i)We demonstrate the facile, rational synthesis of monodispersedly sized ZnO nanowires from randomly sized seeds by hydrothermal growth. Byprecisely controlling the sharp tip formation and the nucleation, our method substantially narrows the distribution of ZnO nanowire diametersfrom σ = 13.5 nm down to σ = 1.3 nm and controls their diameter , even initiating from randomly sized seeds.ii)We artificially synthesis of molecular recognition nanowire surface via ALD technique The ZnO/TiO2 nanowires fabricated with nonanal templateexhibited much higher molecule collection ability compared with the ones without template. Furthermore, we found that the ZnO/TiO2 nanowires with templatenonanal shows selectively to target nonanal among mixed linear aldehyde molecules。

i）我们通过热液生长证明了来自随机大小的种子的单分散大小的ZnO纳米线的简便，合理的合成。我们的方法副本控制了尖尖的形成和成核，我们的方法实质上将Zno纳米线直径的分布从σ= 13.5 nm到σ= 1.3 = 1.3 nm，甚至从随机尺寸开始，甚至从随机尺寸的种子开始，我们通过ZNON的nanon noan noan non non notiqual notific notial n ano notique notific notiqual notific notiqual notife与没有模板的分子收集能力相比，Template Exhhib比分子收集能力更高。此外，我们发现，具有静脉曲素的ZnO/TiO2纳米线选择性地显示了混合线性醛分子之间靶向nonanal。
