In history, it was first Bi Sheng and then Gutenberg who used movable type blocks to revolutionize printing. Computer microchips are “printed” on silicon disks using a photo-etching and plating process to create miniature circuitry patterns. More than a few research teams have been chasing the best way to accomplish nanoprinting and using a wide variety of techniques. A new process that uses electrically charged DNA molecules shows promise for developing a “printing plate” that can be reused multiple times.

When Gutenberg developed the principles of modern book printing, books became available to the masses. Hoping to bring technology capable of mass production to the nanometer scale, Udo Bach and this team of scientists at Monash University (Australia) and the Lawrence Berkeley National Laboratory (USA) have developed a nanoprinting process modeled on Gutenberg’s printing method. Their goal is the simple, inexpensive production of nanotechnological components for solar cells, biosensors, and other electronic systems.

Northwestern University researchers have developed a new technique for rapidly prototyping nanoscale devices and structures that is so inexpensive the “print head” can be thrown away when done.
Hard-tip, soft-spring lithography (HSL) rolls into one method the best of scanning-probe lithography — high resolution — and the best of polymer pen lithography — low cost and easy implementation.
HSL could be used in the areas of electronics (electronic circuits), medical diagnostics (gene chips and arrays of biomolecules) and pharmaceuticals (arrays for screening drug candidates), among others.
