OA cartilage derived chondrocytes encapsulated in poly(ethylene glycol) diacrylate (PEGDA) for the evaluation of cartilage restoration and apoptosis in an in vitro model.

Histology and histopathology, 2011
Osteoarthritis (OA) is characterized by cartilage attrition, subchondral bone remodeling, osteophyte formation and synovial inflammation. Perturbed homeostasis caused by inflammation, oxidative stress, mitochondrial dysfunction and proapoptotic/antiapoptotic dysregulation is known to impair chondrocyte survival in joint microenvironments and contribute

4D Printing of Self‐Immolative Polymers

Advanced Functional Materials, EarlyView.
The integration of self‐immolative polymers (SIPs) into light‐based 3D printed structures is presented as a new “living” 4D printing strategy. By exploiting their metastability and stimuli‐responsiveness, SIP‐containing printed objects can undergo rapid and triggered degrowth under ambient conditions and subsequent regrowth through polymer ...

Shape‐Morphing Nanoengineered Hydrogel Ribbons as Hemostats

Advanced Functional Materials, EarlyView.
This study introduces a self‐assembling, shape‐morphing nanoengineered hydrogel ribbon system that rapidly forms porous aggregates in situ for efficient hemostasis in trauma and surgical applications. Abstract Rapid and effective hemorrhage control remains a major challenge in trauma and surgical care, particularly for complex or noncompressible wounds.
