Abstract
The effective regeneration of bioactive NAD+ plays an important role in numerous dehydrogenase-dependent applications including biocatalysis and biosensing. However, this process usually suffers from high thermodynamic barrier, instability and high cost associated with natural enzymes. The emergence of nanomaterials with enzyme mimic characteristics has offered a potential alternative to many enzyme-catalyzed processes. Platinum nanoparticles (PtNPs), for example, have been extensively studied for their peroxidase- and oxidase-like activities. However, their behavior as a NADH oxidase mimic has barely been characterized in detail. Herein, we report a facile approach for preparing PtNP-deposited multi-walled carbon nanotubes (PtNPs@MWCNTs) as the nanozyme for NADH oxidation. Its enzymatic activity was investigated in depth, revealing that it is a NADH oxidase instead of a peroxidase and the catalytic process generates O2˙-, rather than OH˙ or 1O2, from dissolved O2. The recovery yield of bioactive NAD+ regeneration by the nanozyme could reach ∼100% with a total turnover number of ∼6000. Besides, it exhibited terrific electrochemical performance for NADH oxidation and sensing by greatly boosting the response and lowering the oxidation overpotential. It could also work on biomimetic cofactors with even higher activity. Finally, xylose dehydrogenase was immobilized with the nanozyme to constitute a hybrid bioelectrode for xylose sensing. The biosensor had a xylose detecting range of 5-400 μM with the limit of detection as low as 1 μM and can retain its performance after being reused several times. Our results suggest that the PtNPs@MWCNTs characterized as a NADH oxidase nanozyme hold great promise in the applications of biocatalysis and biosensing, which intensively deal with dehydrogenases and natural or biomimetic cofactors.

Abstract
In this work, a novel electrochemical sensing platform was designed and fabricated by the modification of boronic acid functionalized carbon nanodots (B-CNDs) and poly(thionine) (pTHI) on an electrode surface. B-CNDs can not only accelerate electron transfer but also covalently interact with cis-diol groups of dihydronicotinamide adenine dinucleotide (NADH) through functionalized boronic acid groups. Meanwhile, pTHI served as an inner reference element to provide a built-in correction, which enabled the sensor to detect NADH with high accuracy and reliability based on a ratiometric signal (∆INADH/∆ITHI). The electrochemical experimental results demonstrated that the ratiometric strategy-based sensor possessed good selectivity and high sensitivity. A linear range of 5.0 × 10-7 - 2.0 × 10-4 mol/L for NADH detection was obtained with a limit of detection of 1.5 × 10-7 mol/L. The sensor has been applied to analyze NADH in human serum samples with satisfactory results. The simple and effective ratiometric strategy reported here can be further used to prepare electrochemical sensors for selective, sensitive, and reliable detection of other cis-diol compounds.

Abstract
Application of enzymatic biofuel cells (EBFCs) in wearable or implantable biomedical devices requires flexible and biocompatible electrode materials. To this end, freestanding and low-cost graphene paper is emerging among the most promising support materials. In this work, we have exploited the potential of using graphene paper with a two-dimensional active surface (2D-GP) as a carrier for enzyme immobilization to fabricate EBFCs, representing the first case of flexible graphene papers directly used in EBFCs. The 2D-GP electrodes were prepared via the assembly of graphene oxide (GO) nanosheets into a paper-like architecture, followed by reduction to form layered and cross-linked networks with good mechanical strength, high conductivity and little dependence on the degree of mechanical bending. 2D-GP electrodes served as both a current collector and an enzyme loading substrate that can be used directly as a bioanode and biocathode. Pyrroloquinoline quinone dependent glucose dehydrogenase (PQQ-GDH) and bilirubin oxidase (BOx) adsorbed on the 2D-GP electrodes both retain their biocatalytic activities. Electron transfer (ET) at the bioanode required Meldola blue (MB) as an ET mediator to shuttle electrons between PQQ-GDH and the electrode, but direct electron transfer (DET) at the biocathode was achieved. The resulting glucose/oxygen EBFC displayed a notable mechanical flexibility, with a wide open circuit voltage range up to 0.665 V and a maximum power density of approximately 4 μW cm-2 both fully competitive with reported values for related EBFCs, and with mechanical flexibility and facile enzyme immobilization as novel merits.

Abstract
A new cellulose nanocrystal-reduced graphene oxide (CNC-rGO) nanocomposite was successfully used for mediatorless electrochemical sensing of methyl paraben (MP). Fourier-transform infrared spectroscopy (FTIR) and field-emission scanning electron microscopy (FESEM) studies confirmed the formation of the CNC-rGO nanocomposite. Cyclic voltammetry (CV) studies of the nanocomposite showed quasi-reversible redox behavior. Differential pulse voltammetry (DPV) was employed for the sensor optimization. Under optimized conditions, the sensor demonstrated a linear calibration curve in the range of 2 × 10-4-9 × 10-4 M with a limit of detection (LOD) of 1 × 10-4 M. The MP sensor showed good reproducibility with a relative standard deviation (RSD) of about 8.20%. The sensor also exhibited good stability and repeatability toward MP determinations. Analysis of MP in cream samples showed recovery percentages between 83% and 106%. Advantages of this sensor are the possibility for the determination of higher concentrations of MP when compared with most other reported sensors for MP. The CNC-rGO nanocomposite-based sensor also depicted good reproducibility and reusability compared to the rGO-based sensor. Furthermore, the CNC-rGO nanocomposite sensor showed good selectivity toward MP with little interference from easily oxidizable species such as ascorbic acid.

Abstract
Stable solid-state red fluorescence from organosilane-functionalized carbon dots (CDs) with sizes around 3 nm is reported for the first time. Meanwhile, a novel method is also first reported for the efficient construction of dual-fluorescence morphologies. The quantum yield of these solid-state CDs and their aqueous solution is 9.60 and 50.7%, respectively. The fluorescence lifetime is 4.82 ns for solid-state CDs, and 15.57 ns for their aqueous solution. These CDs are detailedly studied how they can exhibit obvious photoluminescence overcoming the self-quenching in solid state. Luminescent materials are constructed with dual fluorescence based on as-prepared single emissive CDs (red emission) and nonfluorescence media (starch, Al2 O3 , and RnOCH3 COONa), with the characteristic peaks located at nearly 440 and 600 nm. Tunable photoluminescence can be successfully achieved by tuning the mass ratio of CDs to solid matrix (such as starch). These constructed dual-fluorescence CDs/starch composites can also be applied in white light-emitting diodes with UV chips (395 nm), and oxygen sensing.

Abstract
Silver nanoparticles (NPs) decorated nitrogen doped graphene (NG) nanocomposites were prepared through a one-step thermal-treatment route using arginine as the nitrogen source. By integrating the excellent electrical properties and large surface area of Ag NPs and NG, the obtained Ag/NG nanocomposites show more effective electron transfer and high loading capacity than Ag-graphene and pure NG. In the presence of a target, the stronger interaction between the aptamer and the target promotes the formation of a target-aptamer complex on the electrode surface which blocks the electron transfer. Based on this sensing mechanism, a novel and highly sensitive biosensing platform by the use of Ag/NG as enhancing materials is demonstrated for detection of the model target, acetamiprid. The presented aptasensor exhibited a wide linear response for acetamiprid in the range of 1 × 10(-13) M to 5 × 10(-9) M with a low detection limit of 3.3 × 10(-14) M (S/N = 3). Moreover, this electrochemical aptasensor avoided complicated labeling procedures and showed magnificent sensitivity, high selectivity and low cost, which made it not only convenient but also time-saving and applicable. Furthermore, the proposed design may offer a promising way to develop a new electrochemical aptasensor for sensitive and specific detection of a wide spectrum of analytes in food, medical and environmental fields.

Abstract
Hydroxypropyl carboxymethyl cellulose samples having varying degrees of substitution and varying degrees of polymerization were used to reduce silver nitrate to silver nanoparticles. UV spectral analysis of silver nanoparticles colloidal solution reveal that increasing the pH of the reduction solution leads to improvement in the intensity of the absorption band for silver nanoparticles, to be maximum at pH 11. The absorption peak intensity also enhanced upon prolonging the reaction duration up to 60 min. The conversion of silver ions to metallic silver nanoparticles was found to be temperature-dependent and maximum transformation occurs at 60 °C. The reduction efficiency of hydroxypropyl carboxymethyl cellulose was found to be affected by its degree of polymerization. Colloidal solutions of silver nanoparticles having concentration up to 1000 ppm can be prepared upon fixing the ratio between silver nitrate and hydroxypropyl carboxymethyl cellulose at 0.017-0.3g per each 100ml of the reduction solution.
