BSA, adsorption, nanoparticles

Adsorption of BSA on nanoceria can be described by Langmuir adsorption theory, using linear regression were calculated maximum adsorption capacities. Thus, the equilibrium constant of adsorption could be calculated from the Langmuir binding constant b. It was proved that the adsorption capacity of BSA on nanoceria particles increased (for pH 4) with a rise in temperature. Calculated thermodynamic parameters indicate that the adsorption of BSA on the ceria is endothermic (?Hads > 0) and non-spontaneous (?Gads > 0) process. The kinetics of adsorption fitted best to pseudo-second-order. Further measurement is necessary to explain the mechanism of BSA adsorption on NPs.
