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 […]

Highlights Gii-Sens can help to move benchtop devices to point of care as required in the application of such assays given it’s low cost and reliable Abnormal blood lactate concentrations resulting from conditions such as sepsis can be difficult to identify and diagnose in critically ill patients. Therefore, reliable real-time lactate detection through single-point or […]

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 […]

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 […]

Highlights Pressure sensors are widely used devices in a variety of sectors from automotive, medical, industrial and consumer devices. Currently flexible pressure sensors are primarily based on capacitive, resistive and piezoelectric methods. Advanced materials such as Gii has been proposed as a promising material due to enhanced electric properties (fast device response, low recovery time […]
