“…Yoon and co-workers prepared block copolymers of polystyrene-bpoly(4-vinyl pyridine) and random copolymers of poly(styrene-r-4-vinyl pyridine), both bearing 4-vinyl pyridinium units as the cationic groups. 44 Compared with their random analogs, the block copolymers allow for better accumulation of the cationic groups. As a result, the block polymers display better antibacterial activity against Pseudomonas aeruginosa and S. aureus than the random polymers.…”

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.

“…After the modification of particles, the physical and chemical properties of the particles change and can have great potential as advanced materials for various applications. The prepared materials bearing a positive charge on the nitrogen atom such as on the pyridine or in the ring generate intriguing physical and chemical properties for various applications in electrochemistry [3], battery [4], catalyst [5,6], drug and dye delivery [7], absorption [8,9], and may possess antimicrobial properties [10] and so on.…”

“…These researchers also synthesized insoluble crosslinked pyridinium-type polymers, 26, whose extent of quaternization was measured by a combination of nonaqueous titration and elemental analysis [93]. Block and random copolymer versions of styrene/quaternized vinyl pyridine were compared by Yoon and coworkers [94]. Interestingly, they observed that the block copolymer showed superior activity over the random analogue and posited that the content of quaternized vinyl pyridine units at the polymer/solution interface is higher for the block copolymer.…”

Infectious disease is a critically important global healthcare issue. In the U.S. alone there are 2 million new cases of hospital-acquired infections annually leading to 90,000 deaths and 5 billion dollars of added healthcare costs. Couple these numbers with the appearance of new antibiotic resistant bacterial strains and the increasing occurrences of community-type outbreaks, and clearly this is an important problem. Our review attempts to bridge the research areas of natural host defense peptides (HDPs), a component of the innate immune system, and biocidal cationic polymers. Recently discovered peptidomimetics and other synthetic mimics of HDPs, that can be short oligomers as well as polymeric macromolecules, provide a unique link between these two areas. An emerging class of these mimics are the facially amphiphilic polymers that aim to emulate the physicochemical properties of HDPs but take advantage of the synthetic ease of polymers. These mimics have been designed with antimicrobial activity and, importantly, selectivity that rivals natural HDPs. In addition to providing some perspective on HDPs, selective mimics, and biocidal polymers, focus is given to the arsenal of biophysical techniques available to study their mode of action and interactions with phospholipid membranes. The issue of lipid type is highlighted and the important role of negative curvature lipids is illustrated. Finally, materials applications (for instance, in the development of permanently antibacterial surfaces) are discussed as this is an important part of controlling the spread of infectious disease.
