DNA origami on the rise

Nanotechnology is all the rage these days but its use by practicing biologists is still very limited. A recent entry in the nanotechnology arena is DNA origami, a method for creating nanostructures out of DNA that is more accessible than previous methods and allows larger and more complex structures to be created with greater ease.

In the April issue of Nature Methods you will find a primer to DNA origami that provides an excellent introduction to this technology with valuable practical advice on designing and synthesizing DNA nanostructures using the DNA origami methodology. We hope that this primer will stimulate biologists or others new to this field to take a look at this technology and dream up exciting new applications.

One of the crucial steps of DNA origami is isolating your properly folded structure. A Correspondence by William Shih, one of the pioneers of DNA origami, describes some simple but very useful modifications to an agarose gel electroelution method that many people use for isolating PCR products or small DNA fragments from restriction digests. These changes greatly increase the efficiency of isolating intact large DNA nanostructures compared to existing methods.

Finally, the Editorial discusses the prospects of DNA nanostructures created using DNA origami as biological research tools.

Based on the number of posters describing applications of DNA origami at the 2010 Gordon Research Conference on Single Molecule Approaches to Cell Biology, compared to previous years the biological community and the single molecule biophysics community in particular is showing interest in the methodology. Only time will tell if it fairs better among biologists than other promising nanotechnology tools and methods.

We’d like to know what our readers think of the biological research prospects of this technology, or other nanotechnology tools and methods for that matter. Tell us what you think.

Research collaboration

The Editorial in the February issue of Nature Methods discusses the critical role that interdisciplinary collaboration plays in modern biomedical research. Although there are certainly notable exceptions, researchers seem to be increasingly using collaborations with experts outside their own area of expertise to bring new insights and technologies to their research projects. Increasing numbers of studies claim to back up the assumption that collaboration is beneficial.

As highlighted in a 2008 News Feature in Nature, collaborations can also go horribly wrong and an accompanying editorial urged researchers to take some basic steps to avoid unforeseen complications.

At Nature Methods we were curious if the methods papers we had published showed any evidence of benefits arising from interdisciplinary collaboration. We calculated the number of citations per year that each of our research papers published between 2004 and May 2010 had received and analyzed the author patterns of those in the top and bottom quartiles. As briefly described in the February Editorial we detected what seemed to be a positive effect of interdisciplinary collaborations on the apparent impact of the work. This was by no means a rigorous study and there are many caveats, but it certainly suggests that even in methods development, collaboration is beneficial.

Do you have anything to share about your experiences with collaboration? We’d love to hear them.
