composed of monolayers of liquid-like, close-packed nanoparticles. The gelation of aqueous phase with agarose leads to robust and water-dispersible nanoparticle colloidosomes, allowing encapsulation of various water soluble materials. The cutoff of the nanoparticle colloidosomes
obtained is primarily defined by the nanoparticle size. This controllable permeability should be of great importance for the encapsulation
application.
