Scientists at the University of the West of Scotland and University of Glasgow find carbon nanomaterial Gii has high detectivity, low-cost and mass-producibility properties that could improve broadband photodetectors. Broadband photodetectors are used in fibre optic networks and medical imaging devices. Latest study finds Gii outperforms existing materials in terms of detection performance, while also […]

Highlights Gii-Sens has shown to be ideal electrodes for glucose biosensors. Glucose sensitivity of 22.7 μA/mM/cm^2 shows promise for metal-free sensors. The observable biocatalytic response from the electrodes, prepared through simple drop-casting methods onto commercially available 3D graphene foams, represents a promising first step to the development of metal-free biocatalytic devices based on this setup […]

Highlights The Adsorption of a pyrene-appended receptor molecule onto Gii causes significant capacitance changes (when positively charged pyridinium group is attached close to the Gii surface). Gii provides a great platform for sensing mechanism based on capacitance changes. The use of quantum capacitance in sensing can open new opportunities in wireless sensing but more in-depth […]

Highlights This label-free electrochemical immunosensor based on Gii-Sens uses the bioreceptor (mAb-cort) and analyte (cortisol) in their natural forms without any modification to study their biomolecular interaction with high affinity by decreasing non-specific adsorption. Some salient features of the proposed graphene-based (Gii) cortisol immunosensor are its simple fabrication, low cost, higher selectivity, reproducibility, and superior […]

Pioneering saliva-based point-of-care electrochemical biosensor developed for real-time cortisol tracking – avoiding the need for invasive blood tests. Underpinned by a Gii-Sens electrode, comparative studies reveal the biosensor has 100 times greater sensitivity compared to traditional saliva tests, ensuring reliable cortisol level measurements. Applications include identifying early onset of stress related metabolic and neurological disorders, […]

iGii, announces £8.8m in new funding to accelerate growth. The Stirling-based company, formerly known as Integrated Graphene, will use the funds to accelerate customer projects, increase its manufacturing capacity, and deepen its research and development to explore further applications of its patented Gii™ material. iGii plans to expand its facilities and continue creating highly skilled […]

Scientists at the University of Bath, UK, introduce breakthrough carbon-based sensor for detecting lactic acid levels in saliva – avoiding the need for an electrical power source. Underpinned by a Gii-Sens electrode platform, the Gii chemosensor could have potential for highly sensitive lactic acid testing in remote locations without needing a lab. Applications could include […]

Dr. Jo Holmes has been appointed to spearhead sales of Gii-Sens, its world leading electrochemical electrode. With a distinguished background in electrochemistry spanning both business and academia, Dr. Holmes brings a wealth of expertise to the team. In this newly created role, she will collaborate with new and existing customers to integrate Gii-Sens into their […]

Highlights Graphene foams (Gii) with electrodeposited birnessite MnO2 via current pulse achieved a maximum capacitance of 530 mF/cm2 at 10 mA/cm2 compared to 385 mF/cm2 for galvanostatic deposition and 240 mF/cm2 for cyclic voltammetry deposition at the same current density. Current pulse MnO2 electrode demonstrated better rate capability (61% capacitance retention switching from 0.5 to 20 mA/cm2) and cycling retention (93% after 5000 […]
