Congratulations on receiving the 2024 EuChemS Lecture Award! What does this recognition mean to you personally and professionally?
MC: Receiving the 2024 EuChemS Lecture Award is a great honor, both personally and professionally. It represents recognition of many years of work, effort, and passion for research, as well as the support of all the people and teams with whom I have had the privilege of collaborating. This award is a great motivation to continue promoting collaborative science capable of generating knowledge with a real impact on society. Also, it is an incentive to continue training new generations of researchers and strengthening the international reach of our research.
Could you share a bit about your scientific journey? What first drew you to chemistry, and how did your path lead you to this point?
MC: When I was a kid, I was deeply curious about science and loved chemistry and biology. I quickly realized I wanted to study chemistry. As soon as I learned about the possibilities of an academic career, I wanted to put all my energy into it. My goal was to start and grow my own research group. My interest in chemical sensors and their benefits for society began early on, during my second year as an undergraduate. It has been the subject of my research interest ever since. I also wanted to gain experience in different universities and work environments, which is why I developed my career in various countries: Spain, Switzerland and Sweden.
Your research focuses on ion sensing, ion-selective electrode development, and innovative (bio)chemical sensor technologies. Could you explain these areas in more detail for our readers?
MC: My research focuses on the development of electrochemical sensors capable of detecting ions and molecules with high selectivity and sensitivity. In particular, I work with ion-selective electrodes, devices that transform the activity of an ion into a measurable electrical signal, enabling rapid and accurate analysis in complex media. Furthermore, I explore novel (bio)chemical sensor design strategies, employing advanced materials, 3D printing, and miniaturized technologies to create portable and sustainable devices that facilitate real-time environmental, biomedical, and food monitoring. Fundamental studies are guided by their future applied aspects.
What are some of the practical applications of your work, both in everyday life and in advancing scientific research?
MC: The development of electrochemical sensors opens up multiple practical applications, both in everyday life and in scientific research. They enable rapid and accurate monitoring of environmental pollutants, contributing to more sustainable resource management and environmental protection. In health and well-being, they facilitate the early detection of biomarkers and the monitoring of clinical parameters, improving quality of life. Furthermore, these sensors advance scientific research by offering versatile, miniaturized tools for real-time chemical analysis. For example, we are working on nanosensors that can measure inside a single cell. Just analyzing the pH evolution of cancerous cells, we could help the development and efficiency evaluation of new treatments.
Environmental and sustainability considerations are increasingly important in science. How do these aspects feature in your research?
MC: Sustainability is a central focus of our research. We work on developing electrochemical sensors designed with more sustainable materials and low-impact manufacturing processes, such as 3D printing and the use of green solvents. Also, we put forward sensor-actuator devices to account for in-situ sample pre-treatment without the need of adding chemical reagents. The electrochemical sensors we conceive enable rapid and accurate monitoring of pollutants, supporting more efficient and sustainable agriculture, as well as applications in health and wellness that improve quality of life.
Every researcher faces obstacles along the way. Could you talk about some challenges you have encountered and the achievements you are most proud of?
MC: Research involves overcoming constant challenges: the uncertainty of results, competition for funding, and the need to balance creativity with rigor. I am glad to have built a diverse and committed team capable of generating impactful results. Our chemical sensors contribute to improving health, the environment, and sustainability. Watching these young researchers develop, grow, and become capable of bringing challenging ideas to life, as well as generating useful and applied knowledge, are my greatest achievements.
Finally, as we close this interview, what message or thoughts would you like to share with the readers of the EuChemS Magazine?
MC: Chemistry is a key discipline for addressing major global challenges, from the energy transition to environmental sustainability and health. I encourage scientists to stay curious, creative, and committed to excellence. Open collaboration, support for young talent, and diversity are essential towards impactful innovations. By sharing knowledge and developing ideas together, we can drive progress that improves both the lives of people and the planet.
