Abstract
In the current study, an ecofriendly and economically very effective method for the biosynthesis of silver nanoparticles (AgNPs) using aqueous extract of Aloe vera leaves has been investigated. The synthesis of AgNPs was checked by the change of color of the solution from yellow to dark blue or black due to a phenomenon known as surface plasmon resonance. The ability of silver nanoparticles to get effected by various process parameters like volume of Aloe vera leaves extract, concentration of silver nitrate solution, and the total incubation time was checked. The analysis and characterization was done using UV-Visible spectroscopy and SEM-EDX. The SEM-EDX analysis confirmed the size, shape and formation of the silver nanoparticles. The best conditions needed for the synthesis of AgNPs using Aloe vera leaves extract was found to be 5mM concentration of silver nitrate solution using 15% volume of Aloe vera leaves extract and incubated for 10minutes under the sunlight.
