Making DNA on a Semiconductor Chip
A Harvard-led team synthesized 64 distinct DNA sequences on a silicon chip in parallel – not by using the solvent-heavy chemistry that dominates custom DNA manufacturing today, but through a water-based enzymatic process. The research was led by Donhee Ham, the John A. and Elizabeth S. Armstrong Professor of Engineering and Applied Sciences at the John A. Paulson School of Engineering and Applied Sciences.
