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.

Harvard SEAS researchers have created a device that can bridge digital electronic signals and analog light signals in one fluid step, offering a potential replacement for energy-intensive systems used in today’s high-speed data networks. The researchers’ device was fabricated using a lithium niobate foundry process developed by HyperLight Corporation, a startup that is advancing innovations from Prof. Marko Loncar’s lab.
