The green synthesis aligns closely with chemical synthesis in terms of its principle, but avoids the use of hazardous toxic chemicals making it safer option . The primary motivation behind green synthesis is to minimize the adverse effects of traditional chemical synthesis that often involves use of harmful chemical reducing agents such as NaBH4, N,N-DMF and hydrazine derivatives . The green synthesis synthesizes AgNPs by reducing silver ions (Ag + ) to metallic silver (Ag) by using biological species or bio-based compounds . This process is also known as biological synthesis as the biobased compounds are often derived from microorganisms or plant extracts, which acts as reducing agent, replacing conventionally used toxic reducing agents . While the biological synthesis plays a main role in green synthesis, it is not completely restricted to biological methods, there are several physical methods such as laser irradiation , microwave irradiation [100,101], ionizing radiation and pulse radiolysis have also been employed to synthesize AgNPs without the use of chemical reducing agents like hydrazine and NaBH4 . However, these methods consume a huge amount of energy, which pose a challenge in terms of their cost effectivity and sustainability. Green synthesis presents itself as an alternative to conventional chemical and physical methods . This is because while chemical synthesis often involves the use of toxic solvent and reducing agents and physical methods require sustainable energy input, the green synthesis strikes a balance by synthesizing AgNPs using natural reducing agents and energy efficient techniques , thus making it ideal for mass production [95] and more economically feasible .
