Description

technical field

[0001] The invention belongs to the technical field of biomedical materials, in particular to a graphene / calcium phosphate ceramic composite stent with antibacterial function and a preparation method. Background technique

[0002] Calcium phosphate bioceramics have been widely used in the field of bone repair due to their excellent biological effects such as good biocompatibility, osteoconductivity, and osteoinductivity. Bone defects caused by clinical trauma are often accompanied by wound contamination or infection symptoms, and conventional bone repair materials often fail due to secondary infection. With the increasing clinical problem of bacterial drug resistance, higher requirements have been placed on the antibacterial properties of bone repair materials. Therefore, on the basis of optimizing the osteoinductive ability of calcium phosphate ceramics, it is of great significance to optimize the modification method to make it have both antibacterial prope...
