Sustainable Catalyst‐Free PLG Networks: Recyclability, Biodegradability, and Functional Performance

open access: yesAdvanced Functional Materials, EarlyView.
A catalyst‐additive free covalent adaptable network is developed from star‐shaped poly(lactide‐co‐glycolide) cross‐linked with pyromellitic dianhydride, enabling internal carboxylic acid‐driven transesterification. The resulting biodegradable network exhibits mechanical robustness (Young's modulus ≈1.6 GPa), complete recyclability, rapid biodegradation

Vibration‐Mediated Recovery of Irradiated Osteocytes and Their Regulatory Role in Breast Cancer Bone Metastasis

open access: yesAdvanced Healthcare Materials, EarlyView.
Radiotherapy damages bone and disrupts osteocyte function, yet mechanically mediated protection remains largely unexplored. This study demonstrates that low‐magnitude, high‐frequency (LMHF) vibration mitigates irradiated osteocyte apoptosis, restores their ability to regulate breast cancer extravasation, and acts synergistically with radiotherapy to ...

Xeno‐Free Biocompatible Peptide‐Based Bioinks Reinforced with Cellulose Nanofibers for 3D Printing

open access: yesAdvanced Healthcare Materials, EarlyView.
A xeno‐free bioink combining self‐assembled peptides and cellulose nanofibers is developed for 3D printing. The bioink forms a non‐cross‐linked 3D scaffold, mimicking the extracellular matrix and supporting over 95% cell viability. This approach offers enhanced biocompatibility and mechanical stability, advancing 3D printing for personalized medicine ...
