<p>“So we are developing this ultrasound printer, which uses ultrasound waves to convert the sono-ink developed by Shirke’s lab into three-dimensional structures actually inside the tissue without the need to print it out, then implant it into the tissue,” Yao was quoted as saying by STAT News.</p>
