摘要
Highly uniform SnO2 nanowires, with bulk electronic properties directed by their surface chemistry, have been produced by isolating and oxidizing tin nanowires selected from a template-synthesized array. The nanowires act as sensitive, fast, stable, and reproducible gas sensors that can be easily integrated into a multi-component array (see Figure).
