Biomimetic Mineralization of Keratin Scaffolds for Enamel Regeneration

open access: yesAdvanced Healthcare Materials, EarlyView.
Keratin‐based films guide biomimetic enamel remineralization by promoting organized hydroxyapatite growth under physiological conditions. Advanced biophysical characterization confirms keratin's structural adaptability and mineral ions‐binding affinity, supporting mineral nucleation and hierarchical crystal assembly. This study establishes keratin as a

Preparation of Bifunctional Orthosilicophosphate MgO‐CaO‐ZnO‐P2O5‐SiO2 Glasses: in vitro Evaluation of Antibacterial Activity and Osteoblast Gene Expression Behavior

open access: yesAdvanced Healthcare Materials, EarlyView.
Bifunctional ZnO‐containing orthosilicophosphate glasses (SPGs) composed mainly of orthotetrahedral groups with the unique glass network structure without long‐chain units are prepared via melt‐quenching. The glasses exhibit excellent antibacterial activity and upregulate the expression of osteogenic markers by releasing inorganic ions.

Beyond Bioactive Glass Composition: Using Morphology to Improve in Vitro and in Vivo Performance

open access: yesAdvanced Healthcare Materials, EarlyView.
Bioactive glasses can easily be shaped into granules, spheres, discs, fibers, or three‐dimensional scaffolds. The resulting morphology not only affects handling properties; it has a direct influence on various glass properties, including results of acellular immersion experiments or in vitro studies with cells or bacteria, but also on in vivo ...

Numerical Analysis of a Dental Zirconium Restoration and the Stresses That Occur in Dental Tissues

open access: yesApplied Bionics and Biomechanics, 2019
When it is about restorative dental materials, aesthetics is traditionally preferred. This has led to the selection of materials very visually similar to the enamel, but unfortunately, their mechanical properties are not similar.

Co‐Delivery of Ca‐MOF and Mg‐MOF Using Nanoengineered Hydrogels to Promote In Situ Mineralization and Bone Defect Repair: In Vitro and In Vivo Analysis

open access: yesAdvanced Healthcare Materials, EarlyView.
Metal‐organic frameworks (MOFs) have been synthesized using calcium (Ca‐MOF), magnesium (Mg‐MOF), and as hybrids (Ca/Mg‐MOF) for bone healing applications. MOFs are integrated into hydrogel polymer networks for injectable, sprayable, and coating applications.

Shedding Light on the Cellular Uptake Mechanisms of Bioactive Glass Nanoparticles as Controlled Intracellular Delivery Platforms: A Review of the Recent Literature

open access: yesAdvanced Healthcare Materials, EarlyView.
This review summarizes the main uptake pathways of bioactive glass nanoparticles (BGNs) and their intracellular localization, highlighting that BGNs are mainly internalized and entrapped within endosomes/lysosomes. Strategies for controlled intracellular ion release, with implications for targeted modulation of cell behavior, are discussed. The need to
