Abstract
Layered Double Hydroxides (LDHs) are layered compounds composed of a positively charged main layer and interlayer anion assembled by non-covalent bond interaction. The chemical composition of the main lamella in LDHs can be modulated, as can the type and quantity of interlayer anions so that the particle size and distribution of its intercalated assembly can be regulated. Because of its unique physical and chemical properties, it can treat or repair the human body by acting as a drug carrier, introducing antibacterial ions, and as a therapeutic material. Therefore, it has great application prospects in the biomedical field. This paper will briefly describe the preparation method of LDHs and give an example of a specific process for LDHs. After that, this paper will review the application of LDHs in tumor treatment, antibacterial effect, and bone repair and summarize the progress of the application of LDHs in the biomedical field, as well as the opportunities and challenges faced.
