Featured Application: Greener synthesis and applications of Core-shell nanoparticles.Abstract: Among an array of hybrid nanoparticles, core-shell nanoparticles comprise of two or more materials, such as metals and biomolecules, wherein one of them forms the core at the center, while the other material/materials that were located around the central core develops a shell. Core-shell nanostructures are useful entities with high thermal and chemical stability, lower toxicity, greater solubility, and higher permeability to specific target cells. Plant or natural products-mediated synthesis of nanostructures refers to the use of plants or its extracts for the synthesis of nanostructures, an emerging field of sustainable nanotechnology. Various physiochemical and greener methods have been advanced for the synthesis of nanostructures, in contrast to conventional approaches that require the use of synthetic compounds for the assembly of nanostructures. Although several biological resources have been exploited for the synthesis of core-shell nanoparticles, but plant-based materials appear to be the ideal candidates for large-scale green synthesis of core-shell nanoparticles. This review summarizes the known strategies for the greener production of core-shell nanoparticles using plants extract or their derivatives and highlights their salient attributes, such as low costs, the lack of dependence on the use of any toxic materials, and the environmental friendliness for the sustainable assembly of stabile nanostructures.

“…[2,10] Moreover, the accumulation of the oxidation products of the analytes at the surface of the electrode leads to the electrode poisoning and results in the loss of reusability, selectivity and reproducibility. Fortunately, the use of chemically modified electrodes can overcome the mentioned problems and improve the determination of DA, AA, and UA, to distinguish the oxidation potentials of the three species and achieve the simultaneously detection, [8,11,12] which cannot be achieved by the optical or ECL method.…”

Intercalation lithium cobalt oxide (LCO) with the properties of insertion and de‐intercalation of Li+ was utilized to fabricate the sensitive dopamine (DA) sensor, which has excellent adsorption and catalytic behavior. LCO mixed with graphite powder (LCO−G) for individual and simultaneous determination of DA and uric acid (UA) achieved the low detection limits and the wide concentration ranges without the interference of ascorbic acid (AA). For individual detection, the linear responses of DA and UA were in the concentration ranges of 0.020–20 μM and 0.500–200 μM with the detection limits of 4.0 nM and 0.18 μM (s/n=3), respectively. For simultaneous detection with UA and AA by the change of the concentrations of DA, the linear response ranges were 0.050–20 μM with the detection limit of 7.9 nM (s/n=3). The LCO−G/GCE was further applied to the detection of DA in human serum to illustrate its potential of highly sensitive and selective electrochemical sensing.

In this article, we present a simple and efficient method to synthesize a magnetic NiFe2O4 nanocatalyst under hydrothermal conditions. Fourier transform infrared spectroscopy (FT‐IR), X‐ray diffraction (XRD), scanning electron microscopy (SEM), and energy dispersive X‐ray spectroscopy (EDX) analyses confirmed the synthesis of NiFe2O4 nanoparticles. These nanoparticles showed satisfactory catalytic activity for determination of norepinephrine (NE) in the presence of folic acid (FA) using cyclic voltammetry (CV) and differential pulse voltammetry (DPV) methods. Differential pulse voltammetry peak currents of NE increased linearly with their concentrations in the range of 1.0 × 10−7–5.0 × 10−4 M, and the detection limit for NE was 2.3 × 10−8 M, respectively. The modified electrode displayed strong function for resolving the overlapping voltammetric responses of NE and FA into two well‐defined voltammetric peaks. In the mixture containing NE and FA, the two compounds can well separate from each other with a potential difference of 510 mV between NE and FA, which was large enough to determine NE and FA individually and simultaneously. Additionally, the prepared electrochemical sensor demonstrated a practical feasibility for real sample determination.
