Abstract

The invention discloses a preparation method of a nano motor of a complex structure and belongs to the nano technical field. By applying ultrasonic treatment as an auxiliary preparation means, a driving plate drives a liquid to flow to generate a local flow field near a special array structure to capture near spheres which are assembled around the array structure. The structure of the prepared nano motor is primarily dependent on micro-scaled array structure which is processed by means of a photoetching technique, so that the nano motor has the characteristics of being high in precision, convenient to process and stable in structure. A customized design can be conducted according to the demands on material and working mode of the nano spheres.

Description

technical field [0001] The invention belongs to the field of nanotechnology, and in particular relates to a preparation method of a complex configuration nanomotor. Background technique [0002] Nanomotors refer to nanosystems that can convert chemical energy, light energy, sound energy, or other forms of energy into mechanical motion and complete complex tasks, and are often called nanorobots. It is essentially different from the traditional colloidal particles that are in thermodynamic equilibrium and only perform Brownian motion. Their movement and interaction can be compared to cells or bacteria in nature, so they are considered to be a new type of biomimetic smart materials and have attracted widespread attention. In recent years, nanomotors have gradually become one of the research hotspots and difficulties in related fields such as nanotechnology. Preliminary studies have shown that nanomotor research is expected to achieve revolutionary breakthroughs in the fields ...
