Annotation Composite materials based on nanocrystalline (100 nm) stoichiometric hydroxyapatite (HA) and calcium deficient HA increased chemical and biological activity in the process of recovery of the affected bone, since HA are the main inorganic components of bone. Sodium alginate is a polymer of natural origin, which has many applications in biomedical science and tissue engineering due to its properties: biocompatibility, hydrophilic, non-immunogenic properties, ability to stimulate osteoplastic processes, ease of gelation. Since alginate gels retain structural similarity to the extracellular matrix of the body, they are especially attractive for wound healing, drug delivery. In the composition of composite materials, it is possible to replace the elastic properties of bone tissue alginate in combination with the mechanical properties of HA and activate the mechanisms of bone tissue regeneration in vivo.The current state of research and the use of biomaterials based on hydroxyapatite and alginate in medicine, pharmacology and tissue engineering are demonsteted in this article.
