Fluid synthesis preparation device for preparing Fe3O4 magnetic nanoparticles, and control method thereof

Abstract

The invention relates to a fluid synthesis preparation device for preparing Fe3O4 magnetic nanoparticles, and a control method thereof. The defect that devices capable of preparing the Fe3O4 magneticnanoparticles do not exist in the prior art is overcome. The device comprises a first micro-reaction chamber assembly and a second micro-reaction chamber assembly, the first micro-reaction chamber assembly comprises a first micro-reaction chamber, the upper end of the first micro-reaction chamber is connected with an ethylene glycol supply tube, the bottom of the first micro-reaction chamber is funnel-shaped, the first micro-reaction chamber is placed on a magnetic stirrer, a sieve plate is arranged in the first micro-reaction chamber, a magneton is placed on the sieve plate, the front end ofa silicone tube is connected to the bottom of the first micro-reaction chamber, and the tail end of the silicone tube is connected to the upper end of the second micro-reaction chamber assembly. The preparation device capable of synthesizing the Fe3O4 magnetic nanoparticles cooperates with the fluid control method based on a pump valve to realize automatic preparation of the Fe3O4 magnetic nanoparticles.

Description

technical field [0001] The invention relates to the technical field of chemical preparation devices, in particular to a method for preparing Fe 3 o 4 A fluid synthesis preparation device for magnetic nanoparticles and a control method thereof. Background technique [0002] Fe 3 o 4 Magnetic nanoparticles are a common superparamagnetic nanomaterial, which has the characteristics of magnetic conductivity and nanomaterials, and also has the advantages of simple preparation, low toxicity, and good biocompatibility, so it is widely used in clinical diagnosis, Contrast imaging, targeted drugs, biomarkers and separations, etc. [0003] In order to obtain monodisperse, uniformly sized Fe 3 o 4 Nanoparticles, generally adopt the hydrothermal method, that is: add trisodium citrate, anhydrous sodium acetate and other reagents in turn to ferric chloride dissolved in ethylene glycol, stir for half an hour to fully dissolve them; Transfer to a reaction kettle, place in an oven at 2...

AI Technical Summary

Problems solved by technology

[0004] It can be seen that the preparation and cleaning process of the traditional artificial chemical method is cumbersome, consumes a large amount of reagents, and the cycle is long, and the synthesis of nanoparticles with uniform size depends on the experience of the operator, which is not convenient for batch synthesis and use.
