Surface| Zusammenfassung: | The reaction of hydrolytic co-polycondensation of tetraethoxysilane, 3-aminopropyltriethoxysilane and methyltriethoxysilane was used to synthesize bifunctional silica microspheres. Urease was immobilized on the surface of the obtained carriers via adsorption. In order to compare, urease was also immobilized by inclusion during the reaction of hydrolytic polycondensation of alkoxysilanes. It was determined that the highest degree of binding (99%) and residual activity (18%) are observed when urease is immobilized by inclusion. |
