Dataset description

This dataset is associated with one article which presents a simple and highly reliable method for preparing PDMS microfluidic double emulsion devices that employs a single-step oxidative plasma treatment to both pattern the wettability of microchannels and to bond the chips. As a key component of our strategy we use epoxy glue to define the required hydrophobic zones and then remove this after plasma treatment, but prior to bonding. This novel approach achieves surface modification and device sealing in a single process, which reduces chip preparation times to minutes and eliminates the need for unreliable coating processes. The second key element of our procedure is the maintenance of the patterned surfaces, where we demonstrate that immediate filling of the prepared device with water or the use of solvent-extracted PDMS vastly extends the operational lifetimes of the chips. This is a very useful technique to prepare microfluidic device with alternative surface wettabilities.
