Key Points

This research investigates how charge regulation of macroions affects their interaction behavior in low salt conditions.
Conducted experiments with planar macroions in an electrolyte environment.
Manipulated ion adsorption and dissociation reactions to regulate charge.
Analyzed interactions between chemically identical macroions.
Observed significant symmetry breaking in macroion interactions at low salt concentrations.
Identified reversible changes in charge as a key factor affecting interaction dynamics.
Noted that variations in ion concentration influenced structural arrangements.

Implication

Experiments demonstrate charge regulation impacts symmetry in macroion interactions, suggesting new insights into colloidal behavior.

Abstract

The charge of macroions such as colloids and membranes can often be regulated by reversible ion adsorption or dissociation reactions. When two chemically identical macroions interact across an electrolyte, charge...
