Synthesis of Zinc Oxide and Chromium (III) Oxide Nanoparticles with Diverse Physiological Properties

Abstract

The use of an inorganic phase in water-in-oil (w/o) microemulsion has received considerable attention recently for preparing metal oxide nanoparticles. This is a technique, which allows preparation of ultrafine metal oxide nanoparticles within the size range 40 to 80 nm. Preparation of nano ZnO and Cr₂O₃ studied, investigated in the inverse microemulsion system. Therefore the nucleation of metal particles proceeds in the water capsules of the microemulsion. Zinc oxide and Chromium (III) oxide nanoparticles powder has traditionally been used as a pigment and diverse physiological properties. Physiologically important nanoparticles are currently under investigation for their bio-medical applications as well as for therapeutics.
