Giving It a Twist: One‐Step Fabrication of Aligned Biomimetic Yarn Scaffolds via Rotational Melt Electrofibrillation

Advanced Healthcare Materials, EarlyView.
Due to its multifunctionality, replicating the fibrillar and supramolecular architecture of Collagen I is gaining increasing priority in regenerative medicine. Using rotational Melt Electrofibrillation, we present a powerful method to accurately mimic the ultrastructure of Collagen with polycaprolactone, enabling the one‐step fabrication of three ...

Nano‐Engineered Titanium Implants Loaded With Gingival Fibroblasts‐Derived Microvesicles Enhance Early Osseointegration And Soft Tissue Attachment In Vivo

Advanced Healthcare Materials, EarlyView.
Our study showed that human primary gingival fibroblast–derived microvesicles on nano‐engineered titanium implants promote early osseointegration and soft‐tissue attachment in vivo. ABSTRACT Titanium dental implants require both reliable osseointegration and peri‐implant soft tissue seal formation to ensure long‐term success. While osseointegration has

Ti6Al4V‐Bioglass‐Copper Composites for Load‐Bearing Implants

Advanced Healthcare Materials, EarlyView.
We have designed and manufactured a novel Ti64‐based composite by adding 45S5 bioglass (BG) and copper (Cu). Adding BG on titanium improves wear resistance and biocompatibility, whereas Cu addition improves mechanical strength while providing inherent lifelong bacterial resistance.

3D‐Printed Titanium Implants with Bioactive Peptide‐Polysaccharide Scaffolds for Personalized Bone Reconstruction

Advanced Healthcare Materials, EarlyView.
Porous 3D‐printed titanium implants are made bioactive by integration with a supramolecular peptide‐hyaluronic acid nanofibrillar scaffold, without the addition of exogenous cells or growth factors. Uniform filling of the implant architecture promotes vascularized, spatially homogeneous bone regeneration, significantly enhancing osteogenesis throughout
