Nanoparticles are substances with at least one-dimension size from 1 to 100nm. These<br/>nanosized-particles have a lot application which includes antimicrobial agent, catalyst,<br/>optical sensing. This study focused on the green synthesis of metallic nanoparticles<br/>particularly CuO and Ag nanoparticles using the leaves extract of Eclipta prostata (false<br/>daisy) as reducing and stabilizing agent. The synthesized nanoparticles were initially<br/>characterized using UV-Vis spectroscopy to determine their optical properties. Also, this<br/>was used to confirm the presence of silver nanoparticles which exhibited an absorption at<br/>434nm, which correspond to its surface plasmon resonance. SEM analysis showed that<br/>both CuO and Ag nanoparticles have quasi-spherical morphology. EDX analysis identifies<br/>the presence of Cu, O for CuO nanoparticles and Ag for Ag nanoparticles. Moreover, the<br/>presence of elemental C is associated with the organic molecules from the leaves extract<br/>which serves as capping agent of the nanoparticles. This were further confirmed by FTIR<br/>analysis which shows several functional group peaks common to organic molecules. The<br/>antimicrobial activity of both CuO and Ag nanoparticles was tested against E. coli and S.<br/>aureus. Only Ag nanoparticles showed exhibited antimicrobial activity against both<br/>microbes. The catalytic property of both CuO and Ag nanoparticles was evaluated using<br/>the test dye methylene blue. Both metal nanoparticles showed promising catalytic<br/>performance in decolonizing the dye. About 82% and 95.2% of dye were for 60 seconds<br/>using CuO and Ag nanoparticles, respectively. |
