“…Apart from the ammonium groups, the iminium structures are another common form of the cationic groups, like pyridinium, [22][23][24][25] imidazolium 26,27 and guanidinium salts. 28,29 The difference between ammonium and iminium groups is that the positive charges of the latter ones are delocalized evenly through the π bonds or aromatic conjugated systems, which may influence their adsorptive ability to membrane.…”

Antimicrobial cationic polymers mainly contain two functional components: the cationic groups and the hydrophobic groups. The antimicrobial activity is influenced by the type, amount, location and distribution of these two components. This review summarizes the designs and syntheses of antimicrobial cationic polymers by controlling the above two factors. It involves the structural designs from primary to secondary structures, from covalent to noncovalent syntheses and from bulk to surface. Furthermore, it will discuss how to advance structural designs toward functional controls for optimizing the antimicrobial performances and biocompatibility of antimicrobial cationic polymers. It is anticipated that this review will provide some guidelines for developing molecular engineering of antimicrobial cationic polymers with tailor-made structures and functions.

Denture stomatitis and fungal infection are commonly found in long-time denture wearer. Ionic liquids have been used as plasticizer and also possess antimicrobial activity. In this study, ionic liquid in form of 1-Decyl-3-methylimidazolium chloride was incorporated into tissue conditioner (GC Soft-liner TM ) to improve antifungal activity. Physical and mechanical properties were evaluated. Compliance was carried out using penetration test according to ISO 10139-1. Weight change, water absorption and solubility were determined by weight measurement. Conventional and nystatin-incorporated tissue conditioner served as controls. Results showed that ionic liquid-incorporated tissue conditioner significantly decreased fungal formation, both in material suspension and on material surface. The penetration depth of all groups tended to reduce over time with no significant difference at each time point. After water immersion, ionic liquid-and nystatin-incorporated tissue conditioner gained weight while conventional group showed weight loss. The percentage of water absorption of conventional group was significantly lower than ionic liquid and nystatin group, while the percentage of water solubility of nystatin group was significantly higher than others. Our work indicated that antifungal ionic liquid-incorporated tissue conditioner met the standard criteria in terms of material compliance. However, further studies including dynamic viscoelastic property are needed before clinical trial or application.
