Magnetic-acoustic actuated spinous microrobot for enhanced degradation of organic pollutants.

ABSTRACT: A growing interest in the development of efficient strategies for the removal of organic pollutants from polluted water is emerging. As such, artificial micro/nano machines performing excellent water purification tasks have recently attracted more research attention of scientists. Hereby a spinous Fe₃O₄@PPy microrobot is presented that towards an efficient organic pollutant removal by enhancing Fenton-like reaction. The microrobot is fabricated by wrapping polypyrrole (PPy) on a spiny magnetic template prepared from sunflowers pollen. Modulating the sound pressure and frequency of the ultrasonic field enables the Fe₃O₄@PPy microrobot to present multimode motion, such as violent eruption-like motion caused by local cavitation (ELM), march-like uni
