Adaptive subwavelength control of nano-optical fields
Article Abstract:
The mapping of photoemission patterns governed by local optical near fields with nanometer resolution is demonstrated and it is shown that optical near fields can be manipulated on a subdiffraction length scale. The combination of adaptive control and nano-optics has achieved subwavelength dynamic localization of electromagnetic intensity on the nanometre scale and thus overcome the spatial restrictions of conventional optics.

Folding DNA to create nanoscale shapes and patterns
Article Abstract:
A simple method for folding long, single-stranded DNA molecules into arbitrary two-dimensional shapes is described. Once synthesized and mixed, the staple and scaffold strands self-assemble in a single step and the resulting DNA structures are roughly 100 nm in diameter with approximate desired shapes such as squares, disks and five-pointed stars with a spatial resolution of 6 nm.

Porous solids get organized
Article Abstract:
A novel combination of spectroscopic tools is being used to study the mechanistic details of the synthesis of complex nanoporous solids. The results indicate that molecular complexes in the synthetic mixture recognize template molecules, so forming clusters from which ordered structures may grow.
