摘要
Converting colloidal systems, such as emulsions, dispersions, and suspensions to powders is highly demanded in a myriad of biomedical, pharmaceutical, cosmetic, oil and gas, food, energy, and environmental applications. Handling colloids is typically associated with persistent challenges including bacterial and viral contaminations, lack of terminal sterilization, impaired stability, short shelf life, high processing costs, and difficult packaging and transportation. Current techniques such as freeze-drying and spray-drying have noticeably failed in completely preserving the properties of dispersed phase while removing the continuous phase. The invention disclosed herein provides a new and easy method to convert colloidal systems to powders that are able to readily revive their properties upon resuspension.
