چکیده انگلیسی


- Fe3O4 nanoparticles were synthesized, characterized and used for protein adsorption.
- SiO2, CNTs and graphene were used for covering the readily synthesized magnetite NPs.
- Adsorption kinetics and capacities of nanostructures were elucidated.
- SiO2 coated nanoparticles showed the fastest kinetics and capabilities for Ly and BSA adsorption.

In this study, differently coated superparamagnetic Fe3O4 (magnetite) nanoparticles were synthesized, characterized and used for lysozyme (Ly) and bovine serum albumin (BSA) adsorption. SiO2, carbon nanotubes (CNTs) and graphene were used for covering the readily synthesized magnetite nanoparticles to elucidate the effect of cover layer on the protein adsorption kinetics and capacities of nanostructure. XRD, FTIR, AFM, SEM, VSM and fluorescence measurements were used for the characterization of the samples and investigating the adsorption kinetics of Ly and BSA by these nanoparticles. The average particle size of the Fe3O4 nanoparticles are approximately found as 10 nm and VSM measurement shows that the Fe3O4 particles have superparamagnetic behavior with no hysteresis and remnant. The adsorption kinetic of proteins on nanosized material is followed via fluorescence method. All the nanostructures with different cover layers obey pseudo first order kinetics and SiO2 coated nanoparticles show the fastest kinetics and capabilities for Ly and BSA adsorption.
