摘要
It is provided a microspherical structure comprising an external shell of structured cellulose nanocrystals (CNCs) and at least one polymer, and a core, wherein the core can be hollow or filled with an immiscible medium. It is also provided a method for producing the same comprising spray-drying the mixture of CNCs and polymer through an atomizer and into a drying chamber forming droplets, wherein the solvent used to suspend the CNCs is evaporated and the microspherical structures are formed. These microstructural spheres can have wide industrial, medical and pharmaceutical applications, whereby their ingredients and structure are tuned and controlled.
