Release of encapsulated content in microdroplets.
نویسندگان
چکیده
A method for releasing the content of microdroplets by changing the channel wall wettability is proposed. The contents of aqueous droplets were released to the continuous phase by inverting 10-µm-sized W/O droplets into O/W ones in a 2-µm-deep hydrophilic channel. The combination of "encapsulation" and "release" in microdroplets facilitates micromixing and reaction.

Microfluidic Encapsulation of Pickering Oil Microdroplets into Alginate Microgels for Lipophilic Compound Delivery
Alginate microgels are widely used as delivery systems in food, cosmetics, and pharmaceutical industries for encapsulation and sustained release of hydrophilic compounds and cells. However, the encapsulation of lipophilic molecules inside these microgels remains a great challenge because of the complex oil-core matrix required. The present study describes an original two-step approach allowing ...
