Abstract
This research investigates the potential of various medicinal plant materials from the north western region (Rohtak, Haryana) for the biosynthesis of copper nanoparticles, as well as the identification of natural reducing, capping, and stabilizing agents present in these plants. The green synthesis approach presents a viable alternative to traditional methods, supporting sustainable development by minimizing environmental impact and energy consumption while ensuring compatibility with biological systems. The different medicinal plants were Ricinus communis, Citrus aurantium, Syzygium cumini, Calotropis procera, and Hibiscus rosa sinensis which were used for the synthesis of copper nanoparticles. Copper Sulfate (CuSO4), known for its anti-inflammatory properties, was utilized in this study. The UV Spectrophotometer analysis revealed peaks at 240 nm, 220 nm, 260 nm, 290 nm, and 270 nm within the 200 nm to 900 nm range, confirming the formation of nanoparticles. The advanced imaging capabilities of Scanning Electron Microscopy (SEM) facilitated accurate visualization of particle morphology, surface characteristics, and size measurements at the nanoscale. The analysis indicated an average particle diameter of 18.8 nm, accompanied by a narrow size distribution that reflects well-controlled synthesis conditions. Among the plants examined, Syzygium cumini (Jamun), belonging to the Myrtle family, exhibited the highest yield of copper nanoparticles. This study aims to assess a variety of plant species to determine the most suitable candidates for large-scale nanoparticle production via green synthesis, ultimately advancing sustainable nanotechnology.
