Application of calcium phosphatenanoparticles in biomedicine

Calcium phosphate has excellent biocompatibility due to its chemical similarity to human hard tissue (bone and teeth). In nanoparticulate dispersed form, it can be used as a carrier in biological systems, e.g. to transfer nucleic acids or drugs. If such nanoparticles are suitably functionalized with fluorescing dyes, they can also be used for imaging or for photodynamic therapy.
