Researchers Write Protein Nanoarrays Using a Fountain Pen and Electric Fields
October 15, 2008
Most tools capable of patterning on the nanoscale were developed for the silicon microelectronics industry and cannot be used for soft and relatively sensitive biomaterials, such as DNA and proteins. Now, Northwestern University researchers have demonstrated the ability to rapidly write nanoscale protein arrays using a tool they call the nanofountain probe. The probe works much like a fountain pen, only on a much smaller scale, and the "ink" is the protein solution.
The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2016, its budget is $7.5 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives more than 48,000 competitive proposals for funding and makes about 12,000 new funding awards. NSF also awards about $626 million in professional and service contracts yearly.
