A research team from Purdue University has shown that carbon nanotubes could improve orthopedic prosthetic applications. ´
The team of researchers has shown through a series of experiments in petri dishes that bone cells adhere better to those materials whose lumps on the surface are smaller than the lumps found on the surface of the materials that are usually used. to make prostheses. In addition, as the lumps are smaller, the growth of more bone tissue is stimulated, which is essential to achieve correct adhesion of the implanted prosthesis.
Scientists have shown that creating implants with parallel alignment of carbon nanotubes and filaments promotes better cell growth and adhesion. This alignment mimics that of collagen fibers and natural ceramic crystals, hydroxyapatite, in real bones.
Two methods were used for the parallel alignment of the nanotubes. One through the application of electrical currents to a mixture of nanotubes and polymer, and the other through the use of one
