Abstract
Investigating the mechanical properties of biological media over several scales is important for our fundamental understanding of complex biological processes. In this paper, an active microrheology approach for viscoelastic media is proposed, which relies on the use of acoustical tweezers to force individual microbubbles and the ultrasound localization of its induced displacement. Our study shows that a good localization accuracy is achieved and can resolve displacements that are typically observed under acoustic forcing experiments.
