In-Depth Information
this relatively young research area. The first is still the need of more materials
that can be developed into suitable building blocks for DNA-programmable self-
assembly. This is especially important from a material science's viewpoint. Besides
optical properties, there are very few reports dealing with other physical/chemical
properties (through much richer) of DNA-directed nanomaterials. Also, hybrid
nanostructures built between different materials need a further exploration for the
special roles of the heterogeneous interface in their functional implementations.
The compatibility problem and mutual interactions between different materials
still remain largely unexplored, which will be critical for the functioning of a
multicomponent self-assembly system. Finally, more practical applications of self-
assembled nanomaterials are still not seen, but should become closer to us with
continued pursuits. We believe these challenges provide a vast diversity of research
topics that will attract scientists with a broad range of background to join in this
fascinating research area. The development of DNA-directed nanomaterials science
into the next phase can therefore be expected in the near future.
