Green Synthesis of Copper based Nanostructures using Tannic Acid and Testing of their Antibacterial Properties

Co-authors ROTKOVÁ Jana

In this study, copper-based nanostructures were prepared by the so-called "green synthesis" through a redox reaction between tannic acid and cupric ions of CuSO4.5 H2O in water without adjustment of pH. Tannic acid is hydrolysed tannin present in the leaves and bark of many trees and plants and like as an antioxidant has a relatively strong reducing properties. Resulting colloidal solution had a large surface area with a nanoporous structure and its antibacterial properties have been studied with the use of Gram-negative bacteria Escherichia coli.
