To elucidate plasma-liquid interactions, the effect of silver nitrate aqueous droplet evaporation on precursor formation was evaluated using 1D numerical analysis. A model was developed using continuity and heat conduction equations to replicate droplet shrinkage associated with charged particle influx . The results showed that the droplet radius decreased from 52.4 µm to 38.9 µm over 0.1 s, and an increase in the production of silver nanoparticle precursors was confirmed due to enhanced reaction rates resulting from silver ion concentration near the liquid surface.
