Ultra‐Fine 3D Bioprinting of Dynamic Hyaluronic Acid Hydrogel for in Vitro Modeling

open access: yesAdvanced Materials, EarlyView.
3D bioprinting merges tissue engineering and additive manufacturing to create biological structures. A bioink is developed by modifying hyaluronic acid, a natural extracellular matrix polymer, with cysteine. Potassium iodide is later added to tune gelation kinetics, enabling fine printing with a 32G needle.

Bioxolography Using Diphenyliodonium Chloride and N‐Vinylpyrrolidone Enables Rapid High‐Resolution Volumetric 3D Printing of Spatially Encoded Living Matter

open access: yesAdvanced Materials, EarlyView.
Bioxolography, a novel volumetric 3D‐bioprinting technique, enables rapid and high‐resolution fabrication of >1 cm3 engineered living materials. A newly developed three‐component photoinitiator system significantly enhances the photoreactivity of gelatin methacryloyl‐based bioresins, allowing for precise xolographic bioprinting.

Mesenchymal stem cells for cartilage regeneration

open access: yesJournal of Tissue Engineering, 2020
Cartilage injuries are typically caused by trauma, chronic overload, and autoimmune diseases. Owing to the avascular structure and low metabolic activities of chondrocytes, cartilage generally does not self-repair following an injury. Currently, clinical

Carboxyl-modified single-wall carbon nanotubes improve bone tissue formation in vitro and repair in an in vivo rat model. [PDF]

open access: yes, 2014
The clinical management of bone defects caused by trauma or nonunion fractures remains a challenge in orthopedic practice due to the poor integration and biocompatibility properties of the scaffold or implant material. In the current work, the osteogenic

Harnessing Photo‐Energy Conversion in Nanomaterials for Precision Theranostics

open access: yesAdvanced Materials, EarlyView.
Harnessing photo‐energy conversion in nanomaterials enables precision theranostics through light‐driven mechanisms such as photoluminescence, photothermal, photoelectric, photoacoustic, photo‐triggered surface‐enhanced Raman scattering (SERS), and photodynamic processes. This review explores six fundamental principles of photo‐energy conversion, recent

Progress and prospect of technical and regulatory challenges on tissue-engineered cartilage as therapeutic combination product

open access: yesBioactive Materials, 2023
Hyaline cartilage plays a critical role in maintaining joint function and pain. However, the lack of blood supply, nerves, and lymphatic vessels greatly limited the self-repair and regeneration of damaged cartilage, giving rise to various tricky issues ...
