Problems solved by technology

However, most of the current surface modification methods have single functions, which can only satisfy the process of promoting osteogenesis or inhibiting osteoclastosis, and cannot effectively regulate the response behavior of osteogenesis and osteoclastosis, which will affect the healing of bone injuries and even regenerate bone.

Abstract

The invention provides a method for constructing a coating for bidirectional regulation of response behaviors of osteoblasts and osteoclasts, comprising the following steps: substrate pretreatment; alkali activation treatment; configuration of organic phosphonic acid mixed solution; and construction of a bidirectional regulation functional coating. It also includes a bidirectional regulation osteoblast and osteoclast response behavior coating prepared by the above construction method. The invention optimizes the content ratio of polyphosphonic acid and bisphosphonic acid molecules, and the used polyphosphonic acid molecules and bisphosphonic acid molecules are respectively helpful to promote osteogenesis and inhibit osteoclastosis, obtain high-quality coatings, and achieve multiple The release of an organic phosphonic acid can be controlled to realize the bidirectional regulation function.

Description

technical field [0001] The invention belongs to the technical field of cell response behavior coating components, and in particular relates to a bidirectional regulation osteoblast and osteoclast response behavior coating and a construction method thereof. Background technique [0002] Bone injury is the main cause that affects the quality of life of human beings, and the number of patients is on the rise with the influence of population aging. Currently, implant intervention is an effective means of treating bone injuries. However, the biofunctionalization of most implant surfaces is insufficient to promote bone remodeling at the damaged site, and the long healing period of bone damage will bring economic and psychological burdens to patients. Therefore, it is urgent to make the surface of bone implant materials have osteogenic function through surface modification. [0003] At present, the most widely used method of surface modification of implant materials is to carry b...
