Impact of Fiber Orientation in Electrospun PLA Scaffolds on Fluid Dynamics in a Custom Microfluidic Device

open access: yesAdvanced Healthcare Materials, EarlyView.
Fiber orientation in electrospun scaffolds affects permeability and fluid dynamics in microfluidic devices. Combining experimental data with computational fluid dynamic simulations, we show that aligned fibers enhance flow uniformity, reduce pressure and shear stress variability.

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 ...

Combination of Polydopamine and Plasma Oxidation to Increase Tissue Integration of Polyurethane‐Silicone Copolymers for Cardiovascular Implants

open access: yesAdvanced Healthcare Materials, EarlyView.
Plasma oxidation following polydopamine deposition can significantly reduce the surface hydrophobicity of polyurethane‐siloxanes without impacting surface roughness, thereby increasing fibroblast viability, adhesion, and extracellular matrix production and secretion.

Biofabrication of a Filtration Barrier by Integrating Electrospun Membranes and Flow in a Glomerular Co‐Culture

open access: yesAdvanced Healthcare Materials, EarlyView.
An ex vivo glomerular filtration barrier is engineered using electrospun, biomimetic membranes seeded with human glomerular cells. The model supports fenestrated endothelium and podocyte foot processes under flow, mimics size‐selective filtration, and enables disease modeling with hiPSC‐derived podocytes, offering a powerful platform for studying ...

Interstitial N‐Strengthened Copper‐Based Bioactive Conductive Dressings Combined with Electromagnetic Fields for Enhanced Wound Healing

open access: yesAdvanced Healthcare Materials, EarlyView.
This study developed a nitrogen‐strengthened copper‐iron‐zinc (N‐CuFeZn) alloy bioactive dressing integrated with electromagnetic stimulation. The coaxial dressing, made from 0.04 mm filaments with 1120 MPa tensile strength, showed that electromagnetic activation enhanced therapeutic outcomes by increasing VEGF expression, promoting angiogenesis (2.1 ...

Tumor Microenvironment‐responsive Nanocatalyst for Targeted Chemodynamic Cancer Therapy

open access: yesAdvanced Healthcare Materials, EarlyView.
An Tumor microenvironment‐responsive nanocatalyst system composed of PLGA‐encapsulated Ca–Fe peroxide and polyarginine enables sustainable Fenton reaction in tumors. Low levels of H2O2 (50–100 µm) initiate the nanoparticle degradation, while polyarginine‐derived nitric oxide accelerates Fe3+ reduction, leading to self‐amplifying •OH generation for ...

Antitumoral Efficacy of AuNRs‐Laden ECFCs In Vitro and In Vivo: Decoding the Heat and Rays Combo Treatment in Breast Cancer and Melanoma Cells

open access: yesAdvanced Healthcare Materials, EarlyView.
Endothelial Colony Forming Cells (ECFCs) acted as cellular cyborgs, stealthily transporting gold nanorods (AuNRs) into tumors to enable targeted near‐infrared (NIR) hyperthermia combined with radiotherapy. This approach triggers ferroptosis in melanoma and inhibits autophagy in breast cancer, revealing a tumor‐specific response to nanomaterial‐assisted
