It turns out DNA isn't limited to being the mere building blocks of life. The proteins which comprise DNA can also be used as component materials within nanotechnology. Which is exactly what the Wyss Institute have demonstrated, by creating an entire font from DNA particles, each character 100 nanometers (billionths of a meter) in size...

Making Structures with DNA "Building Blocks" from Wyss Institute on Vimeo.

Researchers at the Wyss Institute have developed a method for building complex nanostructures out of short synthetic strands of DNA. Called single-stranded tiles (SSTs), these interlocking DNA "building blocks," akin to Legos®, can be programmed to assemble themselves into precisely designed shapes, such as letters and emoticons. Further development of the technology could enable the creation of new nanoscale devices, such as those that deliver drugs directly to disease sites.
