Magnetic nanoparticles have recently attained much interest due to the wide
distribution of their applications. The current work is concerned with the synthesis
of magnetic iron oxide nanoparticles using green and chemical methods.
Licorice extract has been used as the main factor for the production of green
synthesized magnetic nanoparticles (GSM), compared with the co-precipitation
method for the production of chemically synthesized magnetic nanoparticles
(CSM). Both scanning electron microscopy (SEM) and particle size analyzer
(PSA) proved the formation of the particles in the nanoscale with the range of
50–110 nm and 40–100 nm for GSM and CSM, respectively. Furthermore,
Energy-dispersive X-ray spectroscopy (EDX) indicated the existence of iron and
oxygen elements in both the samples and proved the formation of iron oxide
nanoparticles. Both types of nanoparticles were solely integrated with chitosan
for the formation of magnetic-dependent membranes followed by integrationdependent
characterization using SEM and Raman spectroscopy. The tensile
properties of the membranes showed higher elongation and strain properties of
chitosan/GSM membrane compared with plain chitosan or chitosan/CSM
membranes, which candidate it for mechanical-dependent applications. The
vibrating sample magnetism (VSM) properties showed that GSM nanoparticles
methanol electrochemical sensors with high sensitivity even at low concentrations
of methanol.are superparamagnetic. In addition, the GSM nanoparticles are applied as
