Morphological Fabrication of Immobilized Green Synthesized Silver Nanoparticles

The present study was conducted to fabricate the morphological variance of green synthesized silver nanoparticles (GSAgNPs) through scanning electron microscopy (SEM) and optical imaging. The green synthesis of AgNPs is an eco-friendly approach for obtaining high-density immobilized GSAgNPs on a matrix surface. High density Ag nanocomposites were deposited onto matrix surface through electrostatic interaction between substrate and nanoparticles. The GSAgNPs concentration on the matrix surface could be changed by varying the quantity of the nanoparticles. Ultraviolet visible (UV) spectroscopy, followed by zeta analysis, energy dispersive X-ray spectroscopy (EDX) and X-ray diffraction spectroscopy (XRD) were applied for GSAgNPs identification. GSAgNPs were morphologically fabricated through scanning electron microscopy (SEM) at various scales on functional matrix surfaces. The morphological diversity of the GSAgNPs was also evaluated via highly magnified optical micrographs, which revealed that the obtained micrographs exhibited a diversity of shape, (i.e., irregular, cylindrical, and spherical) and size, with a range of 6.39-15.15 mm in diameter. This work represents a significant step toward the potential application of immobilized GSAgNPs on various surfaces for catalytic activities and for developing nano-sheets, nano-films, and water repellent substances.
