A new tool being developed at INL can explore electrical effects on cells

While we usually consider electronics as a fruit of human engineering, electrical signalling is also fundamental in biology, playing an essential role in cellular functions from neuronal communication and muscle contraction to cell migration, proliferation and differentiation. Electrical stimulation activating these biological functions is therefore also a powerful tool for both fundamental research and for therapeutic applications. Alar Ainla, research scientist at INL, in collaboration with the Life and Health Sciences Research Institute (ICVS) at the University of Minho, has developed a novel multi-channel in vitro electrical stimulator to help study these effects in a versatile and accessible way. Their work was published in BMC Biomedical Engineering. Cells can sense and respond to the electric fields. Exposure to an electric field changes the electrical potential across the cell membrane, influencing voltage-gated ion channels and calcium signalling, which can trigger nerve impulses, muscle contraction, and even long-term processes like synaptic plasticity, cell proliferation, and differentiation. In stem and neuronal cells, electrical stimulation can promote axon growth, enhance the expression of neuronal markers, and trigger the release of molecules that guide the differentiation of neighbouring cells. In other words, cells behave like tiny sensors and communicators, adjusting their internal processes in response […]

Shedding light on ultrafast heat transport in graphene

Managing heat efficiently is one of the great challenges in the development of next-generation electronic and optoelectronic devices. At the nanoscale, energy moves in ways that defy classical descriptions of heat transfer. Houssem Rezgui, researcher from the Sotomayor research group at INL, has now provided new insights into how energy flows in graphene when excited with ultrafast laser pulses. Their work, published as a Letter in Journal of Physics D: Applied Physics, explores how electrons and vibrations in the lattice (known as phonons) interact in timeframes shorter than a trillionth of a second. Graphene, with its remarkable electronic and thermal properties, is an ideal platform for probing these processes. When struck by a femtosecond laser pulse, graphene enters a highly non-equilibrium state: electrons absorb the incoming energy almost instantly, and only afterward begin to share it with the lattice. Traditionally, this sequence has been described by the two-temperature model, which assumes that electrons and phonons equilibrate in a straightforward way. However, the INL researcher shows that reality is more complex. Using an extended temperature model, Rezgui revealed that different phonon branches respond at distinct timescales, with longitudinal acoustic phonons playing a key role in energy absorption and redistribution. Strikingly, their […]

Magnetic nanowires take hydrogen production to the next level

As the world looks for cleaner ways to produce energy, green hydrogen (fuel made from water and renewable electricity) is gaining attention as a promising solution. To make green hydrogen affordable and efficient, better catalysts are needed to speed up the chemical reactions involved. Researchers at INL – International Iberian Nanotechnology Laboratory have developed a new type of magnetic catalyst that could change the game. Their findings, recently published in ACS Nano, reveal how these magnetic nanowires efficiently catalyse the oxygen evolution reaction, a key reaction in hydrogen production from water. The research team led by Yury Kolen’ko created cobalt ferrite (CoFe2O4) nanowires using a technique called electrospinning, which forms ultra-thin fibres by using an electric field to draw solid threads from a liquid solution; imagine sugar being spun into cotton candy, but at the nanoscale. By precisely controlling the calcination temperature, the team transformed the fibres into nanowires with excellent magnetic properties, critical for their catalytic performance. Why does magnetism matter? The oxygen molecules, which are formed during the water-splitting process, have a special triplet spin state. When the catalyst is magnetic, it can influence the spin alignment of the reaction intermediates, guiding the reaction to proceed faster and […]

Eco-friendly sensor developed at INL enables rapid detection of pharmaceutical contaminants in water

Pharmaceutical waste in water sources is becoming a growing environmental concern. Among the most common pollutants are paracetamol and 4-aminophenol, a related compound that can appear as a contaminant or breakdown product. These substances persist in urban wastewater and surface waters, potentially harming aquatic ecosystems and human health. Detecting them accurately and efficiently is crucial for environmental protection and risk management. Researchers at INL from Espiña’s research group have designed an innovative electrochemical sensor that can simultaneously detect both pharmaceuticals at very low concentrations. The sensor uses carbon screen-printed electrodes modified with specially functionalised carbon nanofibers, which enhance sensitivity and selectivity. This study published in the journal Sensing and Bio-Sensing Research, describes a solution for portable, cost-effective, and environmentally friendly tool for water quality monitoring. Traditional methods for identifying pharmaceutical contaminants often rely on complex laboratory techniques such as chromatography and spectrometry. While highly precise, these require expensive equipment, trained personnel, and time-consuming sample preparation, limiting their use for routine or on-site testing. In contrast, electrochemical sensors like the one developed by the INL team led by Raquel Queirós, provide rapid, real-time results with minimal costs. The research team compared different transducer materials, finding that carbon-based ones performed better than […]

Cristiana Alves: Revealing the Invisible Through Materials Science

Meet Cristiana Alves, Facility Lead at the Electron Microscopy and X-Rays (EMX) Facility at INL. With a lifelong curiosity for how things work and a deep passion for uncovering the unseen, Cristiana’s journey into materials engineering and nanotechnology has been driven by both precision and wonder. From exploring bioactive coatings for dental implants during her PhD to working in one of the most advanced electron microscopy facilities in the Iberian Peninsula, she combines technical excellence with a commitment to discovery. At the heart of her work is a drive to understand materials at their most fundamental level, and to help others do the same.

INL Workshop on Medical Devices Helps Shape EU Policy Milestone in Advanced Materials

Just months after INL hosted a high-level workshop on Advanced Innovative Materials for Medical Devices, the momentum generated in Braga has culminated in a major policy advancement: At its second meeting, the High Level Technology Council for Advanced Materials, held in Brussels last week, expanded its industry priorities to include advanced materials for medical devices. This marks a significant recognition of the groundwork of the subgroup tasked with examinign this option discussed at INL in April, where European leaders, policymakers, and innovators gathered to explore the transformative potential of advanced materials in health materials and associated technologies. “The inclusion of materials for health in the form of medical devices is a strategic priority for Europe,” said Dr Clivia Sotomayor Torres, Director-General of INL, who chaired the subgroup with support form Dr Lorena Diéguez, research group leader at INL. She added: “it’s a testament to the power of collaborative dialogue and scientific foresight.” From INL to Brussels: Driving the Agenda Forward Organised under the High Level Technology Council for Advanced Materials, an initiative of the European Commission launched in late 2024, the April 2025 workshop at INL served as a strategic forum under the Council’s Subgroup on Future Priorities. It brought together key European figures including Irene […]
