“…Addressing these limitations, our research introduces a passive device designed to match the processing capabilities of nitrocellulose-based systems while enabling cell analysis, offering a simpler, cost-effective solution for comprehensive blood diagnostics. Research has been conducted on improving the capillary action in biocompatible polymer microfluidic systems [ 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 ]. Certain systems have been maximized in terms of the pumping efficiency without using nitrocellulose capillary pump structures [ 23 , 32 ].…”
