I am interested in DNA-based nanoscience research.  What kind of background is needed to succeed in this field?



My background is in crystallography.  A good sense of 3D structure is important, in my opinion.  However, one cannot be too deficient in math, chemistry, physics or computer science.  I find that exposure to art helps in the generation o....more


I am interested in carbon nanotubes and how it relates to DNA.  Do you have any insights on how these two nanoscience building blocks can be used together?



Carbon nanotubes and DNA are about the same size.  There are many experiments in which DNA has been wrapped around carbon nanotubes.  An early reference is Chou et al.,1 which has been cited 56 times.  It seems that t....more


There has been a lot of recent growth in the field of structural DNA nanotechnology.  What are some of the practical applications for this technology?



Organization of mater on the nanoscale. DNA is a robust molecule and it is capable of organizing other chemical species, such as proteins or nanolectronic components.  There have been recent examples of organizing metallic nanoparticles, and....more
