Ultrasound-assisted biofabrication

Non-invasive manipulation of tissue spheroids for artificial creation of organs and vessels

Biofabrication is the process of artificially creating organs and biotissues from cells and tissue spheroids. Currently, one of the most crucial issues in biofabrication is vascularization of artificial organs, i.e., creating thin hollow vessels for them.

Ultrasound is able to contactlessly manipulate objects using acoustic radiation force. Therefore, a combination of acoustic and magnetic fields makes it possible to contactlessly organize cells into hollow tubes to create artificial vessels.
