摘要
En 中文
微流控技术因其高通量、所需样品量少和快速传质等优点,有望作为下一代医疗检测技术取代传统医疗检测方法。然而,微流控芯片大多需要蠕动泵提供压力以输送样品,这限制了其即时检测能力和便携性。本文开发了一种适用于刚性及柔性基底的、基于重力驱动的液滴式微流控多通道拉曼传感器。此外,还提出了其制备方法。所开发的基于重力驱动的多通道拉曼传感器易于制造、厚度薄、成本低,且无需外部能量输入。通过使用孔雀石绿对所开发传感器的性能进行表征,在633 nm激光照射下,可检测最低10⁻⁸ mol/L的孔雀石绿。此外,我们还优化了其尺寸,同时保留了易于制造、经济性和薄型等优良特性。所提出的传感器为便携式芯片上液滴检测提供了一种新的视角。
