本研究报告了一种用于全血处理的微流控装置。该装置使用分叉定律、交叉流方法和流体动力学流,用于同时提取血浆、红细胞和片上白色血细胞捕获。结果表明,成功采集了血浆和红细胞,最小稀释因子(0.76 x)和低溶血效应。提取的红细胞也可用于血型检测。此外,该装置可以在20分钟内捕获多达1,800个白色血细胞。仅需6 μL全血即可同时采集三种组分,无需任何样品制备过程。基于这些特征,微流体装置实现了低成本、快速和有效的全血处理功能,其可以潜在地应用于资源有限的环境或护理点环境中的血液分析。
This study reports a microfluidic device for whole blood processing. The device uses the bifurcation law, cross-flow method, and hydrodynamic flow for simultaneous extraction of plasma, red blood cells, and on-chip white blood cell trapping. The results demonstrate successful plasma and red blood cell collection with a minimum dilution factor (0.76x) and low haemolysis effect. The extracted red blood cells can also be applied for blood type tests. Moreover, the device can trap up to ~1,800 white blood cells in 20 minutes. The three components can be collected simultaneously using only 6 μL of whole blood without any sample preparation processes. Based on these features, the microfluidic device enables low-cost, rapid, and efficient whole blood processing functionality that could potentially be applied for blood analysis in resource-limited environments or point-of-care settings.
