Abstract The green synthesis of CuO nanoparticles was synthesized by Allium sativum extract. The powder X-ray diffraction pattern explained the high crystalline nature and the calculated crystallite size in 25−35 nm. The Fourier transform infrared spectrum described the CuO bonding nature. The UV visible analysis reported the surface Plasmon resonance band at 398 nm. The Photoluminescence spectrum denoted the red band emission in the visible region. The particle size analyzer displayed the CuO nanoparticles in a 20−40 nm range of size. The SEM images manifested the spherical, oval-shaped morphology of CuO nanoparticles. The EDAX spectrum and mapping proved the purity of CuO with Cu and O occurrence. The HRTEM images confirmed the crystalline nature formation of CuO nanoparticles. The phytochemical analysis listed the phytochemicals contributed for CuO nanoparticle synthesis via Allium sativum extract. The antimicrobial activity reported the efficient infection on bacteria as well as fungi. The antioxidant activity demonstrated the potential ability of free radical scavenging activity. The potential anti-inflammatory activity against egg albumin has obtained. The anti larvicidal activity showed the notable potential nature of affection on Anopheles subpictus mosquito larvae. At 21st century, CuO nanoparticles from environment friendly synthesis have special efficient applications in drugs, optics, batteries, gas sensors, catalysts, cosmetics, and semiconductor applications. Moreover, CuO nanoparticles have future applications in formulating the drug for human life-threatening diseases and various dangerous cancer treatments.
