Image credit: WikipediaIn the previous post, I introduced DNA nanotechnology and talked a bit about some of the 2-D structures that researchers have devised. Scientists have also used these techniques to build a variety of 3-D shapes, some of which can be used as containers for drug delivery. In this post, I’m going to focus on the DNA tetrahedron, a four-sided pyramid made of DNA which is relatively easy to build and manipulate and has proven useful in several recent studies.

Image credit: WikipediaThe phrase “DNA nanotechnology” has a thoroughly futuristic ring. It sounds like something from a science-fiction novel, but what does it actually mean? Nanotechnology just means manipulating stuff on the scale of atoms and molecules. DNA nanotechnology is an approach that harnesses the self-organizing properties of DNA. The idea is to use DNA to precisely position things or build structures and machines, ideally in a way that’s cheaper or more efficient than other techniques.
