Comparison of methods for microgel fabrication.

Method	Advantages	Disadvantages
Micromolding	Controlled shape and size. Easy fabrication.	Batch process. Masks production. Uneven surface.
Photolithography	Controlled shape and size.	Batch process. Cell toxic photoinitiator. Cost for photolithograph masks.
Microfluidic	Homogeneous, continuous.	Non scalable. Microfluidic fabrication. Limited geometry due to pressure drop, PDMS affinity for small hydrophobic molecules.
Emulsification	Easily scalable.	Limited to spherical shapes.
