DNA tiles provide faster, less expensive way to fabricate complex DNA objects
Researchers at the Wyss Institute for Biologically Inspired Engineering at Harvard University 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.
DNA tiles provide faster, less expensive way to fabricate complex DNA objects
A set of 310 short single-stranded DNA tiles, plus a few additional short sequences for the edges, has been used to form more than a hundred large, complex DNA objects.
