Abstract
The simultaneous detection of multiple biological small molecules is critical for human health evaluation and disease prevention. In this study, a nano-ZnS decorated hierarchically porous carbon (ZSHPC) electrocatalyst with multiple enzyme-like activities as a nanozyme sensing platform for simultaneous derivative voltametric detection of four important biological small molecules, dopamine (DA), uric acid (UA), guanine (G), and adenine (A), is successfully synthesized via an in situ hydrothermal reaction using leaves of Cinnamomum camphora (L.) after the extraction of essential oil as a carbon source, ZnCl2 as both zinc source and an activator, sulfuric acid as a sulfur source, and silica gel as a hard template. Activator together with the introduction of silica gel is beneficial for tuning pore structure. The in situ synthesized ZnS nanoparticles and sulfur doping improve the conductivity and cycling stability of the material. The ZSHPC electrode with multiple enzyme-like activities and oxidase-like characteristics was employed for the simultaneous detection of multiple target molecules in linear ranges of 0.3-500 μM with detection limits of 0.12 μM for DA, 0.26 μM for UA, 0.07 μM for G, and 0.075 μM for A. A derivative technique was selected for enhancing the peak resolution of the partial overlapped voltammograms and eliminating human error. Both the coefficient of determination and residual prediction deviation were used to evaluate this technique.

Abstract
A novel electrochemically activated nanocomposite, CoS2 Nanoparticles and MoS2 Nanosheets decorated poly(diallyldimethylammonium chloride)-functionalized graphene (CoS2-MoS2-PDDA-GR), was successfully synthesized through a simple and low-cost method. X-ray diffraction (XRD), Transmission electron microscopy (TEM), Electrochemical impedance spectroscopy (EIS) and Cyclic voltammetry (CV) techniques were used to characterize the nanocomposites. Based on the CoS2-MoS2-PDDA-GR nanocomposite modified glassy carbon electrode, the electrochemical properties of eriocitrin were investigated in detail and a sensitive determinative method was established synchronously. Compared with others, this sensor exhibited larger effective surface area, more reactive site and excellent voltammetric response for eriocitrin. Under optimum conditions by DPV, the oxidation peak currents responded to eriocitrin linearly over a concentration range from 2.0 × 10-9 to 1.0 × 10-6 mol L-1 with a detection limit of 6.7 × 10-10 mol L-1 (S/N = 3). In addition, this fabricated sensor was successfully applied to detect eriocitrin in real samples with satisfactory results.

Abstract
This study demonstrated a facile method to form a porous polymeric membrane, immobilizing a biocatalyst. A polyelectrolyte-based amphiphilic diblock copolymer, i.e., polystyrene-block-poly(acrylic acid) (PS-b-PAA), self-assembled with hemoglobin (Hb) dually driven by charge and amphiphilicity during solution-casting and evaporation. XPS and contact angle measurements suggested that the PS block enriched on the membrane surface. The PAA block pointed toward the internal membrane as well as ordered the Hb arrangement at the interface of the polymer and electrode. The obtained PS-b-PAA/Hb electrode showed a remarkably enhanced direct electron transfer (ET), which was revealed to be a surface-controlled process accompanied by single-proton transfer. The membrane was tested to catalyze the reduction of hydrogen peroxide, and exhibited an excellent reproducibility and stability. This method with a charge and amphiphilicity dually driven (CADD) self-assembly opened up a new way to construct a third-generation electrochemical biosensor.
