“…Therefore, the development of a simple, fast, and accurate method for the determination of this drug in commercial pharmaceutical pills is very meaningful. So far, a lot of methods have been reported for the detection of acetaminophen including titration method [9], spectrophotography [10], high-performance liquid chromatography [11], capillary zone electrophoresis [12], fluorescence analysis [13], and electrochemical methods [14][15][16]. Among them, the electrochemical methods have attracted much attention because of their many advantages, such as, high sensitivity and selectivity, fast response, without pollution, and simple operation.…”

An electrochemical sensor of acetaminophen based on poly(diallyldimethylammonium chloride) (PDDA)-functionalized reduced graphene-loaded Al2O3-Au nanoparticles coated onto glassy carbon electrode (Al2O3-Au/PDDA/reduced graphene oxide (rGO)/glass carbon electrode (GCE)) were prepared by layer self-assembly technique. The as-prepared electrode-modified materials were characterized by scanning electron microscopy, X-ray powder diffraction, and Fourier transform infrared spectroscopy. The electrocatalytic performances of Al2O3-Au/PDDA/rGO-modified glassy carbon electrode toward the acetaminophen were investigated by cyclic voltammetry and differential pulse voltammetry. The modified electrodes of graphene oxide (GO)/GCE, PDDA/rGO/GCE, and Al2O3-Au/PDDA/rGO/GCE were constructed for comparison and learning the catalytic mechanism. The research showed Al2O3-Au/PDDA/rGO/GCE having good electrochemical performance, attributing to the synergetic effect that comes from the special nanocomposite structure and physicochemical properties of Al2O3-Au nanoparticles and graphene. A low detection limit of 6 nM (S/N = 3) and a wide linear detection range from 0.02 to 200 μM (R (2) = 0.9970) was obtained. The preparation of sensor was successfully applied for the detection of acetaminophen in commercial pharmaceutical pills. Graphical abstract Schematic diagram of synthesis of Al2O3-Au/PDDA/rGO/GCE.

“…From this perspective, the main driving force results from the synergistic effect involving the d-band center of the metal, the binding energy of which is more stabilized. Considering gold-platinum nanoalloys, the electronic exchanges between the 5d orbitals of Au (full: 5d 10 ) and Pt (unfilled: 5d 9 ) induce the modification of their valence band energy [62][63][64]. Thereafter, more hydroxyl species (the main descriptors of oxidation reactions) may be formed at the catalyst surface, leading to more active sites.…”

“…The great excitement generated by the above glucose and H 2 O 2 sensors was mostly motivated by the tunable physical, morphological and catalytic properties of nanoscale materials. To take advantage of the fascinating properties of nanomaterials, such as larger specific surface areas and the higher density of surface active sites, various methods have been developed by different groups to prepare nanostructured materials to trace other substrates within biofluids such as DNA [8,148,149], ascorbic acid [12,150,151], dopamine [11,152], acetylsalicylic acid (aspirin) [12,153], and paracetamol [9,10]. At the physiological level, ascorbic acid, commonly known as vitamin C, is a compound of great biomedical interest that plays a very important role in regulating metabolism and central nervous system functions.…”

Abstract:The future of analytical devices, namely (bio)sensors, which are currently impacting our everyday life, relies on several metrics such as low cost, high sensitivity, good selectivity, rapid response, real-time monitoring, high-throughput, easy-to-make and easy-to-handle properties. Fortunately, they can be readily fulfilled by electrochemical methods. For decades, electrochemical sensors and biofuel cells operating in physiological conditions have concerned biomolecular science where enzymes act as biocatalysts. However, immobilizing them on a conducting substrate is tedious and the resulting bioelectrodes suffer from stability. In this contribution, we provide a comprehensive, authoritative, critical, and readable review of general interest that surveys interdisciplinary research involving materials science and (bio)electrocatalysis. Specifically, it recounts recent developments focused on the introduction of nanostructured metallic and carbon-based materials as robust "abiotic catalysts" or scaffolds in bioelectrochemistry to boost and increase the current and readout signals as well as the lifetime. Compared to biocatalysts, abiotic catalysts are in a better position to efficiently cope with fluctuations of temperature and pH since they possess high intrinsic thermal stability, exceptional chemical resistance and long-term stability, already highlighted in classical electrocatalysis. We also diagnosed their intrinsic bottlenecks and highlighted opportunities of unifying the materials science and bioelectrochemistry fields to design hybrid platforms with improved performance.

“…(149,150) In particular, its strong antifouling properties would accelerate electron transfer between the recognition element and the electrode. (151) Moreover, its excellent dispersion performance also effectively prevents the irreversible agglomeration or restacking of graphene through strong π-π stacking and van der Waal's interaction. (152,153) On the basis of that, Li et al (154) used an NF-graphene-modified GCE with a bismuth film to detect Pb 2+ and Cd 2+ by differential pulse anodic stripping voltammetry (DPASV).…”

Owing to the outstanding conductivity and biocompatibility as well as numerous other fascinating properties of graphene, graphene-based nanohybrids have shown unparalleled superiorities in the field of electrochemical biosensors. We provide a general overview of recent advances and state-of-the-art works related to all types of nanomaterial, including noble metals, transition metals, organic and inorganic dyes, polymers, biomolecules, ionic liquids (ILs), and boronic acid derivatives, applied to functionalize graphene to construct electrochemical biosensors. We are highlighting here types of functionalization, assembly procedures, roles of nanomaterial, and assay strategies. Finally, some future perspectives and possible research directions are also discussed.
