Vorticity‐Facilitated Platelet Aggregation: a High Expansion‐Ratio Stenotic Microfluidic Platform Unravels the Role of Complex Flow Dynamics in Arterial Thrombosis

open access: yesAdvanced Healthcare Materials, EarlyView.
This study reveals how vorticity—a swirling flow pattern—enhances platelet aggregation and thrombus formation in high‐shear conditions. Using a custom microfluidic model, it is shows that vorticity promotes vWF–GPIbα interactions and calcium signaling, providing new insights into thrombosis mechanobiology and informing safer blood‐contacting medical ...

Effect of Nanoparticle Rigidity on the Interaction of Stromal Membrane Particles with Leukemia Cells

open access: yesAdvanced Healthcare Materials, EarlyView.
Cell membrane nanoparticles made with stromal cells are prepared and used to target leukemia cells. Deposition of the cell membrane onto rigid silica cores leads to increased uptake both in leukemia cell lines and primary cells from patients. These results show that nanoparticle rigidity affects the interaction between cell membrane nanoparticles and ...

An Organ‐on‐Chip Platform for Strain‐Controlled, Tissue‐Specific Compression of Cartilage and Mineralized Osteochondral Interface to Study Mechanical Overloading in Osteoarthritis

open access: yesAdvanced Healthcare Materials, EarlyView.
A mechanically active OsteoChondral Unit (OCU)‐on‐Chip platform mimicking the OCU's functional anatomy and the strain gradient across the osteochondral interface is presented. Upon compartment‐specific hyperphysiological compression, the model replicates mechanisms observed in osteoarthritis (OA) progression, such as calcium crystal accumulation ...
