ABSTRACT
BACKGROUND: The development of nanomaterials provides a good guarantee for the development of biomedicine. Nano-clay Laponite is a synthetic nanomaterial with excellent properties. It is widely used in drug delivery, tissue regeneration, three-dimensional biological printing and other fields. OBJECTIVE: To summarize the latest application status and future research prospect of nano-clay Laponite. METHODS: With the key words of “nano-clay, clay, Laponite” in English and Chinese, we searched CNKI, Wanfang, China Biomedical Database and PubMed. We further screened and summarized. RESULTS AND CONCLUSION: Laponite has unique rheological properties, electrical conductivity, antibacterial properties, organization, good biocompatibility and other excellent properties, has been widely used in the fields of chemical industry, drug delivery, and regenerative medicine. It is a kind of nanomaterial with wide application prospect. Laponite-based nanocomposites are currently a hot research direction in the biomedical field. Self-assembly, porosity, good biocompatibility and physical properties provide a good guarantee for Laponite nano-biological scaffolds. More basic studies are needed to clarify its mechanism. Combining basic research with clinical application will help Laponite materials to be used safely in clinical practice.
