“…18−21 Spinel ferrites are represented by the general formula MFe 2 O 4 , where M is a metal or a group of metallic elements with two different valences. 22 In particular, the MFe 2 O 4 (M = Mn, Fe, Co, Ni) ferrites with spinel structure exhibit interesting magnetic, magnetoresistive, and magnetooptical properties that were potentially useful for a broad range of applications. Among spinel ferrites, nickel ferrite (NiFe 2 O 4 ) was known as a soft magnetic material and was the most important spinel ferrite.…”

Application of porous magnetic materials for detoxification of pollutants from aqueous solutions has attracted great attention in recent years because of their ease of separation and enhanced efficiency. In this light, a three-dimensional (3D) porous NiFe 2 O 4 adsorbent (PNA) having significant magnetic properties was synthesized and employed in detoxification of Pb(II) contaminated aqueous solution. The PNA was obtained by a sol−gel process using chitosan as precursor and was fully characterized by using FTIR, XRD, SEM, and EDAX analytical techniques. The surface morphology obtained from the SEM images of the PNA clearly exhibited the three-dimensional porous structure; pores were well interconnected. The kinetic mechanism was best described by pseudo-second-order and double-exponential models. The equilibrium state sorption data was best fitted to the Langmuir and Sips isotherm models. The studies clearly demonstrated that the PNA could be an efficient material for treatment of Pb(II) contaminated wastewaters.

“…For the synthesis of mixed metal oxide nanoparticles, various methods such as, electrochemical [29], inverse microemulsion [30], hydrothermal [31], solvothermal [32], thermal decomposition [33], electrospinning [34], microwave-assisted [35], high energy mechanical ball milling [36], thermal evaporation [37] and sol-gel [38] processes have been employed. However, most of these approaches generally require high reaction temperature, tedious procedures, high-energy, long reaction time, expensive equipments, and harmful organic reagents or surfactants, which might further hinder their application.…”

“…Nickel ferrite (NiFe 2 O 4 ) is also one of the most important materials that can be used for biosensors applications due to its notable electrocatalytic property [7]. Conventional methods for NiFe 2 O 4 preparation [8], such as mechanosynthesis [9], sol-gel processing [10], solvothermal processes [11], spray pyrolysis [12], hydrothermal processes [13] and microwave assisted combustion methods [14], are generally quite difficult to control its size and morphology [15]. Therefore coprecipitation is an appealing technique due to its advantages of homogeneity, small particle size, low temperature preparation and simple process [16].…”

An effective, stable enzymatic glucose biosensor was fabricated on a glassy carbon electrode (GCE) surface using simple multicomposite materials (MCM): a solution of prepared poly(diallyldimethylammonium chloride)‐capped gold nanoparticles‐nickel ferrite particles‐carbon nanotubes‐chitosan (PDDA‐AuNPs‐NiFe2O4‐CNTs‐CHIT), electropolymerization of poly(o‐phenylenediamine) (PoPD) and immobilization of glucose oxidase (GOx). Biocompatibility and synergy of the MCM enhanced the immobilization and the reaction of GOx and as well as the electron transfer from an oxidation reaction of hydrogen peroxide in the system. The NiFe2O4 was synthesized by co‐precipitation and calcined at 700 °C. Characterization was carried out by field emission scanning electron microscopy (FE‐SEM), energy‐dispersive X‐ray spectroscopy (EDX), Fourier transform infrared spectroscopy (FTIR) and X‐ray diffraction (XRD) which presented both tetrahedral and octahedral metal stretching with a cubic NiFe2O4 crystal phase. The GOx/PoPD/MCM/GCE yielded a 0.77 s−1 charge transfer rate constant (Ks), a 2.28×10−6 cm2 s−1 diffusion coefficient value (D), a 0.21 mm2 electroactive surface area (Ae) and a 1.93×10−8 mol cm−2 surface concentration (γ ) as determined by cyclic voltammetry. The modified electrode showed a durable operation time (n=97, more than 50 % I), repeatability (%RSD=0.38, n=10), reproducibility (%RSD=1.60, n=10), high sensitivity (853.07 μA mM−1 cm−2), selectivity without effects of electroactive species (aspirin, uric acid, caffeine, cholesterol, ascorbic acid and dopamine) and two linear ranges from 0.5 to 10 μM (R2=0.998) and 10 to 15,000 μM (R2=0.991) with a low detection limit (0.35 μM, S/N=3). Its Michaelis‐Menten constant (Km) was calculated as 93.51 μM with 46.30 μA maximum current (Imax). This proposed simple method was successfully applied for glucose determination in human blood samples.
