Facially amphiphilic polyionene biocidal polymers derived from lithocholic acid [PDF]

Bioactive Materials, 2018
Bacterial infections have become a global issue that requires urgent attention, particularly regarding to emergence of multidrug resistant bacteria. We developed quaternary amine-containing antimicrobial poly(bile acid)s that contain a hydrophobic core ...

Biocidal Polymers: A Mechanistic Overview [PDF]

Polymer Reviews, 2016
Bacterial fouling on surfaces is considered a major problem in modern society. Conventional methods to prevent biofilm formation often have little effect and may induce further contamination. In response to this challenge, biocidal polymers have been designed and applied as an alternative approach to kill or inhibit bacteria and prevent the formation ...

Evaluation of the release characteristics of covalently attached or electrostatically bound biocidal polymers utilizing SERS and UV-Vis absorption

eXPRESS Polymer Letters, 2016
In this work, biocidal polymers with antimicrobial quaternized ammonium groups introduced in the polymer biocidal chains either through covalent attachment or electrostatic interaction have been separately incorporated in a poly (methyl methacrylate ...

Factors Determining the Antimicrobial Effectiveness of Chitosan: A Critical Analysis of the Impact of Molecular Weight and Degree of Deacetylation [PDF]

Molecules
Despite chitosan’s proven biocidal potential, there is a lack of consensus regarding the influence of its key physicochemical parameters, degree of deacetylation (DD) and molecular weight (MW), on its antimicrobial efficacy.

A New Sustainable Approach to Antibiotic Resistance: Development of bis-Quaternary Ammonium Salts From 2,4,6-Trichloro-1,3,5-Triazine. [PDF]

ChemMedChem
Antibiotics improved human life, but bacterial resistance makes surfaces and packaging disinfection critical. Quaternary ammonium salts (QAS) represent a possible alternative. In this work, new bis‐cationic QAS from 2,4,6‐trichloro‐1,3,5‐triazine (bis‐TQAS) were synthesized, showing excellent inhibition against Klebsiella pneumoniae, Escherichia coli ...

Beyond Bactericidal: Plasma Surface Engineering to Defeat Food Matrix-Conditioning Layers. [PDF]

Compr Rev Food Sci Food Saf
ABSTRACT The persistence of foodborne pathogens on industrial food contact surfaces continues to challenge global food safety despite advances in sanitation technologies. A central limitation of current antimicrobial strategies lies in their validation under simplified laboratory conditions that overlook the physicochemically driven formation of food ...

Biocidal polymers (I): Preparation and biological activity of some novel biocidal polymers based on uramil and its azo-dyes

Reactive and Functional Polymers, 2008
Biocidal polymers were prepared by reacting uramil with polyacrylonitrile and polyethylacrylate, and also by co-polymerizing heterocyclic monomers based on uramil azo-dyes with tolylene-2,6-diisocyanate and toluene-2,4-diisocyanate. The prepared polymers were converted to their quaternary salts and N-halamine forms.
