Abstract
Nanotechnology is presently one of the most dynamic disciplines of research in contemporary material science. Currently, a large number of physical, chemical, biological, and hybrid methods are available to synthesize different types of nanoparticles. Physical and chemical methods have been using high radiation and highly concentrated reductants and stabilizing agents that are harmful to environmental and to human health. Hence, biological synthesis of nanoparticles is a single step bio reduction method and less energy is used to synthesize eco-friendly NPs. The present study included the chemical reduction of copper acetate through glucose and testing for their antimicrobial activity. The aqueous copper acetate mixed with the reducing agent as glucose results in the synthesis of copper oxide nanoparticles proved by colour changes. Absorption spectrum of the incubated solution at different wavelengths ranging from 300 to 800 nm revealed a peak at 540 nm. High resolution scanning electron microscopic (SEM) image of Copper oxide nanoparticles (CuONPs). Spherical shaped CuNPs size at 42.28 nm. Bacillus subtilis bacteria strain was qualitatively assessed by the presence of inhibition zones (30µl: 5.50±0.38, 60µl: 7.50±0.52 and Standard 8.50±0.59). It is confirmed that copper oxide nanoparticles are capable of rendering high antibacterial efficacy and hence has a great potential in the preparation of drugs used against bacterial diseases. Applications of CuO nanoparticles based on these findings may lead to valuable discoveries in various fields such as medical devices and antimicrobial systems.
