In vivo acoustic and photoacoustic focusing of circulating cells [PDF]
Scientific Reports, 2016 AbstractIn vivo flow cytometry using vessels as natural tubes with native cell flows has revolutionized the study of rare circulating tumor cells in a complex blood background. However, the presence of many blood cells in the detection volume makes it difficult to count each cell in this volume. We introduce method for manipulation of circulating cells

Acoustic droplet vaporization is initiated by superharmonic focusing [PDF]
The Journal of the Acoustical Society of America, 2013 Acoustically sensitive emulsion droplets composed of a liquid perfluorocarbon have the potential to be a highly efficient system for local drug delivery, embolotherapy or for tumor imaging. The physical mechanisms underlying the acoustic activation of these phase-change emulsions into a bubbly dispersion, termed acoustic droplet vaporization, have not ...
