Even though the HORIZON EUROPE “ARGO” project has not yet crossed its execution equator, promising scientific results are already been achieved today. On January 23, 2024, project group members held an online seminar dedicated to the results of the experimental application of silver nanoparticles to the tissue of dental canals. The representative of the Ukrainian-Swedish center “SUMEYA” prof. In his report, Yevhen Kuzenko showed progress in researching the interaction of silver nanoparticles with the tissue of dental canals of human teeth.
