Setup

Checklist: Setting Up a GUV Production System

Obtain Necessary Equipment:
- OB1 flow controller
- Double emulsions chip (e.g., microfluidic ChipShop fluidic 1032)
Prepare the Fluid Channels:
- Inner aqueous solution (1st channel)
- Oil/lipid-based solution (2nd channel)
- Outer aqueous solution (3rd channel)
Assemble the Microfluidic Setup:
- Connect the OB1 flow controller to the three fluid channels.
- Ensure the channels converge at the junctions of the double emulsions chip.
Test and Optimize:
- Verify precise control over fluid flow using the OB1 controller.
- Adjust as needed for GUV production.
Adapt for Other Applications:
- Modify the setup for other double emulsion application processes if required.

Applications

GUVs can be used for various applications such as:

Membrane-protein interaction assays
Drug delivery studies
Artificial cell-like systems
Encapsulation assays
Membrane deformation studies
and much more!
