Eco-friendly synthesis of silver nanoparticles using Umbrella plant, and evaluation of their photocatalytic and antibacterial activities

The use of plants in nanosynthesis has potentiated the application of most greeneries in this field of study. The aqueous extract of Umbrella plant and different concentrations (1 mM, 2 mM and 5 mM) of AgNO3 were utilized in the preparation of silver nanoparticles (AgNPs). Two volume ratios, 1:5 and 1:10, of the substrate to the precursor were used, and the rate of formation of the AgNPs was monitored using UV-vis spectroscopy. The nanoparticles...
