preparation example Construction

[0025] The invention provides a method for preparing an anti-tumor nanorobot, comprising the following steps:

[0026] a) The iron target is placed in the sputtering chamber, feed argon and oxygen into the sputtering chamber, start the sputtering chamber power supply and carry out magnetron sputtering; in the process of magnetron sputtering, the cavity temperature of the sputtering chamber 800~1200℃;

[0027] b) After the magnetron sputtering is finished, maintain the cavity temperature of the sputtering chamber at 800-1200°C, and feed acetylene gas into the sputtering chamber;

[0028] c) After passing the acetylene gas, pass the protective gas into the sputtering chamber, and reduce the cavity temperature of the sputtering chamber to 100-300° C. within 5-15 minutes to obtain an anti-tumor nanorobot.

[0029] In the preparation method provided by the present invention, an iron target is first placed in a sputtering chamber. Among them, the iron target is preferably iron oxi...

Embodiment 1

[0038] The preparation of anti-tumor nanorobots comprises the following steps:

[0039] 1) Cleaning: First wipe the glass workpiece fixture with alcohol, then put it into an ultrasonic cleaner, super-wash with deionized water, and super-clean with alcohol, and finally put the workpiece fixture in alcohol steam for drying. When the workpiece fixture is cleaned by steam When taken out, the workpiece holder can be dried quickly because the condensed steam evaporates from the surface;

[0040] 2) Paste the protective film: paste the cleaned workpiece fixture with polyethylene film to protect the cleanliness of the workpiece fixture and protect the workpiece fixture from damage;

[0041] 3) Install the film-attached workpiece fixture on the running track of the magnetron sputtering device, and tear off the protective film before entering the film feeding chamber;

[0042] 4) The working fixture moves to the film feeding chamber of the magnetron sputtering device, then closes the v...

Abstract

The invention belongs to the field of nano materials, and particularly relates to a preparation method of an anti-tumor nano robot. The anti-tumor nano robot comprises the following steps that (a) an iron target is placed in a sputtering chamber, argon and oxygen are introduced into the sputtering chamber, and a power supply of the sputtering chamber is started to carry out magnetron sputtering; during the period, the temperature of the sputtering chamber is 800-1200 DEG C; (b) after the magnetron sputtering is finished, the temperature of the sputtering chamber is maintained at 800-1200 DEG C, and acetylene is introduced into the sputtering chamber; and (c) after acetylene introduction is finished, protective gas is introduced into the sputtering chamber, and the temperature of the sputtering chamber is rapidly reduced to 100-300 DEG C to obtain the anti-tumor nano robot. Experimental results show that the saturation magnetization intensity of the anti-tumor nano robot prepared by the method is 19-20 emu / g, the residual magnetization intensity is 4-5 emu / g, the coercive force is 550-600 G, the particle size is 70-100 nm, the particle size uniformity is less than 6.5%, the purity is greater than 99.9%, and the graphitization degree is greater than 90%.

Description

[0001] This application claims the priority of the Chinese patent application with the application number 201911113679.4 and the title of the invention "Preparation method of anti-tumor nanorobots" submitted to the China Patent Office on November 14, 2019, the entire contents of which are incorporated by reference in this application . technical field [0002] The invention belongs to the field of nanometer materials, in particular to a preparation method of an anti-tumor nanorobot. Background technique [0003] Tumor tissue is actually a complete ecosystem formed by tumor cells and tumor blood vessels, which not only contains tumor cells, but also has abundant tumor blood vessels inside. Modern biomedical research has proved that there are huge differences in the structure of tumor blood vessels and normal blood vessels. Generally speaking, it takes a year for normal blood vessels to grow, which is a three-layer dense structure composed of intima, media and adventitia, whi...
