Can we cut the energy consumption of current AI technologies?

As artificial intelligence, commonly referred to as AI, becomes increasingly integrated into various aspects of our daily lives, the energy demands of AI systems continue to rise. Despite AI being inspired by the human brain, it is significantly less energy efficient because most tasks are implemented on computer hardware that is not specifically tailored for this purpose. The human brain remains an exemplar of energy-efficient computation, a standard that modern technology strives to replicate. INL researchers are studying advanced materials and devices aimed at revolutionising AI systems. Carlos Rosário, ERA fellow at INL (Marie Skłodowska-Curie actions (MSCA)), focuses his research on reducing the substantial energy consumption required by current AI technologies. Carlos’ work is grounded in the field of neuromorphic computing, which seeks to mimic the brain’s intricate network of neurons and synapses using artificial equivalents. The goal is to create an electronic brain capable of performing complex computations with minimal energy use. One of the key areas of Carlos Rosário’s research is the exploration of 3D topological insulators for novel electronic devices. These cutting-edge materials exhibit unique properties: while they are insulators and do not conduct electricity through their bulk, their surfaces behave like metals, allowing for efficient electrical […]

Breakthrough technology for cancer diagnostics

INL researchers are part of the consortium behind BIOCELLPHE, a pioneering project focused on advancing cancer diagnostics and personalised medicine. This innovative European-funded project is at the forefront of scientific and technological innovation, introducing a groundbreaking technology for identifying proteins as diagnostic biomarkers at the single-cell level. This new approach offers multiplexing capabilities, portability and enhanced sensitivity. Alexandra Teixeira, research fellow at the Medical Devices group, highlights that “BIOCELLPHE is pioneering the use of engineered bacteria to recognise and bind with high specificity to protein targets on the surface of circulating tumour cells, or CTCs, which are key players in cancer metastasis.” This specific binding of engineered bacteria to CTCs subsequently triggers the production of molecules (Raman reporters), which can be detectable with high sensitivity using surface-enhanced Raman scattering (SERS). More specifically, SERS uses plasmonic nanoparticles to enhance Raman signals, allowing ultrasensitive analysis and detection at the single molecule level. The pathological role of CTCs in cancer metastasis is not completely understood due to the lack of effective analytical tools and remains an area that needs further exploration. BIOCELLPHE addresses this gap by developing new tools for the phenotypic identification of CTCs at the single-cell level, with high-throughput and multiplexing […]

A miniaturised model of human digestion to advance therapies and nutritional products

INL researchers have made a significant breakthrough in the development of reliable in-vitro digestion models. This ‘digestion-chip’ promises to revolutionise the way new oral formulations are tested, offering a more accurate, efficient, and cost-effective alternative to current models. Traditional in-vitro digestion models often fail to replicate the complex dynamics of the human gastrointestinal tract. They either lack critical digestive processes or require large volumes of samples and reagents, which can be challenging when dealing with nanomaterials. The INL’s innovative ‘digestion-chip’ addresses these limitations with its miniaturised design and advanced features. The coordinator of the study Catarina Gonçalves explains, “the Food Processing and Nutrition research group proposes a miniaturised digestion system based on incubation chambers integrated into a polymethylmethacrylate device. This solution incorporates key dynamic features of human digestion while maintaining low complexity and using small volumes of samples and reagents”. The digestion-chip features gradual acidification (the stepwise addition of enzymes and simulated fluids during the gastric phase) and controlled gastric emptying. These capabilities are essential for replicating the intricate environment of the human stomach and intestines. The research team’s experimental results indicate that “the ‘digestion-chip’ successfully replicates the established static digestion INFOGEST protocol”. Moreover, “the semi-dynamic digestion kinetics observed with […]

Innovative graphene oxide sensor detects low concentrations of nitrate in water

A new study published in the Chemosensors journal introduces a novel approach to nitrate ion detection using all-solid-state ion-selective electrodes enabled by graphene oxide as an ion-to-electron transducer. Nitrate ions play a critical role in the nitrogen cycle in natural ecosystems, such as in soils and aquatic environments. However, their levels have dramatically increased due to modern agricultural practices. The excessive use of inorganic fertilizers has led to high concentrations of nitrate in surface and groundwater, posing significant environmental and health risks. Eutrophication, which is a phenomenon caused by nutrient overload in water bodies, results in uncontrolled algae growth, oxygen depletion, and poor water quality. This negatively impacts biodiversity, fisheries, and recreational activities. Moreover, if nitrate concentration exceeds a certain level (the value established by the European Union is 50mg/L), water may become unsuitable for consumption, potentially leading to severe health issues such as colorectal cancer and thyroid disease. INL researchers have developed an innovative sensor that can robustly detect low concentrations of nitrate in water. Despite being effective, traditional methods for nitrate detection are time-consuming and expensive. Electrochemical sensors offer a promising alternative due to their simplicity, cost-effectiveness, and rapid response time – particularly potentiometric ion-selective electrodes. However, early […]
