“…[1,2]. As a type of glycoprotein with iron porphyrin as the electroactive center [3], horseradish peroxidase (HRP) has been widely used in electrochemical biosensors. However, the electroactive centers of HRP are deeply embedded inside the biostructure of the protein, making it difficult to realize the direct electron transfer with the substrate electrode.…”

To design a new electrochemical horseradish peroxidase (HRP) biosensor with excellent analytical performance, black phosphorene (BP) nanosheets and single-walled carbon nanotubes (SWCNTs) nanocomposites were used as the modifier, with a carbon ionic liquid electrode (CILE) as the substrate electrode. The SWCNTs-BP nanocomposite was synthesized by a simple in situ mixing procedure and modified on the CILE surface by the direct casting method. Then HRP was immobilized on the modified electrode with Nafion film. The electrocatalysis of this electrochemical HRP biosensor to various targets was further explored. Experimental results indicated that the direct electrochemistry of HRP was realized with a pair of symmetric and quasi-reversible redox peaks appeared, which was due to the presence of SWCNTs-BP on the surface of CILE, exhibiting synergistic effects with high electrical conductivity and good biocompatibility. Excellent electrocatalytic activity to trichloroacetic acid (TCA), sodium nitrite (NaNO2), and hydrogen peroxide (H2O2) were realized, with a wide linear range and a low detection limit. Different real samples, such as a medical facial peel solution, the soak water of pickled vegetables, and a 3% H2O2 disinfectant, were further analyzed, with satisfactory results, further proving the potential practical applications for the electrochemical biosensor.

“…This amplification has increased the use of GO in various industries such as aerospace, automotive, electronics and military fields [30,31]. GO nano-platelets and their derivatives are nanofillers that mostly utilized in various polymer matrix because of their exceptional properties (such as high thermal stability, high Young's modulus, high electrical conductivity) and extraordinary physical structure [32]. GO nano-platelets can be found in the form of a single-atom-thick-sheet which make them useful for developing nanocomposites [33].…”

The main problem of uncompatibilize rubbers nano-composites in polymeric matrix are accumulation and agglomeration of graphene oxide. In this study, EPDM-g-MA was used as a compatibilizer for better dispersion of graphene oxide (GO) in the phenyl-vinyl-methyl-polysiloxane/chloroprene rubber (PVMQ/CR) matrix. To achieve this purpose mechanical characterizations, rheology, morphology and curing characterizations of nano-composite was investigated. SEM and TEM were used to assess surface characteristics, morphology and dispersion of EPDM-g-MA in PVMQ/CR nano-composite, which showed the size of EPDM-g-MA in the blends became smaller, denser and more uniform. Also, the results showed that, by increasing the GO nano-platelets in PVMQ/CR matrix during the reaction with EPDM-g-MA, curing properties was improved such a way that optimum curing time and scorch time were decreased and also MH–ML and cure rate index (CRI) were increased and also toughness strength enhanced. In addition, the mechanical properties indicated that tensile strength, fatigue strength, hardness, elongation-at-break and modulus increased by the incorporation with GO nano-platelets.
