  • Title: Biosynthesis of silver nanoparticles using Eclipta leaf.
    Author: Jha AK, Prasad K, Kumar V, Prasad K.
    Journal: Biotechnol Prog; 2009; 25(5):1476-9. PubMed ID: 19725113.
    Abstract:
    A green, low-cost and reproducible Eclipta leaves negotiated synthesis of silver nanoparticles is reported. The synthesis is performed at room temperature. X-ray and transmission electron microscopy analyses are performed to ascertain the formation of Ag nanoparticles. Nanoparticles almost spherical in shape having a size of 2-6 nm are found. UV-visible study revealed the surface plasmon resonance at 419 nm. The lattice strain is estimated to be 0.0045 using Williamson-Hall approach. The use of Eclipta for the synthesis of silver nanoparticles offers the benefit of ecofriendliness and amenability for large scale production through scaling up.
