Description

technical field

[0001] The invention belongs to the technical field of material science, and in particular relates to a composite microsphere containing hydroxyapatite and a preparation method thereof. Background technique

[0002] Hydroxyapatite is one of the most researched bioactive materials at present. It is widely used in various bone repair materials, cells and drug carriers, and it is also used in inhibiting cancer cells. However, hydroxyapatite itself is very brittle, difficult to form, and slightly soluble in water. There are few literature reports on hydroxyapatite microspheres, which largely limits its application.

[0003] Alginate is a kind of natural polysaccharide polymer, which is non-toxic and biodegradable. Sodium alginate has attracted much attention because of its gelation in the presence of multivalent cations, and has been widely used in food, cosmetics, and biomedicine. a wide range of applications. Alginate microcap...
