ABSTRACT

Nano-dumbbells via electrospinning: controllable nano-dumbbells are fabricated via electrospinning. The weight block parts and the length of nanowires between them can be adjusted through changing the experimental conditions. This nanostructure enables ultralow-limit gas sensing properties of the resulting polypyrrole-based microsensor.
