Biolubrication: Hyaluronic acid and the influence on its interfacial viscosity of an antiinflammatory drug

Research output: Contribution to journalArticle


The influence of an antiinflammatory drug on the interfacial viscosity of hyaluronic acid was discussed. The experimental platform was a home-built surface forces apparatus (SFA) modified to study the viscoelastic shear response of confined fluids as a function of frequency and shear rate. The results demonstrated that the drug not only thickened the near-surface adsorbed layer and enhanced the near-surface viscosity, but also altered the character of shear-thinning.
