The document is an abstract submission about the synthesis of metal nanoparticles using biological systems. It discusses how the biological synthesis of silver nanoparticles using leaves of Andrographis paniculata is more eco-friendly than chemical methods. The silver nanoparticles produced were characterized using UV spectroscopy, XRD analysis and SEM, and were found to be between 35-55nm in size. The nanoparticles demonstrated antiplasmodial and anti-parasitic properties.

R.FASEEHA FATHIMA III B.Sc BIOCHEMISTRY HOLY CROSS COLLEGE, TRICHY – 2 Synthesis of metal nanoparticles using biological systems The synthesis of metal nanoparticles using biological systems is an expanding research area where it finds its use as nanomedicines. Nano particles synthesized by chemical methods are not eco – friendly. The biological synthesis of silver particles is convenient and environmentally safe. Silver nanoparticles were synthesized from AgNo3 by using the leaves of Andrographis paniculata. The obtained nanoparticles were characterized using UV spectroscopy, X-ray diffraction analysis and Scanning electron microscope. The particle size was found to be 35 – 55 nm by means of XRD AND SEM. The antiplasmoidal activity of these nanoparticles was studied against Plasmodium falciparum. It was also found to have anti – parasitic properties. The important outcome of this study will be the development of value added products from medicinal plants of India for biomedical and nanotechnology based industries. Andrographis paniculata reduce the number of aberrant cells and frequencies of aberration per cell at each concentration and duration of exposure in vivo Keywords – silver nanoparticles, anti – parasitic activity , UV, XRD and SEM.
