Green Synthesis, Optimization and Characterization of Carrot Extract Silver Nanoparticles

Silver nanoparticles (AgNPs) are currently being used in the field of nanomedicine. Carrots are plants with phytochemicals that act as reducing and capping agents for nanoparticles. The use of plant extracts is considered a safe, non-toxic, and effective therapeutic option for various diseases. The aim of this study was to synthesis, optimize, and characterize silver nanoparticles using carrot extract. The green synthesis of carrot extract AgNPs was carried out by mixing ethanol extract of carrot with silver nitrate (AgNO3) at concentrations ranging from 1 to 3 mM and pH 6 - 8. Carrot extract silver nanoparticles (CE-AgNPs) was characterized using UV-Vis spectrophotometry, particle size analysis (PSA), Field Emission Scanning Electron Microscopy (FE-SEM), and X-ray diffractometry (XRD). The results showed that the optimal synthesis of carrot extract silver nanoparticles is done using AgNO3 at 1 mM concentration, and pH 7 which produced the smallest particle size. FE-SEM indicated the formation of spherical silver nanoparticles. XRD analysis indicated that the nanoparticles contain silver components. In conclusion, the conditions for carrot extract silver nanoparticles production can affect the particle size and morphology of the nanoparticles.
