Light-driven nanomotor of janus structure

Abstract

The invention relates to a light-driven nanomotor of a janus structure. A main body of the light-driven nanomotor comprises working substances, metal films are evaporated on partial surfaces of the working substances, therefore, the janus structure partially covering the working substances is formed, and the working substances of the surplus surfaces can have a lighting decomposition reaction to generate air driving force. The light-driven nanomotor of the janus structure has the advantages that the light driving mode is extremely simple, convenient and controllable; a preparation method of the nanomotor is also relatively simple; the light-driven nanomotor is not limited by a solution environment, the motion direction has the controllability, and fast and accurate directional carry is hopefully achieved.

Description

technical field [0001] The invention relates to a machine applied in the field of light-driven micro-nano transport, in particular to a light-driven nanomotor with a double-faced god structure. Background technique [0002] A nanomotor is a nanomachine that can use the energy in the environment, such as chemical energy, magnetic energy, electrical energy, etc., and convert it into motion energy. Comprehensive nanomotor research progress found that it has the following characteristics: (1), the characteristic size is small, between microns and nanometers; (2), light weight, large thrust-to-weight ratio (the maximum thrust-to-weight ratio can reach more than 200); (3) , Low power consumption, consumes material energy in the solute. This kind of tiny and controllable transportation machinery will surely create a new pattern in various fields. [0003] Whitesides was the first to start the study of self-propelled macrostructures. He installed a platinum strip as a catalyst in ...

AI Technical Summary

Problems solved by technology

[0008] The research on nanomotors is still in its infancy, and a complete research system has not yet been formed. There are still many key issues to be solved before the actual application: (1) The working environment of the motor is limited; (2) The preparation process is complicated and not suitable for large-scale Promotion; (3), the motor movement direction is relatively random, which creates difficulties for practical application

[0009] The existing results cannot meet the needs of people's practical applications, so there is an urgent need for a nanomotor with a working environment that is not limited to a certain solution, simple preparation, and good controllability

At present, there is no nanomotor driven by light to achieve directional motion in the literature
