Acoustic‘Telekinesis’Precisely Steers Bacteria to Target Tumors for Cancer Therapy

摘要

Acoustic tweezers can control target movement through the interaction of momentum between an acoustic wave and an object.Due to their high tissue penetrability and strong acoustic radiation force,such tweezers overcome the limitations of optical and magnetic tweezers,thus making them suitable for in vivo cell manipulation.A research team led by Prof.ZHENG Hairong from the Shenzhen Institute of Advanced Technology(SIAT)of the Chinese Academy of Sciences(CAS)has recently developed a new type of acoustic tweezers—the phasedarray holographic acoustic tweezers(PAHAT)system—which is based on a high-density planar array transducer capable of generating tunable three-dimensional bulk acoustic waves.The researchers hope this system can realize a pharmacological version of“telekinesis.”
