Study of hollow colloidosomes using polyhydroxybutyrate (PHB) as polymer via two steps solvent evaporation method

Colloidosomes is a hollow and composed of a closely-dense packed layer of colloidal particles whose permeability and elasticity can be tuned and highly controllable. Hollow colloidosomes offer a great potential in wide areas such as controlling the release rate of entrapped materials, cosmetics, foo...
