The surface charge of different types of particles depends on the pH, allowing cationic or anionic surfactants to be selectively adsorbed.
With naturally occurring phosphate and the added cationic charge, this starch is naturally amphoteric.
Basic dye Cationic dyes attracted to the anionic groups on, for example, acrylic copolymers.
The mechanism by which cationic liposomes deliver DNA into the cell is poorly understood.
The LPS also interacts unusually with the cationic cyclic peptide polymyxin (PMB) to enhance rather than suppress pro-inflammatory cytokines (1 ).
