Abstract

U ovom radu provedena je sinteza nanočestica s ljuskom od cinkovog oksida i jezgrom od enzima ureaze. Sinteza nanočestica cinkovih oksida se provodila se u redestiliranoj vodi pri različitim koncentracijama cinka i uree pri temperaturi T = 25 °C uz istu koncentraciju ureaze. Kinetika brzine taloženja enzima ureaze opisana je kinetikom prvog reda za koju je utvrđeno da dobro opisuje gotovo sve reakcije. Istaložene nanočestice cinkovog oksida su karakterizirane pomoću optičkog mikroskopa.

Abstract (english)

In this study synthesis of core shell nanoparticles with the core of enzyme urease and the shell of zinc was carried out. The synthesis of zinc oxide nanoparticles was carried out in redistilled water with different concentrations of zinc and urea at temperature T = 25 °C, and with the same concentration of urease. The rate of enzyme precipitation was described by the first order kinetics. This kinetic described well almost all experiments. Synthesized zinc oxide nanoparticles were characterized using the optical microscope.
