My feature on Spherical Nucleic Acids (SNAs) - a kind of assembly in which short nucleic acid strands stick out radially from a nanoparticle core - is out in the September issue of Chemistry & Industry:
DNA plays ball
Chemistry & Industry 2013, No. 9, pp28-31
This is premium content with restricted access to the full text, but I may get pdf reprints.

PS - as punishment for making fun of people for publishing DNA helices the wrong way round, I've been hit by another inverted helix in the illustrations for this article, which I didn't get to check. Fortunately, it's a detailed ball-and sticks model where the chirality is very hard to verify, so it won't mislead anybody who doesn't know already which way the helix is supposed to turn.
