Functional calcium phosphate composites in nanomedicine

Area of Science:

• Biomaterials Science
• Nanomedicine
• Materials Chemistry

Background:

• Calcium phosphate (CaP) is nature's mineral in bones and teeth, existing in nanostructured forms.
• CaP exhibits remarkable stoichiometric flexibility, pH-dependent stability, and dynamic surface ions.
• These properties make CaP a highly versatile material for nanomedical applications.

Purpose of the Study:

• To review guidelines for synthesizing CaP composites in aqueous media.
• To highlight how functional units influence CaP's crystallinity, morphology, size, and properties.
• To showcase CaP's applications in nanomedicine.

Main Methods:

• Review of synthetic routes for CaP composites using templating molecules (surfactants, polymers).
• Exploration of how functional units direct CaP synthesis and impart desired properties.
• Illustration of laboratory examples involving CaP functionalization.

Main Results:

• Functional units like surfactants and polymers can guide CaP synthesis.
• Tailored crystallinity, morphology, and size of CaP composites are achievable.
• CaP can be functionalized with biologically active polymers or integrated into responsive hydrogels.

Conclusions:

• Aqueous synthesis routes offer control over CaP composite characteristics.
• Functional units are key to developing CaP materials for specific nanomedical needs.
• CaP composites show promise for advanced therapeutic and diagnostic applications.
