More salt is used in green synthesis as compared to chemical one. Though chemical reducing agents are replaced by environmental friendly one but salts themselves are more deleterious to environment than the chemical reducing agents. Besides how can we relate the use of nanoparticles against clinical pathogens to the domain of Environmental Science.
Are you equating 'green synthesis' with growing plants? Are nanoparticles being produced from plants? Ho are they used against pathogens?

How is the precursor of green synthesis eco friendly. For example; if I am preparing Cu NPs using copper sulphate that is itself very toxic. Though I am using an environmental friendly reducing agent the form of tea extract, fruit peel extract etc. Where would metal salt go ultimately and how are as synthesized NPs biodegradable ?
