Highlights Gii-based electrochemical biosensor detections of key Alzheimer’s Disease biomarkers at the attomolar. The promising results indicate that Gii-Sens biosensors could drive a new generation of cost-effective, portable and reliable point-of-care devices for early detection of Alzheimer’s Disease, improving patient prognosis.  Abstract Alzheimer’s Disease (AD) is one of the most commonly seen neurodegenerative disorders, where […]

Highlights Gii based interdigitated electrodes are robust and practical for voltammetry and generator-collector experiments Formation of Prussian blue triggered by positive applied potentials at the Gii-based electrodes to be deposited selectively and used as a collector electrode for the detection of hydrogen peroxide. Abstract Gii-based interdigitated microband array electrodes with typically 400 μm width and […]

Welcome to the Research Roundup series. In this series, we provide brief updates on the latest academic research across the world making use of our sustainable carbon nanomaterial, Gii. 1. Gii in an electrochemical impedance-based capacitance sensing What is it? This study evaluates the influence of pH changes to the capacitance of Gii-Sens cards with […]

Highlights Development of a promising antibody-based Gii-Sens biosensor for the sensitive and selective detection of Tau-441 protein, an Alzheimer’s Disease biomarker.  Detection levels down to the femtomolar (0.14 fM) and linear range of 1 fM to 10 nM.  The simple, ultrasensitive electrochemical immunosensor presented in the publications show great potential in paving the way for […]

Highlights TENG powered by Gii added potential for energy harvesting from footsteps (around 60 μW per footstep). This opens the potential for a sustainable, low-maintenance management system. Both mats exhibit mechanical robustness throughout the fatigue tests, with values recorded remaining within ±2 % of initial values to the end. Abstract Real-time occupancy data enable smart-building […]

Highlights The work demonstrated a promising alternative for non-enzymatic and real-time monitoring with an electrochemical glucose detection method with Gii-Sens functionalised with gold nanoparticles that offers improved sensitivity and lower limits of detection for smart glucose monitoring. Sensitive and reliable detection range from 5mM to 25mM.  With further optimisation and development of the system, the […]

Highlights Observation of strongly enhanced capacitance (quantum capacitance) when adsorbing 1-pyrene-methylamine to graphene foam. Proton activity specific sensor response in both aqueous buffer media and in human serum. Electrochemical impedance-based capacitance sensing with future opportunity to employ wireless capacitance readout. Abstract The interfacial capacitance of graphene foam electrodes (Gii-Sens) in contact to aqueous media (determined […]

Highlights An aptamer-based sensor was developed for the detection of ciprofloxacin, the active pharmaceutical ingredient of the antibiotic, with a cost-efficient, faster and better electrochemical test based on Gii. Low limits of detection were recorded down to 3nM, with a dynamic range of 10nM to 100nM. This development has shown great potential for use in […]

Highlights Small amounts of water can considerably alter reactivity at graphene foam electrode | ionic liquid interfaces Redox probes such as FeCp2+/0 or Fe3+/2+ in BMIM+BF4– are affected by humidity increasing diffusion rates. However, on graphene foam electrode surfaces with approx. 40 μm depth, both types of redox probes show voltammetric features associated with diffusional trapping within […]
