The aim of the CARIBBBOU project is to design and implement a real-time signal feedback forcavitation control to facilitate ultrasound-based gene therapy or drug delivery, with a particular focus on theBBB opening. Two specific devices will be designed for the following applications: (i) in-vitro: theidentification of the biophysical mechanisms underlying ultrasound and cavitation-facilitated uptake in cellsand BBB opening (using mimicking cell lines), and (ii) in-vivo: the enhancement of the BBB opening and thepenetration of therapeutic genes.CAvitation Regulation In-vivo: application to the Blood Brain Barrier Opening by Ultrasound
