Abstract
Iron-oxide nanoparticles are synthesized by the Green Chemistry method and using Gooseberry leaves extract as reducing agent. The characterization of the nanoparticles was carried by the common tools which include UV–Vis, SEM, EDX, XRD, FTIR and CV. UV–Vis confirms the formation of iron oxide nanoparticles. SEM verifies the spherical morphology of the nanoparticles. Elemental composition was determined by the EDX. XRD peaks details the spinal state crystal structure of the as-synthesized iron-oxide nanoparticles. CV results confirm the electrochemical nature of the iron-oxide nanoparticles useful for biosensing. Finally Bioassay tests reveal that these nanoparticles can be potent candidate to be used as biosensors.
