Gold nanotubes for theranostic applications

Researchers have exploited gold nanotubes with controlled length and tunable absorption in the near-infrared (NIR) region for applications as photothermal conversion agents and in vivo photoacoustic imaging contrast agents. They developed a length-controlled synthesis to fabricate gold nanotubes with well-defined shape, high crystallinity, and tunable NIR surface plasmon resonance.

How to make silver nanowires almost indestructible

Researchers found that silver nanowires can be made almost indestructible and highly bendable by covering the minuscule wire with silicon dioxide. The new material can be used for making next generation optical cables, which until now have been easily fractured if bent. The new material 'memorizes' its original position and regenerates when needed.

Novel crumpling method takes flat graphene from 2-D to 3-D

Researchers have developed a unique single-step process to achieve three-dimensional (3D) texturing of graphene and graphite. Using a commercially available thermally activated shape-memory polymer substrate, this 3D texturing, or 'crumpling', allows for increased surface area and opens the doors to expanded capabilities for electronics and biomaterials.
