Droplet-on-demand mass spectrometry reveals curvature-dependent interfacial reactivity in aqueous microdroplets

Proceedings of the National Academy of Sciences, Volume 122, Issue 50, December 2025. <br/>SignificanceChemical reactions in aqueous microdroplets are known to proceed at remarkably accelerated rates, yet the decisive factors governing these rate enhancements remain elusive. We introduce a droplet-on-demand mass spectrometry platform that …
