“…Roots, shoots, flowers, seeds, fruits, bark, stems, and leaves act as different sources of biomass and secondary metabolites such as flavonoids, alkaloids, saponins, steroids, and tannins act as reducing and stabilizing agents (Abdel-Aziz et al, 2014). Plant extracts of Lemna minor, Parthenium hysterophorus, Satureja sahendica Bornm, and Carissa spinarum L. have been recently employed to synthesize ZnONPs (Del Buono et al, 2021;Umavathi et al, 2021;Chegini et al, 2022;Saka et al, 2022). Furthermore, agro wastes like coconut shell, red peanut skin extract, banana peel, and bagasse extract are being used to prepare a variety of metallic nanoparticles (Sinsinwar et al, 2018;Pan et al, 2020;Ruangtong et al, 2020;Ishak et al, 2021).…”
