Abstract
A one-step method for fabricating solidified particles from all-aqueous emulsion droplets involves solidification and drying of the droplets by osmosis. According to this method the fabrication of solidified particles is induced by implementing a high osmotic pressure gradient between the internal phase and external phase of the all-aqueous emulsion. The resultant extraction of water leads to solidification of the emulsion droplets. This approach provides mild conditions for encapsulating bioactive ingredients or other delicate components to conveniently fabricate bio- and cyto-compatible particles because it does not involve the introduction of external energy used in conventional drying. Such conventional external energy inputs are time-consuming, so the method is more efficient.
