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

Advanced 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 ...

Molecular defects of the platelet P2 receptors [PDF]

Purinergic Signalling, 2011
Human platelets express three types of P2 receptors, which play important roles in platelet function: P2X(1), P2Y(1) and P2Y(12). Only patients with either quantitative or qualitative abnormalities of the platelet P2Y(12) receptor have been well-characterized so far.

Flexible Selenium Nanowires with Tuneable Electronic Bandgaps

Advanced Materials, EarlyView.
Nanotubes serve as effective test tubes for selenium nanowires, as their diameter precisely controls the width of the nanowires and the Se─Se bonding, resulting in a variety of different structures. An electron beam can be used to modify the nanotubes, allowing real‐time observation of the nanowire extrusion process. Additionally, optically transparent
