“…There are number of reports on the synthesis of core shell BNP Au‐Fe for catalytic applications . Usually, the synthesis approaches for these BNP Au‐Fe require multi‐step processes including high‐end instruments, complex filtration, sequential synthesis, and time taking protocols . Involvement of multi‐step process, lengthy reaction time, expensive instruments, limit the quick synthesis of such BNP Au‐Fe and their composites.…”

We report for the first time a microwave assisted, one pot, direct, and facile synthesis of monodispersed iron‐gold bimetallic nanoparticles (BNPAu‐Fe) using glucose as a reducing agent in merely 90 s. The as such synthesized BNPAu‐Fe were thoroughly characterized using UV‐Vis, XRD, TEM, EDX, elemental mapping, and raman spectroscopy. These BNPAu‐Fe were further impregnated with reduced graphene oxide (rGO) and coated onto glassy carbon electrode (GCE) to develop a sensor probe for label free electrochemical detection of acetaminophen, which is considered to be a most potent biomarker related to non‐alcoholic fatty liver disease. The sensor probe was systematically characterized by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The BNPAu‐Fe‐rGO nanocomposite matrix showed the sensing of acetaminophen with a wide dynamic range between 50 and 800 nM with detection limit (DL) of 0.14 nM (±0.05) nM (RSD<4.12 %) that was lower compared to previously reported acetaminophen sensors. To show the practical application of the sensor probe, acetaminophen was detected in human urine samples, which showed the percentage recovery between 86.65 % and 91.32 %. To the best of our knowledge, this is the first report where BNPAu‐Fe impregnated rGO was used to detect acetaminophen. Interferences due to various molecules such as glucose, serum albumin, glycine, glutamic acid, alanine, citric acid, and ascorbic acid were tested individually and in mixed sample. Long‐term stability of sensor probe was examined which was found to be stable up to 12 weeks. The sensor fabricated using BNPAu‐Fe‐rGO nanocomposite has many attractive features such as; simplicity, rapidity, and label free detection, hence it could be a method of choice for acetaminophen detection in clinical settings.

This study shows the influence of selected nonstandard surfactants on the growth and properties of magnetite nanoparticles. Particles were obtained using thermally decomposed iron (III) acetylacetonate in an organic environment. For synthesis, three different concentrations (4, 8, and 16 mmol) of tested surfactants were used. Five types of each long-chain carboxylic acid and amines were selected for stabilization of nanoparticles. Nanoparticles were characterized by X-ray diffraction, transmission electron microscopy, and infrared spectroscopy. Magnetic properties of the nanoparticles were tested by conventional room temperature Mössbauer spectroscopy with and without external magnetic field. TEM images clearly showed that application of tertiary amines causes the nanoparticles to form nanoflowers, in contrast to other compounds, which do not show such growth. Influence of surfactant amount on growth regime depends on the nature of the substances. Mössbauer spectroscopy confirms differences in magnetic core composition as a result of the surfactant amount present in synthetic procedure.

“…28 Furthermore, Au modification can also bring some other benefits, such as protecting the stability of Fe3O4 under harsh conditions, which is convenient for surface chemical modification of composite materials. 29,30 In our previous study, we had synthesized a variety of functionalized Fe3O4@Au nanoparticles, which were successfully applied in molecular imprinting technology as a carrier with good results. [31][32][33] The conductivity of nanoparticles can effectively promote the electron transfer on the surface of the electrode, which provided feasibility for electrochemical sensing based on molecularly imprinted materials.…”

A study of an electrochemical sensor based on bovine hemoglobin (BHb) imprinted magnetic nanoparticles (MIPs) was investigated. First, BHb MIPs were successfully synthesized with magnetic Fe3O4@Au nanoparticles as carrier by surface modification of mercapto propionic acid for introducing carboxyl groups, combined with dopamine as the functional monomer and BHb as the template protein. Then, the MIPs were modified to the surface of a glassy carbon electrode (GCE) for electrochemical analysis by using cyclic voltammetry in the potassium ferricyanide solution. Results show that there was a good dynamic response between electrochemical signals and the adsorption amount of protein in the range of 0.05 to 0.5 mg mL -1 . Results show that the sensor exhibits a significant specific recognition toward the template protein via selective test and can be used for analysis of serum samples. The synthesized MIPs are suitable for the removal and enrichment of template protein in proteomics. At the same time, the proposed electrochemical sensor can be used for recognition of BHb.
