This approach offers a simpler, lower-cost alternative to traditional microfluidic methods that rely on external forces. Its ability to focus, concentrate, and separate particles makes it highly valuable for complex biological and industrial sample processing.
What This Means for Your Design
Imagine tiny channels where the way the fluid flows, not just its stickiness, can push particles around. This lets us sort and gather tiny things very quickly and cheaply.
