Iranian Student Develops Magnetic Nanoparticles for Faster Healing of Bone Fractures
“Bone fractures are one of the common injuries that disrupt bone structure. When a bone is broken, it takes 6 to 15 weeks to fully heal. In this project, we plan to shorten the healing time of the bone,” Qazal Attari, an 11th grade student, told ANA.
“Recently, magnetic hyperthermia using by nanoparticles has been paid attention to in the world as an effective and new method for treating bone fractures; in this treatment method, magnetic nanoparticles are loaded into a scaffold prosthesis. The magnetic field creates local heat and speeds up healing,” she added.
“In this project, three nanoparticles of HAP, 2SiO and Fe3o4 are combined together and injected into the bone fracture site at the scaffold. Each of these nanoparticles has different properties, and the combination of all three of these nanoparticles accelerates the healing of the disease,” Attari said.
In a relevant development in March, specialists of a knowledge-based company had also managed to produce and commercialize nanostructured materials for bone regeneration with wide applications in dentistry, orthopedics and regenerative medicine.
“Biomimetic nanobone is the world's first bone-generating product in which both the organic and inorganic phases are nanometer and consists of self-assembled peptide nanofibers and nanohydroxyapatite,” said Shima Tavakkol, the managing director of the knowledge-based company.
“Accelerated bone generation without causing infection and inflammation is one of the main advantages of the biomimetic nanobone,” she added.
Noting that the product is mainly used for filling horizontal and vertical pores and rapid bone regeneration, Tavakkol said, “The Nanobone block has large internal pores and allows autologous proteins of the blood to enter the nanopores and the internal surface is completely covered.”
She added that the customers of this product are orthopedic surgeons, dentists, maxillofacial surgeons, periodontology and spine surgeons.
