Biosynthesis of Lanthanide based Cobalt Metal Oxide Magnetic Nanoparticles Applications in Catalysis Magnetic and Biological Activity

Abstract

newline In the present decade synthesis of magnetic nanoparticle using green approach is much newlineattraction due to the cost effective, eco-friendly and high potential nanoparticles. These newlinenanoparticles become biocompatible as compare to physical and chemical synthesis newlinemethods. Some of the area that effect the life such as storage device, magnetic newlinerefrigeration, catalysis, electrochemical energy storage, drug delivery, MRI and CT newlinescan, anticancer, hyperthermia, ceramic material and environmental remediation. In the newlinepresent study medicinal plant Jatropha-curcas L, and Hedychium coronarium newline(Gulbakawali) plant leave extract use for the magnetic nanoparticles (MNPs). This is newlinethe first time using the above plant extract for the biosynthesis of Lanthanum, newlineGadolinium, Dysprosium rare earth and transition metal Cobalt based bimetallic MNPs. newlinePlant leaf extract working as a reducing as well as capping agent and no need to further newlineadded the capping agent. While the chemical reducing and capping agent having some newlinetoxic effect on human and aquatic life of environment. Bimetallic nanoparticle having newlineunique physical properties such as quantum effect, high surface area and mobility, newlinechemical, mechanical, optical, catalytic and magnetic property. These unique properties newlinedistinguish the bimetallic from their monometallic counterparts and more effectively in newlinecomparing to individual metals. newlineTherefore, we are interesting for the synthesis of bimetallic nanoparticles. The synergic newlineeffect of the two metals makes its unique. Bimetallic nanoparticle can be used newlinepreliminary as Single molecule magnetic properties along with therapeutic and in newlinemedicinal purpose. The biocompatibility of the two metals improving the efficiency newlineand reduced the adverse effect on cell. The details research work are discussed as newlinechapter wise in the following. newline
