tailieunhanh - Synthesis and characterization of AgNps using plant extracts

An attempted was made for the green synthesis of silver nanoparticles using commonly available plants viz., Tridax procumbans, Euphorbia hirta and Azardiract aindica. The plants yielding silver nanoparticles successfully were characterized and compared. It is concluded that the plant source of T. procumbans is most preferable for the synthesis of nanoparticles having smallest particle size with spherical shape, crystalline nature, stable silver elemental composition etc. | 2020 9 2 1939-1947 EXCELLENT PUBLISHERS International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 9 Number 2 2020 Journal homepage http Original Research Article https Synthesis and Characterization of AgNps Using Plant Extracts R.

It is concluded that the plant source of T. procumbans is most preferable for the synthesis of nanoparticles having smallest particle size with spherical shape crystalline nature stable silver elemental composition etc. Introduction Biological methods of nanoparticles synthesis using microorganisms like algae Lengke et al. 2006 bacteria Husseiny et al. 2007 fungi Gajbhiye et al. 2009 actinomycetes Ahmad et al. 2003 and plant or plant extracts Sumitra 2013 have been suggested as possible ecofriendly alternatives to chemical and physical methods. Using plants for nanoparticles synthesis can be advantageous over other biological processes by eliminating the elaborate process of maintaining cell cultures Shankar et al. 2004 . Further the green synthesis of AgNPs using plant sources which does not require the usage of high pressure energy temperature and toxic chemicals is considered as cost effective and ecofriendly .
