Q: What is your academic and professional background? I earned a bachelor’s degree in biomedical engineering from Imperial College London and a PhD in Chemistry and Biological Sciences from Durham University. During my PhD, I developed an interest in carbon nanotechnology, which shifted my research focus. I deepened my expertise in this field as a […]

Electrochemical biosensors are innovative devices that are able to perform highly sensitive assays in short periods of time. For healthcare, environmental sciences and biotechnology, these types of biosensors have the potential to drive breakthroughs in real-time monitoring, early disease detection and precision diagnostics. However, despite their potential, the fabrication of these biosensors involve high costs, […]

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 […]

Biosensors have transformed fields such as healthcare, biotechnology and environmental science by facilitating early disease diagnosis, real-time environmental monitoring and quality control processes. Recent advances have expanded the scope of these biosensors, offering improved sensitivity, specificity and adaptability across diverse applications. As demands for stability and miniaturisation grow for these devices, cutting-edge transduction methods and […]

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 […]
