摘要

首次采用激光诱导反向转移技术在微流体系统中沉积银纳米颗粒。在熔融二氧化硅表面的预制储层作为受体，而体银靶（供体）用纳秒激光脉冲烧蚀。所制备的微流控系统通过与鲁米诺的化学发光反应来检测活性氧。我们发现，与没有银纳米颗粒的微流控系统相比，LIBT沉积的银纳米颗粒增强了鲁米诺化学发光高达66%。确定了光催化沉积纳米银的最佳工艺条件。

A novel method for silver nanoparticle deposition in microfluidic systems: backward laser transfer approach

Laser-induced backward transfer (LIBT) was for the first time employed to deposit silver nanoparticles in a microfluidic system. The prefabricated reservoir on a fused silica surface served as an acceptor while the bulk silver target (donor) was ablated with nanosecond laser pulses. The obtained microfluidic system was used for the detection of reactive oxygen species via chemiluminescent reaction with luminol. We found that LIBT deposited silver nanoparticles enhance luminol chemiluminescence by up to 66% compared to the reference in a microfluidic system without silver nanoparticles. The optimum conditions were established for the deposition of silver nanoparticles by LIBT.
