Figure S2: PEG-DA microbeads observed in hexadecane (10X) in dark field. The size was measured to be 62.8 +3 µm (Scale Bar = 100 µm).

Figure S3: SEM images of PEG-DA microbeads observed after drying. A typical fold morphology of structures is caused due to dehydration and heating of the capsules during SEM procedures. The white crystal (right) indicate salt crystals from 1X PBS.
