Green Synthesis of Nano Silver Particles Using Some Selected Plant Species: Comparative Studies

Aminushehu Abubakar, Ibrahim Bala Salisu, Shiwani Chahal

Abstract :

Silver nanoparticles were synthesized using leaf extracts of three selected plants belonging to different family of assicaceae(Brassica nepus), meliacea (Azadhiractaindica) and asteracea (Stevia rebaudiana). Each of the three plants housed a large number of phytochemicals that are capable of reducing ionic silver to atomic silver. Nano silver particles were produced by mixing 90ml of 1mM aqueous solution of silver nitrate with 10ml of the extract in each case. Characterization was done by physical observation of colour change, UV–Vis spectroscopy and transmission electron microscopy (TEM). There were variations in colour changes which were attributed to the participating phytochemical presence in each of the plants. Size variations were also found with the average of 12.10nm, 20.30nm and 18.80 using the extracts from assica, neem and stevia respectively.
