III) preferentially interacts with the lower rim quinone oxygens; whereas Na(I) binds to the azacrown moieties. As a consequence of the chromogenic sensor s design, these two binding events result in two different responses, Eu(III) causes a remarkable auxochromic change, but Na(I) produces a significant anti-auxochromic effect.
Immobilization of tyrosinase in polysiloxane/polypyrrole copolymer matrices
Arslan, Ahu; Toppare, Levent Kamil; Department of Chemistry (2006)
Immobilization of tyrosinase in conducting copolymer matrices of pyrrole functionalized polydimethylsiloxane/polypyrrole (PDMS/PPy) were achieved by electrochemical polymerization. The polysiloxane/polypyrrole/tyrosinase electrode was constructed by the entrapment of enzyme in conducting matrices during electrochemical copolymerization. Maximum reaction rate (Vmax) and Michaelis-Menten constant (Km) were investigated for immobilized enzyme. Enzyme electrodes were prepared in two different electrolyte/solven...
