RELIANCE project showcased its promising research at the recent Bioanalytical Chemistry Days held in Rome, Italy, from April 7th to 9th, 2025. A poster titled “Origami paper-based biosensor to SARS CoV-2 on the surface” presented significant progress in the project's efforts to develop innovative biosensing technologies.

The poster was a collaborative effort between RELIANCE partners from the Department of Chemical Science and Technologies at the University of Rome Tor Vergata (UNITOV) and the Defense Institute for Biomedical Sciences (ISBD). It detailed an adaptation of the project's paper origami electrochemical sensor for rapid and convenient detection of the SARS-CoV-2 virus on surfaces.

A key feature of the presented method is the utilization of magnetic beads as a support for the sandwich-type immunological chain. This approach leverages the high surface-to-volume ratio of the magnetic beads, enabling the loading of a substantial quantity of antibodies and consequently enhancing the sensitivity of the assay.

The Bioanalytical Chemistry Days 2025 took place at the distinguished Palazzetto Mattei, the headquarters of the Italian Geographical Society in Rome. The event brought together approximately 100 participants for a comprehensive program that included oral presentations, concise flash talks, expert insights, and a diverse collection of scientific posters. A remarkable moment was an engaging round table discussion with prominent experts from the medical, nutritional and forensic sectors, alongside significant contributions’ award recognition. The event served as a valuable forum for exchanging knowledge and fostering collaboration within the bioanalytical science community.
