The utilization of biological systems has emerged as a novel method for the synthesis of nanoparticles. Nanoparticles are defined as particles between 1nm to 100nm in size, some defining them up to 1 micron. Nanoparticles exhibit unique properties in terms of photoemission, conductivity and catalytic activity when compared to their respective bulk materials. The applications of these small particles are defined in a bigger way in different biological studies. Synthesis of nanoparticles using plant extract is a recent advancement in the field of plant biotechnology because it yields an eco-friendly method of nanoparticle synthesis. Recently synthesis of nanoparticles has been reported utilizing the plant extracts and their biomass. It opens up a new venue for using the plants for the synthesis of various metal nanoparticles in large scale. Here, we review the plants already exploited for the synthesis of nanoparticles and possible uses of plant resources as a nanofactories to synthesize less toxic metal nanoparticles. Further studies on the mechanism of nanoparticle synthesis in plants in the cellular level and the possible extracellular synthesis of nanoparticles using plant extract in large scale would revolutionize the field of Plant Biotechnology in Nanoscience. © 2009 Society for Biology and Biotechnology.
