Nanodevices Self-Assemble Using DNA
8/1/2012

Single-stranded tiles (SSTs) made of short strands of interlocking DNA can be programmed to assemble themselves into precisely designed shapes, including letters, numbers, and emoticons.   (Source: Wyss Institute at Harvard University)

Scientists are doing the same thing with MEMS-based devices, which self-assemble using an origami aspect of 'unfolding' themselves.

Thanks williamlweaver, glad you liked the article. Self-assembled devices is becoming quite an an active area of research. I have read Crichton's PREY: pretty scary stuff, in fact I found it his scariest so far because it's so believable, perhaps even inevitable. Thanks for the link to your swarms article--another area of research that's getting a lot of play, especially in robotics.

Isn't this amazing? Targeted drug delivery is definitely one of the possible apps the researchers have in mind, and if that could be done for chemotherapy it would make a lot of people healthier and happier.

This is fantastic stuff, Ann. For those who wish to learn more about the application of this technology, you can read it here:
 
 
Just like Jurassic Park introduced the public to genomic technology, PREY explores the development of nanobots and genetic assembly. Let's hope that reality has a happier ending...
 
If you are interested, I wrote about this topic in April 2004. It looks like we are almost there.

This is fascinating new technology, Ann. I would imagine one of the applications could be targeting chemotherapy to the cancer instead of having to broadcast it to healthy cells as well as cancerous cells.
