3D‐Printed Scaffolds Promote Enhanced Spinal Organoid Formation for Use in Spinal Cord Injury

open access: yesAdvanced Healthcare Materials, EarlyView.
3D‐printed organoid scaffolds with microscale channels are developed to enhance spinal cord injury recovery by guiding region‐specific spinal neural progenitor cells. These scaffolds promote axonal growth, cell maturation, and neuronal network formation.

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 ...

Rolling Ultrasharp Microneedle Spheres Enable Topical Delivery of Biologics Through the Skin

open access: yesAdvanced Healthcare Materials, EarlyView.
Rolling ultraminiaturized microneedle spheres (RUMS), created via two‐photon polymerization, unlock effective and painless topical delivery of messenger RNA (mRNA) and drugs through the skin. By gently forming thousands of microscopic pores, RUMS boost skin permeability by up to 100‐fold.

A Deployable 4D Printed, Mucoadhesive and Magnetically Guided Patch for Local Therapy of Gastric Cancer

open access: yesAdvanced Healthcare Materials, EarlyView.
A new perspective for treatment of gastric cancer is proposed utilizing 4D printing to develop shape morphing, deployable, and magnetically guided local drug releasing patches. The deployed patches are envisioned to adhere at the tumor site to locally deliver high drug amounts.

Biologically Active Implants Prevent Mortality in a Mouse Sepsis Model

open access: yesAdvanced Healthcare Materials, EarlyView.
A modular, triple‐action titanium implant is developed to prevent implant‐associated infections by repelling bacteria, killing pathogens, and enhancing tissue integration. Coatings with phage cocktails targeting P. aeruginosa and S. aureus show significant bacterial reduction and improved survival in a mouse sepsis model.

Programmed Aggregation of Lipidated Nitrobenzoselenadiazole as a Photo‐Activatable Pyroptosis Inducer

open access: yesAdvanced Healthcare Materials, EarlyView.
This study presents alkylated nitrobenzoselenadiazole (NBSD) photosensitizers that self‐assemble into programmable aggregates, enabling photo‐triggered pyroptosis and enhanced ROS generation. The lead compound, NBSD‐NOc, exhibits superior photodynamic activity, high cellular uptake, and implantable gel compatibility with pH‐responsive release.

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 ...
