“…When compared to the successive casting in the two steps of carbon nanomaterial followed by NPs [21], these novel composites afford not only a "real" nanoparticulated substrate but also an increased electroactive area due to the nature of the carbon nanomaterials employed. Taking this advantage, platinum [25], silver [26], nickel [27], and gold [28] were used in combination with carbon nanotubes [25], nanoporous carbon [27], and reduced graphene oxide [26] or graphene oxide [28] to obtain novel composite sensing devices with improved catalytic performance.…”

Recent progress in the field of electroanalysis with metal nanoparticle (NP)-based screen-printed electrodes (SPEs) is discussed, focusing on the methods employed to perform the electrode surface functionalization, and the final application achieved with different types of metallic NPs. The ink mixing approach, electrochemical deposition, and drop casting are the usual methodologies used for SPEs’ modification purposes to obtain nanoparticulated sensing phases with suitable tailor-made functionalities. Among these, applications on inorganic and organic molecule sensing with several NPs of transition metals, bimetallic alloys, and metal oxides should be highlighted.

Nickel/carbon composites (Ni−C) have been synthesized by a pyrolysis treatment carried out at the temperature of 675 °C, of NiO incorporated into a pyrogallol‐formaldehyde organic wet gel. Structural and morphological characterizations of the Ni−C samples were performed by XRD and SEM analysis, respectively. Electrochemical non‐enzymatic glucose sensors were fabricated modifying the working electrode surface of screen printed carbon electrodes. Cyclic voltammetry and amperometric tests were performed in order to investigate the electrocatalytic activity of differently Ni loaded carbon towards the oxidation of glucose in alkaline 0.1 M KOH solution. The sensor based on 30 % Ni/carbon showed the best sensing performance towards glucose monitoring with a sensitivity of 670 μA/mM cm−1 in the a liner range from 20 to 500 μM, and a detection limit lower than 8 μM at S/N=3.

“…In fact, these nanoparticles characterized by a high surface/volume ratio, low toxicity, high chemical stability, and quick electron transfer capabilities, which improve the performance of nanomaterials when applied as biomimetic membranes to detect proteins and maintain their activity [16,17]. Nevertheless, the incorporation of inorganic nanoparticles into a porous carbon matrix has led the way for a new class of materials with unique electrical and optical properties, making them appealing for use in disciplines such as optoelectronics [18], sensor design [19,20], and catalysis [21]. The interfacial interplay between the inorganic nanoparticles and the PF porous matrix is crucial in determining the hybrid nanocomposites' various electrical characteristics.…”

In this work, we report the synthesis of different hybrid nanocomposites by sol-gel method. Therefore, we used picric acid as a catalyst to incorporate the nanopowder oxides of nickel (NiO), copper (CuO) and manganese (MnO) in the porous carbon matrix based on pyrogallol and formaldehyde (PF). After a drying and heat treatment for two hours at 650 °C pyrolysis temperature, the obtained materials have been characterized by different structural and electrical techniques. The X-ray diffraction (XRD) spectra show that the incorporation of inorganic nanoparticles improved the crystallization of different nanocomposites with the existance of a graphite phase. The transmission electron microscopy (TEM) images reveal that the graphite nanoparticles size depends to the incorporated inorganic oxide. From the electrical studies, we notice that electrical conduction is linked to the presence of graphite nanoparticles. The variation of the electrical conductivity and the relaxation time with the measurement temperature, ranging between 80 and 300 K, explain the effect of the hopping conduction mechanism in these nanocomposites.
