Engineering Flexible Nanofibrous Hydroxyapatite Scaffolds With Tunable Degradation and Mechanical Properties for Bone Regeneration

Small, EarlyView.
Conventional hydroxyapatite ceramics are brittle and poorly resorbable, limiting their use in bone repair. To overcome these limitations, flexible scaffolds are fabricated using ceramic nanofibers as structural building blocks. Adjusting nanofiber characteristics allows modulating the mechanical properties and degradation, providing a versatile ...

A Luminescent PEI/Cy5‐Citrate‐Functionalized Carbonated Apatite Nanoplatform for In Vitro Gene Delivery and In Vivo Traceability

Small, EarlyView.
A luminescent PEI/Cy5‐citrate‐functionalized carbonated apatite nanoplatform combines biocompatibility, plasmid delivery, and Cy5‐based traceability. The system enables effective in vitro gene delivery while preserving cell viability and allows real‐time in vivo fluorescence tracking of the nanocarrier.

Engineering an Enzymatically Active Granular Matrix for On‐Chip Modeling of Bone‐Like Mineralization

Small, EarlyView.
Alkaline phosphatase (ALP)‐functionalized poly(ethylene glycol) (PEG) microgels assemble into a perfusable granular matrix for cell‐free modeling of bone‐like mineralization. Microgel‐associated enzymatic activity promotes calcium phosphate deposition, producing a calcium‐deficient, poorly crystalline apatite‐like phase, while keeping interparticle ...

Synthesis, modification, and chlorhexidine loading of polymer modified‐HM‐HAP particles: In vivo antibacterial analysis and cell cytotoxicity assessment

Smart Molecules, EarlyView.
This study presents the synthesis of hollow mesoporous hydroxyapatite (HM‐HAP) particles modified with different weights PEG and PEI. Chlorhexidine was loaded onto the particles. SEM analysis confirmed no significant morphological changes. Antibacterial activity was tested in vitro and in vivo using mouse oral bacteria, demonstrating promising results.

Progress in bone tissue engineering biomaterials: Development, challenges, and prospects

VIEW, EarlyView.
Scheme 1 Application of biomaterials in immunomodulation during bone tissue engineering. Abstract Bone defect repair remains a major clinical challenge in orthopedics. Over 2 million cases caused by trauma, tumors, and other factors occur annually, with large‐scale defects posing a particular bottleneck due to limited self‐healing capacity.

Details on synthetic apatites formed through bacterial mediation. Mineralogy and chemistry of the products. Détails sur les apatites synthétiques formées par action bactérienne. Minéralogie et chimie des produits obtenus

, 1989
La synthèse de l'apatite par activité bactérienne est réalisée, dans l'eau douce et dans l'eau de mer, soit par remplacement d'un précurseur carbonaté, soit par précipitation à partir d'une solution d'ARN hydrolysée par CaCO₃. Les influences du magnésium
