Development of Magneto-Organogel and Study of Gold Nanoparticles Growth

Abstract

The current research project work basically deals with two areas- iron oxide nanoparticles and gold nanoparticles. Synthesis of magnetic nanoparticles was carried out using co-precipitation method and then oleylamine functionalized Fe3O4 nanoparticles were synthesized by thermal decomposition method. Oleylamine capping not only prevented the aggregation of nanoparticles but also made the nanoparticles soluble in organic mediums such as hexane; chloroform etc. in order to make the nanoparticles suitable for organogel formation. We have reported two types of magneto-organogels; one based on oleic acid while the other based on soybean oil and their characterization was carried out using XRD, FESEM, FTIR and microscopic analysis. The release kinetics studies and preliminary impedance analysis projects the magneto-organogels as potential agents for controlled drug delivery systems. Study on the growth of gold nanoparticles was carried out separately using hydroquinone; green tea and chromium chloride respectively. We have reported the synthesis of gold nanoparticles of different shapes and sizes which was confirmed by different characterization techniques such as UV-visible, XRD, FESEM, DLS and Zeta potential analysis
