Abstract

The formation of adsorption layer of BSA aqueous solution under hydrodynamic lubrication conditions was studied using optical interferometry. The adsorption film was analysed and found consisting of two types of adsorption. A two-media approach was derived to determine the adsorption film thickness in real time.
