Abstract

The invention discloses a hydroxylapatite-bioglass film, which is prepared by taking hydroxylapatite or bioglass or the mixture of both as a target material and using the following technology of: adopting pulse laser with energy density of 5J-cm to complete the sedimentation of the film in an argon atmosphere with underlayer temperature of 15 DEG C to 600 DEG C and pressure of 5Pa to 45Pa or an oxygen atmosphere with pressure of 1*10-9*10Pa and under the condition with pulse number of 3,000-18,000. The bio-film has no cytotoxic effect and good biocompatibility, causes no hemolytic reaction and acute systemic toxicity effect, imposes no obvious inhibition on the growth and proliferation of cells, generates no toxic action to laboratory animals, and meets the requirements for biological safety.

Description

technical field [0001] The invention relates to a hydroxyapatite-biological glass film and a preparation process thereof. Background technique [0002] Biomedical materials (Biomedical Materials) refer to new materials used to combine with living systems to diagnose, treat, repair or replace damaged tissues and organs of living organisms or enhance their functions. As an important part of biomedical material research, the research on human implant materials has developed rapidly in recent decades, especially in the past two decades, and has become a focus in current medical research. [0003] At present, a variety of implant materials have been used clinically. Hydroxyapatite (HA) has become one of the most widely used clinical implant materials because of its good biocompatibility and bioactivity, and is widely present in hard tissues such as animal bones and teeth. However, the strength and toughness of bulk hydroxyapatite are poor, so it cannot be applied to the bearing...
