Gold nanometer wafer

Abstract

The invention discloses a gold nanometer wafer, and belongs to the technical field of a nanometer wafer. The gold nanometer wafer comprises a silicon substrate, wherein microneedles are arranged on the silicon substrate; each microneedle comprises an upper section and a lower section; the upper section of the microneedle is in a cylindrical shape; the lower section of the microneedle is in a pointed cone shape; a groove is formed in each microneedle; and a gold layer is plated on the outer wall of each microneedle. The gold nanometer wafer has the advantages that by using an independent research and development technology, 99.999-percent gold materials are combined with 99.999-percent monocrystalline silicon materials; through a fine engraving process, the nanometer level microneedles areintegrated onto the wafer; the use effect is obvious; and effective active substances can be conveyed to positions above the stratum basale, so that the seepage of a skin care product is greatly enhanced, and the skin care product fast works; and the corium layer, nerves and blood vessels cannot be touched, so that no harm is caused on the skin.

Description

technical field [0001] The invention relates to the technical field of nano-chips, in particular to a gold nano-chip. Background technique [0002] Nanochip is a special tool for nano-penetration enhancement developed according to the structure of human skin. It is carved from single crystal silicon through nanotechnology. The surface of nanochip is a series of microneedle arrays, which can open the outermost stratum corneum of the skin. At the same time, it will not hurt the dermis, greatly improving the penetration of nutrients, and the biocompatibility of monocrystalline silicon ensures the safety of nanocrystals during use. However, the current nanochips are less safe in use and will affect people Causes a certain degree of pain, takes effect slowly, and the effect of use is not obvious, and most of the microneedles used have the disadvantages of not being sharp enough at the tip and easy to break.
