Application in the medical field.
(1)Porous magnesium tissue engineering scaffold
As a biodegradable biomaterial, porous magnesium can provide three-dimensional growth space for cells and facilitate the exchange and transportation of nutrients and metabolites. As a bioactive material, porous magnesium can induce cell differentiation and growth and vascular growth.
(2)Stents
Biodegradable endovascular scaffolds made of magnesium and its alloys were fabricated in the human body.
After life will gradually degrade and disappear, without the need for patients to take medicine for a long time, which will greatly reduce the pain and financial burden of patients.
(3)Bone implant material
The advantage of magnesium and its alloys as bone fixation materials is that they are close to human bone density and mechanical properties, which can effectively reduce the stress shielding effect. At the same time, the alkaline environment in which magnesium is degraded can play an antibacterial role.
Magnesium has a good compatibility with bone tissue, and it also plays a role in promoting vascularization. More and more advantages of magnesium are being discovered, so it can be said that magnesium and its alloys have great potential as bone fixation materials. The following figure shows some magnesium alloy bone implant devices developed by institute of metal research, Chinese academy of sciences.
