Nanoparticles are now widely applied in products.
The synthesis of nanomaterials using biological
materials is an emerging field, notably for medical applications
because biologically derived compounds can be
safe. For instance, calcium phosphate is a natural biomineral
that possesses an excellent biocompatibility due to its
chemical similarity to human hard tissue such as bone and
teeth. Here, we synthesized calcium phosphate nanoparticles
by using bark extract of Spanish cherry (Mimusops
elengi). Calcium phosphate nanoparticles showed an
absorbance at 275 nm by UV–visible analysis and particle
size of 25 nm by nanoparticle tracking and analysis.
