A kind of biomedical antibacterial agent with hydrophobicity

Abstract

The invention relates to the field of biomedical antibacterial. A hydrophobic biomedical antibacterial agent, by weight, add 1-3 parts of organosilicon monomer into a 50ml beaker, and add 10 parts of solvent, ultrasonic for 30 minutes and stir for 10 minutes; 5 parts of graphene quantum dots are coated The nano-silver antibacterial agent was placed in a 50ml beaker, and 10 solvent was added, and ultrasonicated for 30 minutes; the solution of the organosilicon monomer was added to the prepared graphene quantum dot-coated nano-silver antibacterial agent dispersion, and stirred for 90 minutes; the prepared hydrophobic The silanized graphene quantum dot-coated nano-silver antibacterial agent dispersion is cooled at room temperature and dried to obtain a biomedical antibacterial agent with good antibacterial and hydrophobic properties.

[0001] The invention relates to the field of biomedical antibacterial. Background technique

[0002] With the progress of society and the development of medicine, catheters have been widely used in the medical field. A common problem faced by various catheters in use is that infection is prone to occur in the implanted body, and the infection caused by long-term indwelling catheters is particularly serious. This kind of infection, on the one hand, prolongs the recovery time of patients and increases the chance of complications, on the other hand, it also causes an increase in medical expenses and a waste of medical resources. In order to avoid the occurrence of various infections and reduce the cost of patients, it is necessary to solve this problem from the source, that is, to endow the catheter itself with durable and excellent antibacterial properties to reduce the occurrence of infection.
