Preparation of protamine-adsorbed calcium phosphate powders and their antibacterial property

Journal of Asian Ceramic Societies, 2022
Calcium phosphates are key biomaterials in bone regeneration and dental treatment fields. Biomaterials must exhibit antibacterial properties to ensure protection against microbial infection in implantation frameworks.

Estudo da influência dos íons K+, Mg2+, SO4(2-) e CO3(2-) na cristalização biomimética de fosfato de cálcio amorfo (ACP) e conversão a fosfato octacálcico (OCP) Study of the influence of K+, Mg2+, SO4(2-) and CO3(2-) ions in the biomimetic crystallization of amorphous calcium phosphate (ACP) and conversion into octacalcium phosphate (OCP)

Química Nova, 2007
The crystallization of hydroxyapatite (HA) in aqueous solution can be described by the mechanism ACP -> OCP -> HA. In this work, it was studied the influence of K+, Mg2+, SO4(2-) and CO3(2-) ions in the formation of ACP and in its conversion to OCP ...

Comparative Physicochemical Characterization of Two Commercial Hydroxyapatite‐Based Collagen Biostimulators

International Journal of Ceramic Engineering &Science, Volume 8, Issue 4, July 2026.
Direct, multimodal characterization reveals that two commercial HA–collagen biostimulators share a hydroxyapatite–dominant composition and similar crystalline structure, with ≈$ \approx $30 µm HA spheres and near‐physiological pH. Differences arise mainly from the gel matrix—Na‐CMC and glycerol—driving subtle rheology and tonicity variations.

Biomimetic fabrication of calcium phosphate/chitosan nanohybrid composite in modified simulated body fluids

eXPRESS Polymer Letters, 2017
In this study, nucleation and growth of bone-like hydroxyapatite (HAp) mineral in modified simulated body fluids (m-SBF) were induced on chitosan (CS) substrates, which were prepared by spin coating of chitosan on Ti substrate.

Protein and Peptide Inhibitors of Mineralization: A Systematic Review of In Vitro Studies

Journal of Peptide Science, Volume 32, Issue 7, July 2026.
In vitro evidence from crystallization assays demonstrates that peptides inhibit mineral nucleation and crystal growth through sequence‐dependent interactions (acidic residues and phosphorylation) with mineral surfaces. In cell cultures, these molecules reduce calcium deposition and ALP activity and modulate the expression of biomineralization‐related ...

Formation of Stable Amorphous Calcium Phosphate and Collagen Assemblies by a Versatile Spray‐Drying Approach

Advanced Functional Materials, Volume 36, Issue 46, 8 June 2026.
Amorphous calcium phosphate (ACP) microparticles with long‐term and thermal stability are prepared with or without collagen using a scalable one‐pot spray‐drying process. Under simulated physiological conditions, they crystallize into biomimetic bone mineral and, when combined with collagen, form extrudable, fibrillar bone‐like 3D constructs.
