通过在可见光/近红外区域的光谱分析，我们展示了一个单一的波导聚苯胺/聚苯乙烯纳米线的高选择性检测的气体混合物与NH（3）的检测限百万分之几的水平和相对湿度传感范围从37%到84%。这里所示的紧凑和灵活的传感方案可能是有吸引力的高选择性的光学检测在复杂的化学或生物环境中与一个单一的纳米线。
By using spectral analysis in the visible/near-infrared region, we demonstrate a single waveguiding polyaniline/polystyrene nanowire for highly selective detection of gas mixtures with a NH(3) detection limit on parts-per-million level and relative humidity sensing ranging from 37% to 84%. The compact and flexible sensing scheme shown here may be attractive for highly selective optical detection in complex chemical or biological environments with a single nanowire.
