A Study on Ratio of Loss to Storage Modulus for the Blood Clot


Department of Chemistry, Materials and Chemical En, Politecnico Di Milano


In this study the rheology of blood clot is measured with the help of rotational rheometer. Several shear strain (0.5, 1 and 2%) are applied with two frequencies (5 and 10 Hz) from the incipient time of clot formation and the response of the sample is measured with the form of shear stress and the phase lag which is interpreted with storage and loss moduli. In this study the ratio of loss to storage modulus is studied and the blood clot gel-point as the transition from viscoelastic fluid to viscoelastic solid is investigated.
