AI Insight
This study reports the green synthesis of copper oxide nanoparticles (CuO NPs) using aqueous extract of Calendula officinalis as a reducing and stabilizing agent, offering a more environmentally friendly alternative to conventional chemical synthesis methods. The resulting nanoparticles were characterized using standard physicochemical techniques to confirm their structural and morphological properties. Toxicity assessments were conducted to evaluate the biological safety profile of the synthesized CuO NPs, examining their potential cytotoxic or antimicrobial effects.
Why it matters
Green synthesis approaches reduce the use of hazardous chemicals in nanomaterial production, making large-scale manufacturing safer and more sustainable. CuO nanoparticles have potential applications in antimicrobial coatings, drug delivery, and catalysis, and understanding their toxicity is essential before any biomedical or environmental deployment.
