Review Stresses Biomedical Applications for Designed DNA Nanostructures

The folded structures have high spatial addressability and tremendous potential to serve as platforms and active components in a plethora of bio-nanotechnological applications. They stressed that DNA is a truly programmable material, and its nanoscale engineering opens up numerous attractive possibilities to develop novel methods for therapeutics. Furthermore, tailored molecular devices could be used to target cells and trigger cellular actions in the biological environment.

"Nowadays, software and techniques to design and simulate DNA nanostructures are extremely powerful and user-friendly, and thus, researchers can easily construct their own DNA-objects for various uses. The big boom in the field of structural DNA nanotechnology happened in 2006, when Paul Rothemund introduced a technique dubbed "DNA origami". This method is the starting point for practically all other straightforward design approaches available today", said first author Dr. Veikko Linko, a postdoctoral researcher in biohybrid materials at Aalto University.
