Lemongrass Oil Containing Chitosan Microcapsules by Ionotropic Gelation

Paragodaarachchi, Y.L.; Wickramarachchi, S.R. (Asian Journal of Chemistry, 2022)

Ionotropic gelation using sodium tripolyphosphate (STPP) as the crosslinker was successfully used to formulate lemongrass oil containing chitosan microcapsules. Formation of oil in aqueous chitosan polymer solution was ...
Synthesis of Annona glabra Mediated Silver Nanoparticles, their Photocatalysis and Toxicity on Daphnia magna

Wickramarachchi, S.R.; Paragodaarachchi, Y.L.; De silva, C.R.; Perera, A.D.L.C.; Amarasinghe5, I.D. (Asian Journal of Chemistry, 2023)

This work reports the synthesis of silver nanoparticles (AgNPs) using the leaf extract of Annona glabra as a green synthetic route and assessment of its photocatalytic property using methelyne blue as a model dye and toxic ...
Toxic potential of green synthesized silver nanoparticles using Annona glabra leaf extract against Daphnia magna

Paragodaarachchi, Y.L.; Wickramarachchi, P.A.S.R.; De Silva, C.R.; Amarasinghe, L.D. (Proceedings of the 1st International Conference on Frontiers in Chemical Technology, Institute of Chemistry Ceylon, 2020)

This study aims to evaluate the acute toxicity of biosynthetic AgNPs produced using Annona glabra leaf extract, against a selected aquatic-indicator, Daphnia magna. The toxicity of the biosynthetic AgNPs was compared against ...
