The directed metallization of DNA origami nanostructures
could give
rise to self-assembling materials with novel optical and
electronic
properties. We show that three-dimensional (3D) DNA origami
structures
can be converted into gold nanoparticles of designed shapes
by a two-
step metallization process: Positively charged 1.4 nm gold
nanoclusters adsorb to the negatively charged...

Self-assembly is a fundamental process in the
self-organization of biological as well as non-biological
structures. Passive self-assembly of molecular units, being
driven just by thermodynamic binding energies and the
geometrical structure of the molecules, would seem to be the
simplest case to study -- but it can be remarkably
complicated. In fact, in a model of generalized...

The highly predictable interactions between DNA or RNA
molecules have been utilized for the construction of a large
variety of molecular structures and devices. For instance,
the recently developed DNA origami technique facilitates the
molecular assembly of two- and even three-dimensional
nano-objects with almost arbitrary shape - and with
nanometric precision. These structures can be...
