SSI Biology will use an EWOD-based system in their [[DNA Synthesizer]]. The growing DNA strands will be immobilized on magnetic beads in a droplet on one electrode. Droplets containing DNA synthesis reagents like [[Terminal Deoxynucleotidyl Transferase]] can be merged with the droplet containing the DNA to start reactions. When a given reaction step is complete, the droplet can then be moved off the electrode containing the DNA to a waste chamber, without the magnetic bead-bound DNA being washed away. After the desired DNA sequence is synthesized, it can be cleaved off the beads and moved to a desired location for downstream applications. | SSI Biology will use an EWOD-based system in their [[DNA Synthesizer]].
