The influence of multi-stenosis in the left coronary artery subjected to the variable blood flow rate [PDF]
Frontiers in Engineering and Built Environment, 2021 Purpose – Coronary artery disease (CAD) is reported as one of the most common sources of death all over the world. The presence of stenosis (plaque) in the coronary arteries results in the restriction of blood supply, leading to myocardial infarction ...

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 ...

Biomimetic Cell Membrane‐Coated Scaffolds for Enhanced Tissue Regeneration
Advanced Materials, EarlyView.This review examines the development and use of cell membrane‐coated scaffolds in tissue engineering. Bioinspired phospholipid and glycocalyx coatings enhance anti‐fouling, anti‐thrombogenic, and selective molecular recognition properties. Native cell membrane coatings further support cell‐specific interactions, immune modulation, and reduced bacterial

Flow Analysis in Pathological Microvascular Models by Ultrasound Localization Microscopy
Advanced Materials Technologies, EarlyView.This study presents a new platform combining ultrasound localization microscopy with biomimetic gelatin phantoms to analyze flow dynamics in small vessels with narrowing or obstructions. Using microbubble tracking, the method enables high‐resolution velocity mapping in 100–500 µm channels, revealing flow changes in pathological microvascular conditions
