“…(Punjabi et al, 2018 ; Arun et al, 2019 ; Guilger-Casagrande and de Lima, 2019 ; de Oca-Vásquez et al, 2020 ). NPs are usually synthesized with distinct physical, chemical, and biological methods, but are inconvenienced by their cost, slow process as well as generation of waste causing environmental pollution and biotic harmfulness (Wang et al, 2016 ; Unni et al, 2017 ; Gahlawat and Choudhury, 2019 ; Hamida et al, 2020 ; Tortella et al, 2020 ). The physical methods utilize costly equipments and produce unstable larger nanoparticles, while hydrazine and sodium borohydride like hazardous materials are used as reducing agents in the chemical approaches (Mohanta et al, 2017 ; Chandraker et al, 2019a ).…”
