Osmotic Drying of All-Aqueous Emulsions

Summary

The present invention relates generally to a method for fabricating solidified particles or micro-particles based on an all-aqueous emulsion system containing two or more different immiscible aqueous phases with a high osmotic pressure gradient between them. MOre specifically, the method relies on osmosis-induced water extraction from the internal phase to the external phase by increasing the concentration of osmolytes in the external phase. This method can be applied to the fabrication of biocompatible solidified particles.

Technology Benefits

- A new process to dry all aqueous emulsion droplets to form solid micro-particles, which water in the internal phase is extracted by osmotic pressure
- Aqueous solutions are recyclable and the setup is simple.
