Author: Aminu Shehu Abubakar, Ibrahim Bala Salisu, Shiwani Chahal, Geetika Sahni, Ramesh Namdeo Pudake
The synthesis of nano particles using the bio system is referred to as Green Synthesis, as it a cost-effective, energy-efficient and easy method. Here we have used the green approach for the synthesis of silver nanoparticles (AgNPs) using Black carrots as the source phytochemicals for reducing and capping agent for the reduction of silver ions to silver atoms and stabilization of the particles. The black carrot extract was added into 1mM silver nitrate solution and the formation of AgNPs was primarily detected by the change of colour to reddish-brown. The nano particles were further characterized by using UV-Vis spectroscopy and Transmission Electron Microscopy (TEM) analysis. The maximum Plasmon absorbance peak of 413 nm was obtained, and nanoparticles sizes ranges from 4.32 nm to 17.65 nm with an average diameter of 9.46 nm. Around 88 % of the particles depicted by the TEM image fall within the range 4-12 nm. The method used here confirms the synthesis of AgNps by using the root extracts of black carrots and, it is simple, eco-friendly and economical for large-scale production of AgNps.
