Abstract :
A novel optical tensiometric method for analysing protein adsorption at liquid interfaces is presented here. The complexities of protein adsorption and desorption processes have been extensively studied and it has been shown that a relatively simple optical tensiometry procedure provides measurements that support those from profile analysis tensiometry (PAT) using sessile drops. Both tensiometry and PAT show the effect of polarity on the adsorption of BSA to different polymers. These processes are also seen during the removal of protein from the polymers.
