Abstract
Well-characterized, monodispersed biomimicking nanocavities formed by Aerosol OT (AOT) reverse micelle in H2O/ AOT / heptane at ω =10 (ω = [H2O]/[Surfactant]) was implemented to prepare Lanthanum oxalate (LaOx) nanoparticles employing intermixing of two microemulsions technique. The formed nanoparticles of LaOx have been characterized by the UV-visible, Transmission Electron Microscopy (TEM) as well as by Fourier Transformed Infrared (FTIR) spectroscopy. UV-visible and FTIR spectroscopic measurements confirm the formation of LaOx nanoparticles. TEM measurements show that the reverse micellar entrapped nanoparticles were spherical in shape.
