Description

Technical field [0001] The present invention belongs to the nanomaterial and antibacterial drug technology, and it is related to a nanomaterial comprising polyhydrate and a preparation method thereof. Background technique [0002] Infectious diseases caused by bacteria have become a fatal issue of human beings. Many conventional control strategies depend on antibiotics, metal ions and quaternary ammonium ions have been disadvantageous to ecological toxicity, high cost and environmental hazard. In addition, the increase in bacterial drug resistance is a serious threat to public health while promoting bacteria to produce a biofilm (biofilm is also known as biological film, refers to the lack of genus "with bacterial vented surfaces with life or without life. The organized bacterial population. Biofilm bacteria against antibiotics and host immune defense mechanisms are very resistant, there are various major biological macromolecules such as proteins, polysaccharides, DNA, RNA, pept...
