“…While the direct synthesis of CoNi-LDHs on conductive substrates using conductive nanotubes is advantageous by virtue of avoiding the insulative binder material, the advantages of the conductive nanotube/LDH core/shell nanostructures must be emphasized. Zhao et al improved the conductivity of a CoNi-LDH-based sensor via the in situ growth of the LDH on a conductive Cu foam (CuF) substrate modified with cobalt copper carbonate hydroxide (CCCH) nanorods as nucleation points [47]. The resulting CCCH/CoNi-LDH core/shell nanostructure possessed high surface area and conductivity for enhanced electrochemical glucose detection.…”

“…Ultrathin growths of NiFe-LDHs without exfoliating the gallery worked well for glucose detection [46]. In order to have a stronger link between the active material and the current collector, a nickel foam substrate was reacted with a cobalt precursor to prepare copper cobalt carbonate hydroxide (CCCH) [47]. The NiCo-LDHs grown on CCCH showed better efficiency in sensing glucose due to the higher conductivity of copper foam and the higher surface area of active material.…”

Layered double hydroxides (LDHs) have attracted considerable attention as promising materials for electrochemical and optical sensors owing to their excellent catalytic properties, facile synthesis strategies, highly tunable morphology, and versatile hosting ability. LDH-based electrochemical sensors are affordable alternatives to traditional precious-metal-based sensors, as LDHs can be synthesized from abundant inorganic precursors. LDH-modified probes can directly catalyze or host catalytic compounds that facilitate analyte redox reactions, detected as changes in the probe’s current, voltage, or resistance. The porous and lamellar structure of LDHs allows rapid analyte diffusion and abundant active sites for enhanced sensor sensitivity. LDHs can be composed of conductive materials such as reduced graphene oxide (rGO) or metal nanoparticles for improved catalytic activity and analyte selectivity. As optical sensors, LDHs provide a spacious, stable structure for synergistic guest–host interactions. LDHs can immobilize fluorophores, chemiluminescence reactants, and other spectroscopically active materials to reduce the aggregation and dissolution of the embedded sensor molecules, yielding enhanced optical responses and increased probe reusability. This review discusses standard LDH synthesis methods and overviews the different electrochemical and optical analysis techniques. Furthermore, the designs and modifications of exemplary LDHs and LDH composite materials are analyzed, focusing on the analytical performance of LDH-based sensors for key biomarkers and pollutants, including glucose, dopamine (DA), H2O2, metal ions, nitrogen-based toxins, and other organic compounds.

“…oxidation current peak for glucose at 0.50 V, which could be attributed to the conversion between Ni 2+ and Ni 3+ . 39 Furthermore, the CuCo 2 O 4 /CC electrode exhibits two electrocatalytic oxidation peaks for glucose at 0.38 and 0.57 V, which may be ascribed to the transition of Cu 2+ /Cu 3+ and Co 2+ /Co 3+ , respectively. 57 Figure 5c shows the CVs of the CuCo 2 O 4 /NiO NNAs/CC with different concentrations of glucose in 0.15 M NaOH at a scan rate of 50 mV s −1 .…”

“…36−38 Therefore, there is a demand to develop efficient, highly sensitive, and low-cost sensors for monitoring blood glucose. 39 However, most of the traditional glucose sensors use natural enzymes as receptors, 40 which greatly restrict the practical application of the sensors due to the shortcomings of the natural enzymes including easy activity loss, high cost, complex fixation process, and instability. 41−43 Herein, we have hydrothermally synthesized hierarchical CuCo 2 O 4 /NiO core−shell nanoneedle arrays (CuCo 2 O 4 /NiO NNAs) on a CC, which is directly used as a flexible electrode for glucose detection.…”

Transition-metal oxide nanocomposites with a core−shell structure exhibit excellent catalytic performance because of their large surface area and the synergetic effect resulting from their special structures. In this work, a two-step hydrothermal method was used to synthesize hierarchical CuCo 2 O 4 /NiO core−shell nanoneedle arrays (NNAs) on conductive carbon cloth (CC) as a self-supported electrode. The morphology and structure of CuCo 2 O 4 /NiO NNAs/CC were studied in detail by various microscopes and spectroscopes. The synthesized CuCo 2 O 4 /NiO NNAs exhibited excellent electrocatalytic properties toward glucose oxidation due to the hierarchical core−shell structure and the resulting synergetic effect. Therefore, CuCo 2 O 4 /NiO NNAs/CC showed excellent characteristics for glucose determination with high sensitivity (4140 μA mM −1 cm −2 ), broad linear range (0.5−6000 μM), and outstanding selectivity and stability. Moreover, the proposed sensor was evaluated to determine glucose in human serum samples with satisfactory recovery, indicating its potential practical application in quantitative analysis of blood glucose levels.

The surfaces of thin composite electrochromic Ni(OH)2-polyvinyl alcohol films, deposited by the cathodic template method on FTO glass substrates, were proposed to be processed using laser radiation. The processing of these films was carried out in a colored state with a laser beam of a semiconductor emitter with a wavelength of 650 nm (red) with a pulse duration of 3,000 μs, the beam diameter was about 40 μm. The energy at a single point was 37.5 J/cm2. The result was a film with microholes of about 80 μm. The transparent areas of the surface did not exhibit electrochromic properties, which indicated the absence of the original electrochromic coating. The study of the properties of the laser-processed film following a certain pattern showed that the characteristics of composite Ni(OH)2-polyvinyl alcohol coatings had changed significantly. On the one hand, the coloration depth of the films decreased by several percent, on the other hand, the specific electrochemical characteristics increased significantly. The study also showed that laser processing did not lead to significant changes in the main properties of the transparent electrically conductive layer – color and resistance. Before and after laser processing, the surface resistance of FTO glasses was 12.1±0.9 and 14.4±1.2 Ohm/sq., respectively. In addition, it was found that the processing of Ni(OH)2-polyvinyl alcohol films improved the adhesion of the latter to the surface of FTO glass. Based on the data obtained, a selective method was proposed for modifying thin colored films deposited on transparent conductive oxides (FTO, ITO, AZO) by visible laser radiation. This approach to changing the properties of films can be useful for areas related to the development of sensors, microelectronics, solar cells, small-sized current sources, electrodes with high efficiency, etc.
