A black aggregation of the GNPs deposited, but the GNRs and GNBs did not aggregate in the solution (Figure ). The GNR samples exhibited small, visible droplets, and GNRs were not included in the droplets. Conversely, the GNBs produced mature droplets, which were larger than those of the other samples. The microscopic images indicated that some parts of the GNBs were incorporated in the droplets (Figures and). To check the droplet likeness of the condensates under each condition, we applied the effects of the additive ions to dissolve them. The driving force of the poly-L-lysine droplets was the electrostatic interaction; thus, the addition of NaCl, an inhibitor of electrostatic interaction, can drive the dissolution of the droplets .
