“…For the synthesis of nanoparticles, many physical and chemical methods are available which use toxic chemicals as a major constituent ( Kumar et al, 2013 , Suganya et al, 2017 , Ishwarya et al, 2017a , Iswarya et al, 2017b , Thaya et al, 2018 , Karthika et al, 2020 , Kiriyanthan et al, 2020 , Sebastiammal et al, 2020 ). So the need of the hour is to use greener, environmentally benign and eco-friendly routes for the synthesis of metallic nanoparticles ( Karthika et al, 2017 ).…”
