Embodiment 1

[0033] Example 1: Preparation of Pt / TiO2 nanorod & silica ball micro-nanomotor.

[0034] A. Prepare the substrate:

[0035] Cut glass or silicon wafers into 1.5 cm×1.5 cm substrates, ultrasonically clean them for 5 min, and then clean them with a solution of deionized water, hydrogen peroxide, and ammonium hydroxide in a volume ratio of 5:1:1, and wait until the reaction When fully finished, discard the solution and rinse 5-10 times with deionized water. After checking and cleaning, blow dry with nitrogen and save for future use.

[0036] B. Preparation of monolayer silica pellets:

[0037] B-1. Clean the petri dish in advance: first ultrasonic cleaning for 5 minutes, then ultrasonic cleaning with acetone, alcohol, and deionized water in sequence, then rinse with deionized water, and finally blow dry with nitrogen.

[0038] B-2. Preparation of silica pellet solution in advance:

[0039]First, ultrasonically clean silica pellets with a diameter of 5 min, place them in a cen...

Abstract

The invention discloses a micro-nano motor and a preparation method thereof. The preparation method comprises the following steps that A, an underlayer is prepared; B, a monolayer silicon dioxide spherule is prepared; C, a nanorod is prepared; and D, a metal film layer is deposited. The prepared micro-nano motor comprises a monolayer silicon dioxide spherule thin film, a titanium dioxide or nickel nanorod with the length being 3.5 [mu]m and the diameter being about 500 nm and a platinum film layer with the thickness being 150 nm. The prepared micro-nano motor mainly takes the effects of catalyzing and self-assembling and can be applied to catalytic reaction accelerating, drug delivery and treatment in vivo and energy production and storage.

Description

technical field [0001] The invention relates to a micro-nano motor and a preparation method thereof, belonging to the technical field of material preparation. Background technique [0002] The research and development of functional micro-nano motors is an important scientific research task today, especially it can bring about major changes in the field of medical technology. In the field of medical technology, micro-nano motors can be used to locally transport therapeutic drugs, selectively remove certain diseased substances, or transmit information to the outside world at places that cannot be reached by ordinary medical devices. [0003] When a motor shrinks to the micron or even nanometer scale, the corresponding physical laws governing the motor's functions do not change, but the relative importance of various physical effects does change, for example, those related to the surface of the material and the viscosity of the fluid. Physical effects are much more important t...
