提出了一种具有可控尺寸和局域表面等离子体共振(LSPR)波长的银纳米粒子的合成方法。在一个微芯片中，可以产生高度单分散性和稳定性的液滴。以液滴为微反应器，采用晶种介导法成功地制备了银纳米粒子。实验结果表明，通过调整液滴加热温度、反应时间、银粒子和硝酸银在水相中的浓度等合成条件，可以优化纳米粒子的尺寸和LSPR波长。这些结果表明，所提出的微器件可以为制备性能最佳的纳米粒子提供一种方便且廉价的方法。
A method was developed to synthesize silver nanoparticles with controlled size and Localized Surface Plasmon Resonance (LSPR) wavelength. In a microchip, droplets with high monodispersity and stability were produced. Using droplets as microreactors, seed-mediated growth approach was successfully applied for silver nanoparticles preparation. It was observed that nanoparticles size and LSPR wavelength could be optimized via adjusting synthesis conditions, such as droplets heating temperature, reaction time, and concentration of silver seeds and silver nitrate in aqueous phase. These results indicated that the proposed microdevices could provide a convenient and inexpensive approach for preparing nanoparticles with optimum properties.
