Agenda, Presentations and Posters of the 28^th Conference

28^th ETH Nanoparticles Conference (NPC-25), June 16-19, 2025

The ETH Nanoparticles Conference (NPC) in 2025 was organized as an in-person conference under the auspice of the Swiss Chemical Society (see website of the conference, https://npc25.scg.ch).

It served as an interdisciplinary platform for expert discussions on all aspects of nanoparticles, freshly emitted from various sources, aged in ambient air, technical mitigation aspects, impact of particles on health, environment and climate and particle legislation. The conference brought together representatives from research, industry and legislation.
