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.
