Polycationic starches

The significant antibacterial effect of the polycationic derivatives of sucrose is not unexpected. Antibacterial (and antifungal) characteristics are noted for even simple cationic derivatives of lipophilic materials, increasing as the density of charge and tethered sites of charge increase. Even greater antibacterial activity is noted for polycationic derivatives of oligosaccharide species such as soluble starch.
