| Outline of Final Research Achievements |
Nanocellulose, a natural colloidal nanofibril, is a promising candidate material for applications in such structures, owing to its unique nanoscale dimension, excellent mechanical properties, and good chemical stability. However, processes for assembling this material into structures at the nanoscale have yet to be explored. Here, we develop a robust approach to forming ultrathin shells of nanocellulose on polymer microparticles through emulsion-templated assembly. The particles showed good dispersibility in water and mechanical resistance. The surface nanocellulose shells showed pH-sensitive drug loading/releasing properties, which suggest potential for a range of therapeutic and biomedical applications.
