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.
