Oppositely charged nanoparticles precipitate rapidly only at the point of electroneutrality,
wherein their charges are macroscopically compensated. We investigated the aggregation …

Precipitation of oppositely charged entities is a common phenomenon in nature and
laboratories. Precipitation and crystallization of oppositely charged ions are well-studied and …

Mixtures of oppositely charged nanoparticles of various sizes and charge ratios precipitate
only at the point of electroneutrality. This phenomenon specific to the nanoscale and …

Mixtures of oppositely charged nanoparticles (NPs) exhibit anomalous solubility behavior
and precipitate either upon dilution or upon temperature increase. Precipitation is reversible …

Opposites attract (selectively): Oppositely charged nanoparticles characterized by different
size distributions form 3D supracrystals (see figure) only if the distributions overlap. Crystal …

Mixtures of oppositely charged nanoparticles (NPs) precipitate sharply only at the point of
NP electroneutrality. This behavior—reminiscent of the threshold precipitation of inorganic …

Nanoparticles (NPs) are envisaged as both building blocks to form advanced materials [1–3]
and appropriate models to gain insight into condensed-matter physics;[4–7] this is because …

We report a fast and highly reproducible chemical synthesis method for colloidal gold
nanoparticles which are negatively charged in nonpolar solvents and coated with …
