Nanodroplet-Mediated Intravascular Sonothrombolysis: Cavitation Study

By: L. Goel  n, H. Wu  n, B. Zhang n , J. Kim  n, P. Dayton  n, Z. Xu *, X. Jiang n 

Contributors: L. Goel  n, H. Wu  n, B. Zhang n , J. Kim  n, P. Dayton  n, Z. Xu *, X. Jiang n 

Event: 2020 IEEE 20th International Conference on Nanotechnology (IEEE-NANO)

TL;DR: The purpose of this study was to demonstrate the feasibility of using nanodroplets with the small aperture intravascular transducers, which would allow access to a wide range of locations, and to demonstrate that it was feasible to deliver nanodrplets mediated sonothrombolysis using the smallperture intrav vascular transducers.
