Journal ArticleDOI
Permanent, non-leaching antibacterial surfaces—2: How high density cationic surfaces kill bacterial cells
Hironobu Murata,Richard R. Koepsel,Krzysztof Matyjaszewski,Krzysztof Matyjaszewski,Alan J. Russell +4 more
TL;DR: The results indicate that surface charge density, is a critical element in designing a surface for maximum kill efficiency and the relevance of this finding to the mechanism of action is discussed.
Journal ArticleDOI
Permanent, nonleaching antibacterial surfaces. 1. Synthesis by atom transfer radical polymerization.
Sang Beom Lee,Richard R. Koepsel,Scott W. Morley,Krzysztof Matyjaszewski,Yujie Sun,Alan J. Russell +5 more
TL;DR: The permanence of the antimicrobial activity was demonstrated through repeated use of a modified glass without significant loss of activity and Atomic force microscopic imaging of cells on modified glass surfaces supports this hypothesis.
Journal ArticleDOI
Antibacterial polypropylene via surface-initiated atom transfer radical polymerization.
TL;DR: Polypropylene (PP) coated by a non-leachable biocide was prepared by chemically attaching poly(quaternary ammonium) (PQA) to the surface of PP and the surface grafted with relatively high MW polymers showed almost 100% killing efficiency.
Journal ArticleDOI
Nonleaching antibacterial glass surfaces via "Grafting Onto": the effect of the number of quaternary ammonium groups on biocidal activity.
Jinyu Huang,Richard R. Koepsel,Hironobu Murata,Wei Wu,Sang Beom Lee,Tomasz Kowalewski,Alan J. Russell,Krzysztof Matyjaszewski +7 more
TL;DR: Antimicrobial surfaces prepared using the "grafting onto" technique resulted in small patches of highly concentrated polymer that appear to increase the killing efficiency as compared to surfaces prepared by grafting onto with the same average polymer density but with a uniform distribution.
Journal ArticleDOI
Biomaterials for mediation of chemical and biological warfare agents.
TL;DR: This review discusses the major chemical and biological warfare agents, decontamination methods, and biomaterials that have potential for the preparation ofDecontamination wipes, gas filters, column packings, protective wear, and self-decontaminating paints and coatings.
