Citizen science and analytical chemistry. Oxymoron or harmony of meaning?

• Citizens meets analytical chemistry: a bridge for growing. • Low cost, eco-friendly, and wearable devices. • Health and environmental monitoring. • 3D printing and smartphone as tools for inclusivity in science. Citizen science is rapidly emerging as a transformative force in analytical chemistry by opening research participation to non-specialists and expanding where and how data can be collected. This report explores how recent technological advances have made analytical tools simpler, smaller, and more affordable. These developments have enabled citizens and students to be engaged directly in environmental monitoring, food-quality assessment, and educational activities, often producing data comparable to those generated in laboratories. In addition, several emerging prototypes have been purposefully designed with citizen use in mind, anticipating future applications in participatory science. The discussion also addresses areas where citizen science could play a growing role, including biomedical and forensic analysis, while recognizing challenges related to data reliability, ethics, and validation. Overall, this report highlights how accessible technologies, supported by artificial intelligence and digital communication, are transforming analytical chemistry into a more inclusive and collaborative discipline, connecting scientific research with everyday life.
