“…Morphological characteristics of the synthesized Cu-based metal-organic nanoparticles (Cu-BTC NPs) and Cu-BTC/GO nanocomposites synthesized from solvosonication precursor solutions containing 0.005 (NC-1), 0.05 (NC-2), 0.1 (NC-3) and 0.15 mg/mL (NC-4) GO nanosheets were studied using FESEM images (Figure 3). Cu-BTC NPs synthesized via the solvosonication process presented a semi-spherical nanoparticle-form morphology, similar to the morphology of Cu-BTC metal-organic framework (MOF) synthesized by the hydrothermal process using DMF [28], and with ultrasound irradiation under solid-state conditions [29]. With the incorporation of GO nanosheets, Cu-BTC crystals formed on the surface of GO nanosheets, and a shift in the geometry of Cu-BTC NPs was observed.…”

Cu-based nanostructures are a well-known class of antibacterial nanomaterials with broad antibacterial properties. In this study, a facile and one-pot solvosonication process is introduced to synthesize Cu-BTC/graphene oxide nanocomposites with controlled morphological and structural properties. The size range of synthesized Cu-BTC nanoparticles is controlled through the synthesis process by adjusting the content of graphene oxide nanosheets in the synthesis precursor solution. A wide range of sizes and morphologies are achieved via this strategy and the size range of Cu-BTC nanoparticles from 30-40 nm to 15-20 nm are obtained by increasing the content of graphene oxide in the precursor solution from 0.005 to 0.15 mg/ml. We believe an increase in the number of available sites on the basal plane of graphene oxide for the nucleation of Cu-BTC nanocrystals is the main reason for the smaller size range of Cu-BTC nanoparticles with higher concentrations of graphene oxide in the precursor solution.Moreover, the antibacterial activities of the Cu-BTC/graphene oxide nanocomposites are also

“…This improved performance can be attributed to the existence of abundant channels into the composites, which improved both the adsorption and diffusion of glucose on the catalytic sites. A variety of other MO's nanocomposites derived from MOF [ 112,113,122–131,114,132–141,115,142–145,116–121 ] were developed for glucose sensing and Table 3 summarized their composition and relevant analytical performance.…”

Assessment of glucose concentration is important in the diagnosis and treatment of diabetes. Since the introduction of enzymatic glucose biosensors, scientific and technological advances in nanomaterials have led to the development of new generations of glucose sensors. This field has witnessed major developments over the last decade, as the novel nanomaterials are capable of efficiently catalyzing glucose directly (i.e., act as artificial enzymes, therefore defined nanozymes) or to entrap enzymes that are able to oxidize glucose. Among other nanomaterials, metal-organic frameworks (MOFs) have recently provided a tremendous basis to construct glucose sensing devices. MOFs are large porous crystalline compounds with versatile structural and tuneable chemical properties. In addition, they possess catalytic, peroxidase-like, and electrochemical redox activity. This review comprehensively summarizes the general characteristics of MOFs, their subtypes, and MOF composites, as well as MOF-derived materials employed to construct electrochemical, optical, transistor, and microfluidic devices for the detection of glucose. They include enzymatic, nonenzymatic, wearable, and flexible sensing devices and methods. The review also outlines the design and synthesis of MOFs and the working principles of the different transductionbased glucose sensors and highlights the current challenges and future perspectives.

“…The utilization of nanostructured materials, including transition metal oxides (NiO, Co 3 O 4 , Fe 2 O 3 , CeO 2 , CuO, etc. ), metal hydroxides, metal sulfides nanostructures, bimetallic nanomaterials, carbon nanocomposite materials, etc., have widely been engaged as successful electrode candidates for the detection of glucose due to their ease, high synergist action, and great biocompatibility [26][27][28][29]. The desirable electrodes for the design of the electrochemical glucose sensors may concomitantly have good electric conductivity and high electrocatalytic activity [30].…”

Herein, we report a non-enzymatic electrochemical glucose sensing platform based on NiS nanoclusters dispersed on NiS nanosphere (NC-NiS@NS-NiS) in human serum and urine samples. The NC-NiS@NS-NiS are directly grown on nickel foam (NF) (NC-NiS@NS-NiS|NF) substrate by a facile, and one-step electrodeposition strategy under acidic solution. The as-developed nanostructured NC-NiS@NS-NiS|NF electrode materials successfully employ as the enzyme-mimic electrocatalysts toward the improved electrocatalytic glucose oxidation and sensitive glucose sensing. The NC-NiS@NS-NiS|NF electrode presents an outstanding electrocatalytic activity and sensing capability towards the glucose owing to the attribution of great double layer capacitance, excessive electrochemical active surface area (ECASA), and high electrochemical active sites. The present sensor delivers a limit of detection (LOD) of ~0.0083 µM with a high sensitivity of 54.6 µA mM−1 cm−2 and a wide linear concentration range (20.0 µM–5.0 mM). The NC-NiS@NS-NiS|NF-based sensor demonstrates the good selectivity against the potential interferences and shows high practicability by glucose sensing in human urine and serum samples.
