Comparison between Kinetics Studies of Protein Adsorption by Single-walled Carbon Nanotube and Gold Nanoparticles Surfaces

摘要

In this research, a Bovine Serum Albumin (BSA) experiment was carried out and the produced BSA used to investigate the adsorption behavior of BSA from aqueous solutions by single-walled carbon nanotubes (SWCNTs) and Gold Nanoparticles (GNPs) through UV-Vis spectroscopy. The change of the parameter of contact time was tested in several adsorption experiments. The kinetic data indicate that the adsorption fits well with the pseudo first-order kinetic model for BSA adsorbed by GNPs and for SWCNTs was intraparticle diffusion model.
