Non-covalent π–π functionalised Gii-Sens Carbon based electrode for interleukin-10 (IL-10) impedimetric detection

Highlights IL-10 acts as a gene regulator with functions encompass the suppression and termination of inflammatory immune responses. IL-10 is usually assayed using commercially available ELISA kits and its expression is evaluated through real-time PCR. All these techniques are reported as fast and straightforward; however, their sample preparation protocols are complex, not to mention the […]

Polymer of intrinsic microporosity (PIM-1) enhances hydrogen peroxide (H2O2) production at Gii-Sens electrodes

Highlights The goal of this paper was to catalyse a reaction whereby the polymer coating absorbs oxygen to enhance hydrogen peroxide production using Gii-Sens. Graphene and graphene-oxide-related materials have been shown to be active in producing hydrogen peroxide cathodically but the yield of H2O2 may vary, dependent on conditions, defects, or doping. Here, it is […]

Polymer Indicator Displacement Assay: Electrochemical Glucose Monitoring Based on Boronic Acid Receptors and Graphene Foam, Gii, Competitively Binding with Poly-Nordihydroguaiaretic Acid

Highlights Here, we propose an alternative, low-cost yet effective electrochemical glucose chemo-sensing technique based on a boronic acid functionalisation upon Gii-Sens. The new methodology is shown to give apparent saccharide – boronic acid binding constants and to work in human serum, this shows in the future that this could be developed further to develop a […]

Three-dimensional graphene foam, Gii, based triboelectric nanogenerators

Highlights Gii presents unique mechanical-to-electrical energy conversion features. Triboelectric nanogenerators based on Gii exhibit record output powers. Triboelectric nanogenerators play a key role in self-powered pressure sensing mats which are utilised to monitor anonymously room occupancy. Abstract In this work we investigate the potential of three-dimensional graphene (3DG) foam, Gii, as an active layer in […]
