Abstract

The invention discloses a method for preparing stainless steel with antibacterial and anti-cancer properties by means of a rhodium complex. The method comprises the following steps that 1, the rhodium complex is prepared; 2, 0.1-0.6 part by weight of cyclodextrin is dissolved in 3.5-20 parts by weight of water, even stirring is conducted, 0.5-1.5 parts by weight of stainless steel is added, and soaking is conducted for 20-60 min; 3, 0.2-1.2 parts by weight of rhodium complex is added, ultrasonication is conducted for 30-60 min at 15-30 kHz; 4, the stainless steel is taken out and dried. According to the method for preparing the stainless steel with the antibacterial and anti-cancer properties by means of the rhodium complex, by means of the action of the cyclodextrin and the rhodium complex on the stainless steel, the stainless steel has good antibacterial and anti-cancer properties, the surface of the stainless steel facilitates growth of bone cells, the morbidity of complications caused by the stainless steel in an osseointegration operation is decreased, 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, more specifically a method for preparing stainless steel with antibacterial and anticancer properties by using rhodium complexes. Background technique

[0002] γ-cyclodextrin is a kind of macrocyclic compound formed by connecting 8 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, stainless steel 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. Recently, researchers have focused on improving the antibacterial and other capabilities of stainless steel. How to obtain stainless steel materials with better properties has become a research direction with great scientific and...
