Extracellular Vesicle Crosslinkers Constructing Hydrogels with Stress‐Relaxation and Bioactive Protein Modification

open access: yesAdvanced Materials Interfaces, EarlyView.
Extracellular vesicles (EVs) are functionalized and used as crosslinkers to construct hydrogels, compatible with common crosslinking chemistries in biomaterial scaffolds. EV crosslinkers provided stress relaxation properties, promoting cell growth. They also enabled efficient protein delivery while maintaining biological activity, as VEGF‐loaded EV ...

Rethinking Diffusion-Based Image Generators for Fundus Fluorescein Angiography Synthesis on Limited Data [PDF]

open access: yesarXiv
Fundus imaging is a critical tool in ophthalmology, with different imaging modalities offering unique advantages. For instance, fundus fluorescein angiography (FFA) can accurately identify eye diseases. However, traditional invasive FFA involves the injection of sodium fluorescein, which can cause discomfort and risks.

Aqueous Synthesis of Poly(ethylene glycol)‐Amide‐Norbornene‐Carboxylate for Modular Hydrogel Crosslinking

open access: yesAdvanced Materials Interfaces, EarlyView.
An all aqueous synthesis of poly(ethylene glycol)‐amide‐norbornene‐carboxylate (PEGaNBCA) is developed via reacting carbic anhydride with amino‐terminated PEG. PEGaNBCA is readily crosslinked into hydrogels by click chemistries. PEGaNBCA crosslinked thiol‐norbornene hydrogels are hydrolytically stable but can be rendered hydrolytically labile through ...

Durable Bio‐Based Nanocomposite Coating on Urinary Catheters Prevents Early‐Stage CAUTI‐Associated Pathogenicity

open access: yesAdvanced Materials Interfaces, EarlyView.
A stable bio‐based nanocomposite coating for urinary catheters is developed using a simple, environmentally‐friendly sonochemical process. The coating, integrating antimicrobial, antibiofilm, and antioxidant properties, effectively tackled multiple early‐stage pathogenic factors associated with catheter‐associated urinary tract infections.

A Dynamic Double‐Flow Gut‐On‐Chip Model for Predictive Absorption Studies In Vitro

open access: yesAdvanced Materials Technologies, EarlyView.
This study presents a novel millifluidic gut‐on‐chip model using the MIVO® device to replicate human intestinal conditions. Dynamic co‐culture of CaCo‐2 and HT‐29 cells accelerates differentiation, modulates mucus thickness, and enhances barrier function.

4D Printed Self‐Deploying Bio‐Based Scaffolds for the Regeneration of Endoluminal Tissue

open access: yesAdvanced Materials Technologies, EarlyView.
A bilayer self‐deploying tubular C‐shaped scaffold, made of natural polymers and triggerable by humidity, is fabricated via 4D printing for the regeneration of gastro‐intestinal tissue. The choice of the materials and their spatial arrangement is guided by physical and biological evaluation, whereas the geometry of the structure is optimized through ...
