Abstract

The present invention relates to nano mesoporous and mesoporous-macroporous biological glass produced and through surfactant self-assembling and sol-gel process under mild reaction condition and possessing excellent bioactivity. The new type of biological glass has controllable mesoporous structure, homogeneous and adjustable mesopore distribution, relatively great specific surface area and porosity, macropores with adjustable size and porosity, and controllable shape. The present invention may be used as bone repairing material, dental material and rack material in tissue engineering and for medicine embedding and controlling releasing, etc.

Description

technical field [0001] The invention belongs to the technical field of biomaterials, and in particular relates to a nano-mesoporous and mesoporous-macroporous composite biological glass and a preparation method thereof. Background technique [0002] In the fields of biomaterials and medicine, bone defect repair has always been an important research topic. So far, people have studied a variety of bone defect repair materials, including artificial coral, animal bone, synthetic hydroxycarbonate, human tooth post-processing materials, and bioglass. Among them, biological glass is also a kind of artificial synthetic material, which is composed of silicon dioxide, calcium oxide, phosphorus pentoxide, and a small amount of Na 2 O, MgO, etc. This type of material has better osteogenic properties than hydroxycarbonated apatite, and also has superior biocompatibility and self-degradation properties. At present, bioglass has been certified by the US Food and Drug Administration (FDA...
