iGii's Research Round Up December 2025

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 […]

Welcome to the second of the Research Roundup series. In this series, we provide brief updates on the latest academic research across the world making use of our 3D carbon nanomaterial, Gii. Here, we explore the potential of Gii for sensing with aptamers and exploring varying techniques for glucose testing. 1. Gii-based aptasensors to enhance […]

iGii commissioned Anthesis to conduct a comparative screening life cycle analysis (LCA) on our Gii-Sens Biosensors range to help us understand the carbon footprint of our manufacturing process in a 4-month project. Gii Sens Biosensors range, powered by Gii – iGii’s pure 3D carbon nanomaterial with a large active surface area and innate antifouling properties […]

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 […]
