“…45,46 Later, XPS survey spectrum analysis in Figure S11a also shows the presence of all the expected elements like Ni, Co, V, S, O, and C. The high-resolution Ni 2p XPS spectrum (Figure S11b) shows the +3 and +2 oxidation states of the Ni 2p orbital with their respective binding energies values of 855.67 and 854.10 eV after 1000 CV cycles, which is well in accordance with the Raman analysis. 47 Figure S11c confirms the +3 and +2 oxidation states of the Co 2p orbital with the corresponding binding energy values of 779.16 and 780.88 eV, respectively. 48 These HR-TEM, Raman, and XPS analyses results suggest the highly stable nature of the CoS@NiV-LDH heterostructure even after a harsh anodic potential sweep for 1000 cycles.…”

Rational design and fabrication of electrocatalysts with outstanding performances and long-term durabilities are highly challenging for overall water-splitting reactions. Herein, interfacially engineered CoS@NiV-LDH heterostructures are fabricated by a simple top-down approach and used as bifunctional electrocatalysts for overall water splitting. Experimental results proved that the creation of an interface between pristine CoS and NiV-LDH can optimize the electronic structure of the active sites by transferring electrons from the NiV-LDH site to CoS, which boosts the formation of the NiOOH active phase, enhancing the catalytic performance in a 1 M KOH solution. While coupled with the heterostructure CoS@NiV-LDH as the anode and cathode, it demands a cell voltage of just 1.57 V to attain a current density of 10 mA cm–2 with remarkable stability for 70 h. Density functional theory (DFT) calculations reveal improved catalytic activity toward the oxygen evolution reaction (OER) for CoS@NiV-LDH with a lower energy barrier originating from the charge transfer-induced synergistic mechanism at the CoS and NiV-LDH interface. Moreover, the observed downshift of the d-band center for the CoS@NiV-LDH heterostructure explains their enhanced performance toward the hydrogen evolution reaction (HER), facilitating the H* adsorption/desorption process.

“…Figure d shows that the oxidation current increased continuously as the glucose concentration increased from 0.05 to 15 mM, while the potential shifted toward more positive values. Thus, the electrode reaction can be summarized as follows where eq represents the electrochemical oxidation of Ni 0.33 Co 0.67 (OH) 2 and eq represents the heterogeneous catalytic oxidation of glucose on the electrode surface.…”

Owing to their high catalytic activity, transition metal hydroxides are promising electrocatalysts for non-enzymatic glucose sensors. The hydroxyl functionalities in Co 1−x Ni x hydroxide/mixed anionic hydroxides play a vital role in their electrochemical activation via conversion to an oxyhydroxide catalyst and thus impact their sensitivity to small molecule (glucose) oxidation. Herein, we report the rational synthesis of M 2 (OH) 4−n (A n− ) compositions (0 > n ≤ 2) with hydroxide (OH)rich and OH-deficient phases, viz., CoNi-hydroxide nitrate (CoNi-HN) and CoNi-hydroxide carbonate (CoNi-HC), by using different solvents of ethanol and water, under solvo/hydrothermal conditions, respectively. The OH-rich CoNi-HN phase exhibited enhanced pre-activation efficiency, which accelerated the glucose oxidation kinetics, and beneficial morphological features (flowerlike structures with interconnected nanosheets). The OH-rich CoNi-HN catalyst, which is the first report for a glucose sensor, exhibited superior sensing property with a high sensitivity of ∼136 μA mM −1 cm −2 . The structure−(sensing) property relationship was analyzed in detail by tailoring the morphology to form an OH-rich graphene oxide (GO) hybrid. The CoNi-HN/GO hybrid exhibited improved glucose oxidation, delivering a wide glucose-sensing range, with a sensitivity of ∼268 μA mM −1 cm −2 , a low detection limit of 28.5 μM (S/N = 3), and good selectivity. The excellent sensitivity of this hybrid was attributed to the synergism between the OH-rich CoNi-HN phase and the OH-rich interfaces between GO and CoNi-HN, as well as a unique flower-like morphology with interconnected nanosheets. Insights into the critical role of hydroxyl groups in the electrocatalytic performance of transition-metal-based catalysts have been emphasized in this work.

In modern society, the incidence of cancer, inflammatory diseases, nervous system diseases, metabolic diseases, and cardiovascular diseases is on the rise. These diseases not only cause physical and mental suffering for patients, but also place an enormous burden on society. Early, non-invasive diagnosis of these diseases can reduce the physical and mental pain of patients and social stress. There is an urgent need for advanced materials and methods for non-invasive disease marker detection, large-scale disease screening, and early diagnosis. Biomimetic medical materials are synthetic materials designed to be biocompatible or biodegradable, then developed for use in the medical industry. In recent years, with the development of nanotechnology, a variety of biomimetic medical materials with advanced properties have been introduced. Biomimetic nanomaterials have made great progress in biosensing, bioimaging, and other fields. The latest advance of biomimetic nanomaterials in disease diagnosis has attracted tremendous interest. However, the application of biomimetic nanomaterials in disease diagnosis has not been reviewed. This review particularly focuses on the potential of biomimetic nanomaterials in non-invasive disease marker detection and disease diagnosis. The first part focuses on the properties and characteristics of different kinds of advanced biomimetic nanomaterials. In the second part, the recent cutting-edge methods using biosensors and bioimaging based on biomimetic nanomaterials for non-invasive disease diagnosis are reviewed. In addition, the existing problems and future development of biomimetic nanomaterials is briefly described in the third part. The application of biomimetic nanomaterials would provide a novel and promising diagnostic method for non-invasive disease marker detection, large-scale clinical screening, and diagnosis, promoting the exploitation of devices with better detection performance and the development of global clinical public health.
