Responsive Nanocellulose-Pnipam Millicapsules

Journal of Colloid and Interface Science
Milli- and micro-capsules are developed to facilitate the controlled release of diverse active ingredients by passive diffusion or a triggered burst. As applications expand, capsules are required to be increasingly multi-functional, combining benefits like encapsulation, response, release, and even movement.
