| abstract |
The present invention relates to a Pickering emulsion comprising an aqueous phase, an oil phase and a nanoparticle, wherein the nanoparticle is a protein cage. The protein cage is preferably a Bacillus stearothermophilus E2 protein of pyruvate dehydrogenase multi-enzyme complex or an E2LC2 protein. Preferably the aqueous or oil phase of the Pickering emulsion com prises an agent, or the protein cage is coupled to or loaded with an agent, wherein the agent is a therapeutic, nutritional, nutraceutical or cosmetic agent. The invention further includes use of the Pickering emulsions disclosed herein in pharmaceutical, cosmetic, or food applications, or as a controlled release delivery system, and use of protein cages as emulsifiers in Pickering emulsions. |
