Research interests

Current projects focus on the following basic and applied research activities:

Thrombogenicity of blood contacting medical devices

• Microfluidic flow-based platforms, able to stimulate platelets with abnormal shear-stress patterns typical of blood medical devices (mechanical heart valves, ventricular assist devices and blood oxygenators)
• Microfluidic flow-based platforms for testing the efficacy of antiplatelet drugs under hyper-shear conditions
• Device Thrombogenicity Emulator (DTE): combining advanced computational and experimental techniques for optimizing the thrombogenic performance of cardiovascular devices
• Evaluation of the thrombogenicity of material surfaces of blood-contacting devices

Platelet function testing

• Point-of-care platelet aggregation systems, integrating microfluidics, electronics and impedance measurements
• Shear-mediated thrombus formation on collagen-coated microchannels, mimicking physiologic and stenotic arteries

In vitro thrombogenicity testing

• Platelet activity state (PAS) assay, allowing the measurement of the real-time thrombin production rate of activated platelets
• Hemodynamic Shearing Device (HSD) a state-of-the-art benchtop system designed to expose platelets to defined levels and patterns of shear-stress

Platelet-on-chip technologies

• Lab-on-a chip systems for continuous platelet separation from whole blood
• On-chip platelet cell counter for rapid and automated measurement of platelet concentration
