Abstract

The influence of pH on the interaction between horse heart ferricytochrome c (cyt c) and zinc oxide nanoparticles (ZnO NPs) has been studied by a small angle scattering as well as UV-vis and FTIR spectroscopy. The observations showed that the optimal pH for the association of protein with nanoparticles is in pH range 5.0-8.0. Almost no significant change in structure and thermodynamic stability of cytochrome c after the association with 60 nm ZnO NPs was performed by UV-vis and by a circular dichroism spectroscopy.
