Abstract:

BACKGROUND: Single cell nanoencapsulation refers to coating single cells with ultrathin (< 100 nm) layers and it has been widely used in medical and biological areas.

OBJECTIVE: To review the development and applications of single cell nanoencapsulation.
METHODS: The literature search was performed in PubMed, CNKI and WanFang database, and the keywords were “single cell, nano-coating, nano-encapsulation, cell-in-shell structure” in English and Chinese, respectively. According to the inclusion and exclusion criteria, 52 articles were finally reviewed.

RESULTS AND CONCLUSION: The layer-by-layer deposition technique is most widely used due to their versatile processing and tunable properties. And many other materials, like polyphenols and surface-induced hydrogelator have been also utilized as organic cell-coating materials. Besides, bioinspired mineralization and crystallization were utilized for creating inorganic nanoshells. Single cell nanoencapsulation has been widely used in many important areas, including cell biocatalysis, cell therapy, cytoprotection and cell-based biology. Extensive adhesion of polyphenols and self-assembling of some organic materials have been also utilized to form nanoencapsulation of single cells. Besides, bioinspired mineralization and crystallization have been utilized for creating inorganic nanoshells. Nanoencapsulated single cells have been widely used in many important areas, including cell biocatalysis, cell therapy, cytoprotection and cell-based biology. The application of encapsulated cells will make a more important part in the selection of nanocoating materials in future research.
