Implementation Considerations

• Requires expertise in microfluidic device handling, high-speed imaging, and image processing techniques for binary thresholding and particle labeling.
• Depends on microfluidic fabrication capabilities, high-speed cameras capable of ≥18 fps, and μPIV systems for velocity field determination.
• Necessitates cross-team standardization of hematocrit preparation, tracer particle concentration, and flow rate protocols to ensure comparability across experiments.
• Involves adaptation considerations when extending to diseased RBC samples or varying plasma conditions that may alter aggregation kinetics.
• Includes practical limitations such as the need for bubble-free systems, steady-state flow validation, and manual validation of blood layer thickness for shear rate calculation.
