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.

Aptamers and their applications in nanomedicine

To construct ligand-directed 'active targeting' nanobased delivery systems, aptamer-equipped nanomedicines have been tested for in vitro diagnosis, in vivo imaging, targeted cancer therapy, theranostic approaches, sub-cellular molecule detection, food safety, and environmental monitoring.
