What would you like to "build with biology"? The goal of the GeneFab project is to develop technology for the rapid fabrication of large DNA molecules, with composition specified directly by the user. Our intent is to facilitate the field of synthetic biology as it moves from a focus on single genes to designing complete biochemical pathways, genetic networks, and more complex systems. Sub-projects include: DNA error correction, microfluidics for high throughput gene synthesis, and genome-scale engineering (rE. coli).
