Problems solved by technology

In the pharmaceutical industry, stainless steel can be used to prepare bone plates, bone nails and other orthopedic materials, but stainless steel has poor biocompatibility and does not have the ability to resist bacterial invasion, resulting in the failure of a large number of orthopedic operations
At present, the methods used to improve the antibacterial ability of stainless steel include the use of silver compounds, antibiotics, etc., but these methods have defects, such as excessive release of silver will show toxicity

Abstract

The invention discloses a stainless steel material. A ruthenium complex modifies the surface of the stainless steel material. The structural formula (I) of the ruthenium complex is shown in the specification. The invention further discloses a preparation method and application of the stainless steel material. According to the invention, on the basis of the recognition ability of the ruthenium complex to calf thymus desoxyribonucleic acid, the ruthenium complex modifies the surface of the stainless steel material, and therefore the obtained stainless steel material is high in ability to resist bacteria and cancers.

Description

technical field [0001] The invention relates to a stainless steel modified by a ruthenium complex, a preparation method and application thereof. More specifically, the present invention relates to ruthenium complex-modified stainless steel obtained by utilizing the recognition function of ruthenium complex calf thymus deoxyribonucleic acid, as well as its preparation method and application. Background technique [0002] Stainless steel has excellent chemical properties, physical properties, mechanical properties and process properties, chemical corrosion resistance, heat resistance, high temperature resistance, low temperature resistance, oxidation resistance, and is widely used in many fields. In the pharmaceutical industry, stainless steel can be used to prepare bone plates, bone nails and other orthopedic materials, but stainless steel has poor biocompatibility and does not have the ability to resist bacterial invasion, resulting in the failure of a large number of orthop...
