Problems solved by technology

However, some ruthenium complexes have poor water solubility. If they are directly introduced into the surface of titanium metal, more organic solvents need to be used, which will pollute the environment, and there may be solvent residues on the titanium metal, which will cause danger to patients.

Abstract

The invention discloses a method for preparing titanium metal with the antimicrobial and anticancer performance. The method includes the following steps that 1, a ruthenium complex is prepared; 2, by weight, 0.1-0.6 part of cyclodextrin is dissolved in 3.5-20 parts of water and evenly stirred, and then 0.5-1.5 parts of titanium metal is added and soaked for 20-60 min; 3, by weight, 0.2-1.2 parts of the ruthenium complex is added, and then the mixture is treated for 30-60 min with 15-30 kHz ultrasonic waves; 4, the titanium metal is taken out and dried. According to the method, due to the effects of the cyclodextrin and the ruthenium complex on the titanium metal, the titanium metal has the good antimicrobial and anticancer performance, the surface of the titanium metal is beneficial to growth of osteocytes, the incidence rate of complications caused by the titanium metal in an osseointegration operation is reduced, and a safer and more reliable material is provided for the osseointegration operation.

Description

technical field [0001] The invention relates to the technical field of materials for osseointegration surgery, in particular to a method for preparing titanium metal with antibacterial and anticancer properties. Background technique [0002] β-cyclodextrin is a class of macrocyclic compounds formed by connecting 7 D-glucopyranose units end-to-end through α-1,4 glycosidic bonds. Inside the molecule is a "V"-shaped hydrophobic cavity, showing a unique molecular recognition ability. As a commonly used material in osseointegration surgery, titanium metal is widely used clinically. However, a serious problem is the associated bacterial infection problem, which leads to the failure of a large number of transplant operations. At present, there have been some reports on improving the antibacterial ability of titanium metal, such as using antibacterial molecules such as antibiotics to improve the antibacterial effect of titanium metal. Recently, researchers have been working to im...
