Inverse microemulsion route for synthesizing uniformly–distributed monodisperse calcium phosphate bioactive nanomaterials.

Dr. Vaishali Singh

Abstract :

Inverse microemulsion route is adopted to synthesize nanosized calcium phosphate particles. The technique uses a mixed surfactant system of Tween20 and Aliquat336 in order to obtain novel morphologies of the calcium phosphate nanocrystals. The nanopowders are extensively characterized by Fourier Transform Infra Red Spectroscopy, X– ray Diffraction, Scanning Electron Microscopy, and Transmission Electron Microscopy and are found to possess high crystallinity. TEM and SEM micrographs reveal the size and shape of the formed nanopowders. Lath shaped and spherical particles (average diameter 129nm) were obtained. Nature of surfactant and the precursor concentration play a significant role on the shape and morphology.
