Abstract

The invention discloses a dynamic controlling method of a micro-nanometer motor cluster. The dynamic controlling method comprises the following steps: dispersing TiO2 micro-nanoparticles into hydrogenperoxide solution, and putting between two electrode base plates; connecting the electrode base plates with alternating current, forming a TiO2 micro-nanometer motor cluster on a part close to the surfaces of the electrode base plates and controlling a form and the size of the TiO2 micro-nanometer motor cluster by regulating voltage and frequency of the alternating current; realizing driving of the TiO2 micro-nanometer motor cluster by controlling the direction and strength of illumination. According to the method disclosed by the invention, the problems that a controlling method and a function of the micro-nanometer motor cluster is single, and control of a cluster motion behavior is limited in the prior art are overcome, dynamic control of the form of the micro-nanometer motor cluster is provided, and a controlling method of high spatial and temporal resolution of the motion behavior can be realized.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a dynamic control method for a cluster of micro-nano motors. Background technique [0002] Micro-nanomotor is a micro-device that converts other energy into kinetic energy and can complete various complex tasks in liquid media, including drug transport, protein and cell separation, and environmental governance (NanoToday2013,8(5):531-554 ; ACS Nano 2012, 6(7), 6122-6132; SoftMatter 2011, 7(18), 8169-8181). Since the synthesis of micro-nano motors was reported in 2004, many significant advances have been made in the field of mechanism research and development and application of micro-nano motors (J. Am. Chem. Soc. 2004, 126, 13424-13431). Similar to the protein assembly of organisms, the assembly of simple individual micro-nano motor units into complex "cluster" structures is one of the necessary conditions for the multifunctional application of micro-nano motors (A...
