Item A preliminary study on green synthesis of silver nanoparticles using Annona glabra leaf extract(Institute of Chemistry Ceylon, 2019-05) Sithara,W. S; Wickramarachchi,S; De Silva,C. R; Aberathna,A. A. A .U; Amarasinghe,L .DIn this study, an eco-friendly, simple, rapid and a cost effective biological method for reducing Ag+ ions into silver nanoparticles (AgNPs) using the leaf extract of Annona glabra (A. glabra) plant has been developed. Although a number of plant extract mediated synthesis of AgNPs have been reported in the literature no previous attempt has been made on the use of A. glabra in the green synthesis of AgNPs.Item Enapsulation of lemongrass oil in chitosan: formulation and characterization(Institute of Chemistry Ceylon, 2018-05) Paragodaarachchi, Y; Wickramarachchi,SEssential oils are gaining increasing interest in food, pharmaceutical and agricultural industries due to their natural and safe status, wide acceptance by consumers, and multidimensional functional properties.
