Optofluidics is a new field of modern science that stands at the interface of microfluidics and photonics and has good prospects for application in gas sensors. Microfluidics offers a promising platform for tuning and assembling monolayer structures that are used as sensitive layers for gas detection. Herein, we evaluate the concept of monolayer formation on a silicon nitride substrate enabling a surface coverage up to 59% through a microfluidic convective assembly and couple it with a photonic integrated chip to probe gas sensing performance.

用于气体传感应用的基于光子集成芯片的微流体系统内二氧化硅胶体颗粒的对流组装

光流控是现代科学的一个新领域，处于微流控和光子学的交叉领域，在气体传感器方面具有良好的应用前景。微流控技术为调整和组装单层结构提供了一个有前景的平台，这些单层结构用作气体检测的敏感层。在此，我们评估了在氮化硅基底上形成单层的概念，通过微流体对流组件实现高达 59% 的表面覆盖率，并将其与光子集成芯片耦合以探测气体传感性能。
