表面增强拉曼光谱（Sers）活性材料的芯片上制造使得能够在微流体芯片中连续、实时地感测目标。然而，目前的技术需要耗时，复杂的过程和昂贵的，庞大的设备。在这项工作中，我们提出了一种新的方法来合成银纳米结构的微流控通道通过一步无电镀置换反应。整个反应可以实现
On-chip fabrication of surface-enhanced Raman spectroscopy (SERS)-active materials enables continuous, real-time sensing of targets in the microfluidic chip. However, the current techniques require the time-consuming, complicated process and costly, bulky facilities. In this work, we present a novel method for synthesis of Ag nano-structures in a microfluidic channel via one-step electroless galvanic replacement reaction. The whole reaction could be achieved
