Now we fix nitrogen!

The “bionic leaf” device that Chong was developing in Prof. Dan Nocera’s lab at Harvard extends the range of molecules that it can handle. Beyond the efficient CO2-fixing device that was reported last year in Science, now we applied a diazotrophic bacterium to fix N2 and demonstrated the use of bio-fertilizer generated by electricity. This work is published online in PNAS this week, of which Chong and Kelsey are co-first authors.
