Abstract

Blood related diseases and bleeding are responsible for a large number of deaths globally every year. Over 1000 women die as a consequence of pregnancy related complications daily and over 50% of these deaths are related to excessive bleeding [1]. In recent years, there has been a growing interest to study blood coagulation and the development of nano-mechanical diagnostics using acoustic techniques. Here we show the manipulation of blood’s rheological properties using surface acoustic waves (SAW). Contrary to the normal shear thinning behavior of blood at high shear rates [2], the application of SAWs results in shear thickening.
