Antimicrobial Polymer nanostructures: synthetic route, mechanism of action and perspective.
Advances in colloid and interface science, 2013Co-Authors: Jooyoung Song, Jyongsik JangAbstract:Protection against bacterial infections is an important research field in modern society. Antimicrobial Polymers have received considerable attention as next-generation biocides because they represent an ecologically friendly approach that does not promote resistance. In the last decade, many authors have reported the development of nano-sized Antimicrobial Polymers with enhanced bactericidal performance by increasing the active-area of biocides. This review presents several suitable methods of synthesis of Antimicrobial Polymer nanomaterials with various shapes, including a nanosphere and fibrous and tubular structures. We also discuss the Antimicrobial mechanisms of these Polymers. In addition, Antimicrobial Polymer thin films, which can inhibit bacterial adhesion, are introduced briefly with examples. Our aim is to present synthetic routes and formation mechanisms of various Antimicrobial Polymer nanostructures.

Photocatalytic Antibacterial Capabilities of TiO2−Biocidal Polymer Nanocomposites Synthesized by a Surface-Initiated PhotoPolymerization
Environmental Science & Technology, 2010Co-Authors: Hyeyoung Kong, Jooyoung Song, Jyongsik JangAbstract:Novel biocidal Polymer-functionalized TiO2 nanoparticles were prepared by surface-initiated photoPolymerization using titania as an initiator. Vinyl monomer mixtures of nontoxic secondary amine-containing biocidal 2-(tert-butylamino)ethyl methacrylate and antifouling ethylene glycol dimethacrylate were used for the Antimicrobial Polymer shell. It was shown that the synthesized TiO2/poly[2-(tert-butylamino)ethyl methacrylate-co-ethylene glycol dimethacrylate] core/shell nanoparticles had enhanced photocatalytic antibacterial properties compared to the pristine TiO2 nanoparticles due to the combined antibacterial activities of light-driven anti-infective TiO2 core and biocidal Polymer shell. In the dark condition, the TiO2/biocidal Polymer nanoparticles exhibited high Antimicrobial efficiency (95.7%) against gram-positive S. aureus. Furthermore, during UV irradiation, the TiO2/biocidal Polymer showed improved inhibition of bacterial growth against gram-negative E. coli and gram-positive S. aureus in compari...

Antifouling and Antimicrobial Polymer Membranes Based on Bioinspired Polydopamine and Strong Hydrogen-Bonded Poly(N-vinyl pyrrolidone)
ACS Applied Materials & Interfaces, 2013Co-Authors: Jinhong Jiang, Hong-tao Zhang, You-yi XuAbstract:A facile and versatile approach for the preparation of antifouling and Antimicrobial Polymer membranes has been developed on the basis of bioinspired polydopamine (PDA) in this work. It is well-known that a tightly adherent PDA layer can be generated over a wide range of material surfaces through a simple dip-coating process in dopamine aqueous solution. The resulting PDA coating is prone to be further surface-tailored and functionalized via secondary treatments because of its robust reactivity. Herein, a typical hydrophobic polypropylene (PP) porous membrane was first coated with a PDA layer and then further modified by poly(N-vinyl pyrrolidone) (PVP) via multiple hydrogen-bonding interactions between PVP and PDA. Data of water contact angle measurements showed that hydrophilicity and wettability of the membranes were significantly improved after introducing PDA and PVP layers. Both permeation fluxes and antifouling properties of the modified membranes were enhanced as evaluated in oil/water emulsion fil...

Antifouling and Antimicrobial Polymer Membranes Based on Bioinspired Polydopamine and Strong Hydrogen-Bonded Poly(N-vinyl pyrrolidone)
ACS applied materials & interfaces, 2013Co-Authors: Jinhong Jiang, Hong-tao Zhang, Liping Zhu, Li-jing Zhu, Bao-ku ZhuAbstract:A facile and versatile approach for the preparation of antifouling and Antimicrobial Polymer membranes has been developed on the basis of bioinspired polydopamine (PDA) in this work.

Both permeation fluxes and antifouling properties of the modified membranes were enhanced as evaluated in oil/water emulsion filtration, protein filtration, and adsorption tests. Furthermore, the modified membranes showed remarkable Antimicrobial activity after iodine complexation with the PVP layer. The PVP layer immobilized on the membrane had satisfying long-term stability and durability because of the strong noncovalent forces between PVP and PDA coating. The strategy of material surface modification reported here is substrate-independent, and applicable to a broad range of materials and geometries, which allows effective development of materials with novel functional coatings based on the mussel-inspired surface chemistry.
