The application belongs to the technical field of biological
medicine, and particularly relates to a
drug for treating scald infection and a preparation method and application thereof. The application prepares a
drug for treating scald infection, which is self-assembled from a tetrahedral framework
nucleic acid and an antibiotic. The application preferably selects a tFNAs-NeoS
drug, the drug has a simple preparation method, a
high loading efficiency of
neomycin sulfate, good stability in a complex biological medium, reduced
cytotoxicity and effective
dose of the antibiotic NeoS, better
biological safety than tFNAs, and slowed generation of bacterial
drug resistance. In terms of treating scald
wound infection, the tFNAs-NeoS has better effects of promoting
wound healing and
biological safety than NeoS. Therefore, the prepared tFNAs-NeoS overcomes the problem of overuse of
antibiotics, and has a good clinical application prospect.
