Abstract

The invention discloses a self-driven Au-Zn nano motor as well as a preparation method and application thereof. The self-driven Au-Zn nano motor is tubular, the length of the self-driven Au-Zn nano motor is 3-7 microns, the outer diameter of the self-driven Au-Zn nano motor is 320-500 nm, the inner diameter of the self-driven Au-Zn nano motor is 150-260 nm, the atomic percent of Au is 85-95%, and the atomic percent of Zn is 5-15%. No bubbles are generated in the pushing process of the motor, and the influence of the bubbles on the movement of the self-driven Au-Zn nano motor can be avoided. The interaction mode of the self-driven Au-Zn nano motor and the passive particles is switched between attraction and repulsion, a new thought can be provided for formation of tissue behaviors, aggregates and cell component clusters of active materials in biological evolution, and in addition, the self-driven Au-Zn nano motor can also be applied to biological molecule detection and biological information collection.

Description

technical field [0001] The invention belongs to the technical field of nanomotors, and in particular relates to a self-driven Au-Zn nanomotor and its preparation method and application. Background technique [0002] A nanomotor is a tiny device that can convert other forms of energy into kinetic energy, realize its own movement in a liquid medium, and perform complex tasks at the same time. According to the energy source driven by the nanomotor, it can be divided into a chemical energy-driven type generated by a chemical reaction or an external physical energy-driven type (light energy, sound energy, magnetic energy, electric energy) nanomotor. Chemical energy-driven nanomotors are nanomotors that provide energy through chemical reactions. Currently, H 2 o 2 , HCl, N 2 h 4 , I 2 etc. There are many reports on fuels; physical energy-driven nanomotors refer to nanomotors driven by energy provided by external physical fields, such as light-driven nanomotors, sound-driven n...
