“…Lately, plant and plant extracts [22,23], yeast [23], fungi [24], bacteria [25] and mushrooms [26] have been used to obtain Ag nanoparticles for nontoxic production [27].…”

Green-nanochemistry for safe environment: bio-friendly synthesis of fluorescent monometallic (Ag and Au) and bimetallic (Ag/Au alloy) nanoparticles having pesticide sensing activity

“…Formation of toxic by-product is another problem associated with these methods [4][5][6]. On the other hand, in the case of physical method of synthesis of metal NPs, high temperature and pressure are required leading to the vast consumption of energy [7]. Therefore, researchers working in the field of nanochemistry are in an incessant quest for the new and alternative synthetic routes which are more dexterous, economic, hazard free, and environmentally viable and can yield metal NPs with desirable structural activities.…”

Water Extract of Piper Nigrum Seed Assisted Synthesis of Silver Nanoparticles and Reduction of Various Nitro Compounds by NaBH4 in the Presence of AgNPs as a Catalyst

“…Previous studies reveal that a strong reducing agent such as sodium borohydride resulted in small particle size that was somewhat mono-dispersed and the generation of larger particle was difficult to control in this method. On the other hand, weaker reducing agents resulted in decreased rate of reduction and particle size distribution over a broad range [3][4][5] .…”
