JOURNAL OF ADVANCED APPLIED SCIENTIFIC RESEARCH http://mail.joaasr.com/index.php/joaasr <p>Journal of advanced applied scientific research (JOAASR) is an entrenched podium for scientific exchange among applied scientific research. The journal aims to publish papers dealing with novel experimental and theoretical aspects of applied scientific research. The focus is on fundamental and advance papers that understanding of applied scientific research. JOAASR incorporates innovations of the novel theoretical and experimental approaches on the quantitative, qualitative and modeling of advanced scientific concepts.</p> Jamal Mohamed College Publication en-US JOURNAL OF ADVANCED APPLIED SCIENTIFIC RESEARCH 2454-3225 Synthesis of silver oxide nanoparticles using aqueous leaf extracts of Viscum orientale Willd, Coleus amboinicus Lour and evaluation of their antibacterial activity http://mail.joaasr.com/index.php/joaasr/article/view/738 <p>The objective of this study was to develop a straightforward biological synthesis of &nbsp;silver oxide nanoparticles (Ag<sub>2</sub>O NPs) using aqueous leaf extract of <em>Viscum orientale</em> Willd and <em>Coleus amboinicus </em>Lour as a good lowering and capping agent&nbsp;. The UV–visible bands observed at 499 and 451 nm was confirmed the creation of nanosized Ag<sub>2</sub>O particles making use of <em>Viscum</em><em> orientale </em>Willd and <em>Coleus amboinicus </em>Lour plants. The formation of Ag<sub>2</sub>O stretching frequency was confirmed by FTIR spectral studies. Scanning electron microscopy and EDAX analysis displayed&nbsp; Ag<sub>2</sub>O nanoparticles have been pure and spherical shaped and had been the variety of length from 35±2 nm for (Ag<sub>2</sub>O NPs) by the usage of <em>Viscum orientale</em> Willd and 32±2 nm for (Ag<sub>2</sub>O NPs) <em>Coleus amboinicus</em> Lour vice-versa. The fashioned nanoparticles have been cubic in association and face-centered cubic in form, consistent with X-ray diffraction studies. The shaped green kind Ag<sub>2</sub>O NPs confirmed ambitious antibacterial&nbsp; against each gram possitive and gram negative bacteria.</p> M. Karthikeyan P. Vijaya Kumar A. Jafar Ahamed A.
