What is An advanced and Facile Synthesized Graphene/Magnetic Fe 3 O 4 Nanoparticles Platform for Subnanomolar Voltammetric Determination of Antipsychotic Olanzapine Drug in Human Plasma about?
Magnetite nanoparticles (Fe 3 O 4 NPs) hold a promising performance towards sensing applications. Fe 3 O 4 NPs were synthesized by economically viable method and characterized using different techniques. X-ray diffraction (XRD) pattern of Fe 3 O 4 NPs matched consistently with the database in JCPDS card (19-0629) for magnetite. Their average size was around 16 nm. The values of saturation magnetization and pH at point of zero charge (pHzpc) of the NPs were found to be 61.50 emu g -1 and 7.4, respectively. A novel magnetite-graphene nanocomposite (Fe 3 O 4 -GR) was then synthesized based on ex situ approach (in which pre-synthesized Fe 3 O 4 NPs were used to anchor the graphene nanosheets). Transmission electronic microscopy (TEM) and Scanning electronic microscopy (SEM) images indicate that GR nanosheets are decorated by Fe 3 O 4 NPs. Further, Fe 3 O 4 -GR nanocomposite modified carbon paste electrode (Fe 3 O 4 -GR/CPE) was fabricated. Its effective surface area and surface morphology were studied using cyclic voltammetry and SEM techniqes, respectively. Among Fe 3 O 4 -GR/CPE, GR/CPE and Fe 3 O 4 /CPE, the electrochemical properties of Fe 3 O 4 -GR nanocomposite were superior to t
