Problems solved by technology

For example, the requirements of the mold pressing method on the target charge structure and the mechanical strength of the target charge structure make it difficult to realize special-shaped charges and ensure the consistency of charges; After the charge is completed, the volatilization of the solvent will form internal cavities in the charge column, resulting in unreliable charge density, etc.

Abstract

The invention belongs to the field of micro-charging, and in particular relates to a micro-scale special-shaped charging method based on an electrostatic template. The method adopts an electrostatic spraying device, and the raw material is a target drug precursor, and the target drug precursor moves to the special-shaped charge template under the action of an electric field, and gathers in the area where the special-shaped charge template is electrically conducted. The special-shaped charge method based on electrostatic template takes advantage of the good dispersion and fluidity of energetic particles in the solution environment and the characteristics that charged particles will gather to the conduction area of ​​the electric field in the electric field, and vertically deposit the target agent on the special-shaped micro-device superior. The method can effectively ensure the uniformity of the special-shaped charges, and the device has a simple structure and a wide range of applications, and can realize directional and orderly charge under the action of a certain driving force.
