Abstract
Methods and systems for creating patterns in tissue growth for tissue engineering are disclosed. In one embodiment, a method for arranging biological cells along predetermined patterns using an ultrasound includes: emitting the ultrasound by an ultrasound transducer; transmitting the ultrasound through a holographic lens toward a plurality of cells; and generating a pressure field in the predetermined patterns. The predetermined pattern includes a plurality of mutually parallel transverse planes. The parallel transverse planes are configured to entrap groups of cells of the plurality of cells. The axial pressure gradients within the parallel transverse planes are smaller than a first predetermined threshold. The lateral pressure gradients within the parallel transverse planes are larger than a second predetermined threshold. In response to generating the pressure field, the groups of entrapped cells are aligned within parallel transverse planes.
