Abstract:
Eco-synthesis represents a green strategy for obtaining nanoparticles and is of particular interest because it is an environmentally friendly, sustainable, extremely fast, and efficient technological process which involves the use of natural resources. In this context the current paper presents the eco-synthesis of CuO NPs using an aqueous extract of Menta piperita L. In a first stage, the aqueous extract from the Menta piperita L. species was obtained by applying a solid- liquid extraction and then was characterized from the point of view of the total content of polyphenols (TPC) by spectrometric Folin-Ciocalteu method and the antioxidant activity was determined by the DPPH(2,2-diphenyl-1-picrylhydrazyl) method. Subsequently, copper oxide particles were eco-synthesized and characterized by UV-Vis absorption spectroscopy. Particle size distribution of the phytosynthesized CuO NPs have been evaluated by dynamic light scattering, and their physical stability was estimated by zeta potential measurements.
