From detecting biomarkers in body fluids to enabling real-time health tracking, nanomaterial-based biosensors have the potential to transform patient care for the better. However, despite their potential, there are major material challenges that stand in the way of their widespread adoption across medicine. The key materials used, such as gold and carbon-based nanomaterials like graphite […]

Researchers develop a new electrode material using sustainable carbon nanomaterial Gii, enabling smaller, more efficient energy storage for Internet of Things (IoT) devices. The material operates at 2V – nearly double the typical voltage of an electrode, reducing the size and material use. As the material is based on water, it offers a sustainable alternative […]

Highlights This work presents the electrosynthesis of a photoactive TiO2 pohase on Gii without the need for thermal annealing. Approximately 2.1x the value for traditional carbon-based printed electrodes was achieved by using Gii instead of a carbon-based electrode. Abstract We discuss the photoelectroanalytical performance of a brookite-phase titanium dioxide (TiO2) platform electrodeposited onto graphene foam […]

Highlights Electrodeposition of iron oxyhydroxide (FeOOH) onto carbon substrates based on acetate precursors was demonstrated. This Gii electrode outperformed the more established iron chloride deposition. Cycling stability of the fuel cell is reasonable at 70% retention at 5000 cycles. Abstract Electrochemical capacitors based on redox active materials can achieve greater capacitance values than traditional electric […]

Highlights Gii has high detectivity, low-cost and mass-producibility properties that could improve broadband photodetectors. Gii outperforms existing materials in terms of detection performance, while also being a low-cost, sustainable, supply-secure and commercially scalable material. Gii-powered broadband photodetectors could eliminate the cost of and space for using multiple sensing materials and ultimately offer faster fibre optic […]

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 […]
