Holographic acoustic manipulation

This work aims to realize programmable manipulation for living cells and micro-organisms in a common Petri dish by using holographic acoustic tweezers. Based on a self-developed 2D ultrasound matrix array, we successfully synthesize various complex acoustic fields and achieve the precise regulation of the fields both in space and time, and further build a holographic acoustic tweezer system compatible with microscopic imaging. This system innovatively realizes multidimensional translation, rotation, orientation, and levitation of living cells and micro-organisms, thereby demonstrating their value for advancing research in the fields of cell assembly, tissue engineering, and micro-robot driving. read more
