Description

technical field

[0001] The invention belongs to the technical field of medicine and hygiene, and in particular relates to a preparation method of an antibacterial agent containing nano-gold. Background technique

[0002] With the widespread use of antibacterial drugs, the treatment of infectious diseases has faced new challenges, and bacteria have developed resistance to antibiotics. Moreover, with the continued use of antibiotics, the problem of bacterial resistance will continue to increase. On the one hand, the drug resistance of bacteria will cause all kinds of antibiotics to lose their effect, and the growth and reproduction of bacteria will become more and more difficult to control; on the other hand, it will seriously endanger human health and even threaten human survival.

[0003] In 2014, China CHINET monitored the susceptibility and drug resistance of clinically isolated bacteria to commonly used antibacterial drugs in major domestic areas, showing that bacterial ...
