US researchers have developed a new bioprinting technique that uses ultrasonic standing bulk acoustic waves (SBAW) to organize cells into controllable anisotropic patterns within viscous bioinks while maintaining high cell viability. This work represents a step forward in advancing bioprinting capabilities to achieve biomimetic tissue constructs.
