To achieve high resolution and tunable separation cutoff diameters for complex samples.
To overcome the limitations of bimodal separation in conventional inertial microfluidic devices.

Main Methods:

Design of a novel microfluidic channel system leveraging inertial focusing principles.
Implementation of hydrodynamic forces for precise manipulation and migration of microparticles.
Demonstration of continuous separation of microparticles with adjustable size cutoffs.

Main Results:

Achieved continuous multimodal microparticle sorting with high resolution.
Demonstrated flexible modulation of separation bandwidth and passband location.
Showcased easily tunable and precisely controlled separation cutoff diameters.
Maintained high throughput comparable to existing methods.

Conclusions:

The developed microfluidic device enables advanced multimodal sorting of complex microparticle samples.
This approach significantly expands the applicability of inertial microfluidics.
The system offers straightforward design, precise tunability, and high-performance separation.
