It is a trace element---zinc
Micrometer is the unit of length. Usually micron zinc refers to the application aspect
But the key point is to distinguish between micron zinc and nanometer zinc. zinc. Because they are completely different, especially in the field of antibacterial
Size: micron gt; nanometer
Precipitation: micron zinc ≈0. Nano is easy to precipitate with the number of uses
Reasons:
1. Most of nano is also precipitated through the precipitation of ions to inhibit bacteria.
2. Because nanometer is too small, it is difficult to control it with current technology to prevent it from precipitating
P.S. Micron zinc is completely different. It can truly integrate with the material and inhibit bacteria by changing the physical properties of the material surface.
3. In terms of technology: Micron technology is 1,000 times more difficult than nanotechnology - Professor Luigi Costa (authoritative expert in the field of materials)
So in terms of application, micron zinc antibacterial is very expensive, and most of them It is only used in the implantation of medical artificial bones to solve the problem of postoperative infection
Supplement:
The trace element zinc is also one of the essential trace elements for the human body. 1
Zinc is also called the flower of life and the source of intelligence
Zinc supplementation plays an extremely important role in human growth and development, immunity, vitamins, etc.
