Problems solved by technology

The methods used above all have their own characteristics, but the microtubes prepared by these methods all have a single-layer structure. In addition, the surface of the metal oxide microtubes is still the chemical composition of the metal oxide itself. Although it is not biologically toxic, it is not compatible with the human body. There are differences in the chemical composition of tissues, and they do not have the ability to guide or induce the regeneration of human tissues
