Kashan University synthesizes controlled nanostructures

Numerous methods have so far been reported for the production of hydroxyapatite due to the wide applications of this material. However, this research tries to present a simple method that can control the shape and size of hydroxyapatite particles at nanometric scale.

In addition, the temperature and time of reaction are relatively low in comparison with those of other reported methods.

Dr. Fatemeh Mohandes, one of the researchers, said the main purpose of the research was to control the shape and size of hydroxyapatite nanostructures, for which various methods and surfactants have been used.

“We succeeded in producing hydroxyapatite nanostructures, including nanorods and nanoparticles, through this method by using Schiff-base organic compounds. The use of Schiff-base compounds had not been reported for controlling the shape and size of hydroxyapatite nanostructures,” she said.

“Our research team successfully used these compounds under the supervision of Prof. Mas'oud Salavati Niyasari."

Results obtained from the characterization of the product showed that the synthesized materials have high purity and efficiency.

Studying the bioactivity of hydroxyapatite nanostructures synthesized through this method shows that one-dimensional nanostructures (nanorods) have higher biological activity compared to zero-dimensional nanostructures (nanoparticles).
