Implication

May enable efficient preclinical platelet testing with minimal volumes; leaves open human validation before any clinical use.

Key Points

To develop and evaluate a well-plate microfluidic system capable of conducting multiplexed, shear-based thrombosis assays using minimal blood volumes.
Fabricated a well-plate microfluidic platform to measure platelet adhesion and thrombus formation under controlled shear flow across collagen I and von Willebrand factor substrates.
Conducted real-time dose-response assays of the antiplatelet agent abciximab using single donor blood samples.
Configured the platform to evaluate up to 24 experimental conditions simultaneously while maintaining identical physical shear conditions across channels.
The microfluidic device enabled simultaneous, real-time visualization of platelet adhesion and thrombus accumulation across matrix proteins under physiological and pathological shear stress.
The system yielded full dose-response curves for abciximab from a single patient blood volume, substantially reducing sample volume requirements compared to cone-and-plate or parallel-plate systems.
