Elvira Fortunato has a career distinguished by scientific, academic, and political leadership, with recognized impact both nationally and internationally. She holds a PhD in Microelectronics and is a pioneer in the field of transparent electronics, being the inventor of the first paper transistor. She is currently the most cited researcher at NOVA University Lisbon.

She has held high-level responsibilities, notably serving as Minister of Science, Technology and Higher Education, a role in which she promoted policies to bring science, higher education, and national priorities closer together. She led structural reforms such as the revision of the funding model for higher education institutions, the creation of specific quotas for low-income students (tier A), and the launch of the FCT-Tenure program, which fostered stability in scientific careers. She also coordinated the National Semiconductor Strategy, positioning Portugal within the EU Chips Act framework.

As Vice-Rector for Research at NOVA, she led a structural transformation in the university’s research support system, established the Strategic Council for Science, created the NOVA Science journal and NOVA Science Day, and restructured the Research Support Office to focus on scientific strategy, project management, and research information systems. During this time, she also championed gender equality, coordinating the SPEAR project and founding the Office for Equality and Inclusion.

She served as Chief Scientific Advisor to the European Commission, providing direct scientific advice to EU Commissioners and coordinating strategic studies on technologies for carbon capture and sustainable mobility within the EU's Scientific Advice Mechanism.

Scientifically, she directed the Associated Laboratory i3N, a European reference in advanced materials, sustainable electronics, and nanotechnology, which has secured twelve ERC grants, hundreds of international projects, and dozens of patents. Under her leadership, i3N became the most prominent research institute in Portugal in Materials Science and Nanotechnology, pioneering the first national PhD program in Nanoscience and Nanotechnologies.

Her achievements have earned her over 50 national and international honors, including the Pessoa Prize, the European Commission Horizon Impact Award, the Human Rights Medal of the Portuguese Parliament, and recognition as one of the 27 most inspiring women in Europe by the French Presidency of the EU.

Beyond her scientific contributions, she is a passionate advocate for science education as a driver of social and economic development, promoting STEM fields, gender equality, and the training of new generations of scientists. She regularly participates in international conferences, forums, and science outreach initiatives, affirming science as a tool for inclusion, accessibility, and sustainability. Her vision integrates research, innovation, science policy, and civic commitment—reflected in a career of real, transformative, and lasting impact in service of society.

Abstract:

Electrochemically active bacteria (EAB) have the capability to transfer electrons to cell exterior, a feature that is currently explored for important applications in bioremediation and biotechnology fields. However, the number of isolated and characterized EAB species is still very limited regarding their abundance in nature. Colorimetric detection has emerged recently as an attractive mean for fast identification and characterization of analytes based on the use of electrochromic materials. In this work, WO3 nanoparticles were synthesized by microwave assisted hydrothermal synthesis and used to impregnate non-treated regular office paper substrates. This allowed the production of a paper-based colorimetric sensor able to detect EAB in a simple, rapid, reliable, inexpensive and eco-friendly method. The developed platform was then tested with Geobacter sulfurreducens, as a proof of concept. G. sulfurreducens cells were detected at latent phase with an RGB ratio of 1.10 ± 0.04, and a response time of two hours.
