Effective Intratumoral Retention of [103Pd]AuPd Alloy Nanoparticles Embedded in Gel‐Forming Liquids Paves the Way for New Nanobrachytherapy

As a new concept for brachytherapy, 103Pd‐radiolabeled gold‐palladium nanoparticles are hydrophobically coated and formulated in a carbohydrate‐based liquid. Upon injection, the liquid solidifies, forming brachytherapy‐seed like “nanogels”. The coating allows excellent retention of the nanoparticles in the gel, demonstrated both in vitro and in tumor‐bearing...

Dual‐Cues Laden Scaffold Facilitates Neurovascular Regeneration and Motor Functional Recovery After Complete Spinal Cord Injury

A dual‐cues laden hydrogel scaffold is able to synergistically promote vascular reformation and axon regeneration in the lesion epicenter post complete spinal cord injury (SCI). Moreover, implantation of the dual‐cues laden scaffold could also effectively reduce chondroitin sulfate proteoglycans and fibronectin deposition in the lesion area and improve...

Stabilization of Damaged Articular Cartilage with Hydrogel‐Mediated Reinforcement and Sealing

A modularly designed biomaterial approach is used to stabilize damaged articular cartilage. Interdigitating reinforcement of degenerated tissue with the hyaluronic acid‐based material improves multiscale mechanical properties and restores chondrocyte behavior. The biomaterial is then functionalized to improve mesenchymal stem/stromal cells (MSCs) adhesion...

Therapeutic Ultrasound Triggered Silk Fibroin Scaffold Degradation

Biomaterials are designed with set degradation profiles. However, some patients require fast degrading biomaterials to avoid an inappropriate immune response and fibrotic capsules; while others require slow degrading biomaterials to enhance cellular and vascular infiltration. Since predicting regenerative rate prior to implantation is currently not...
