Efficiency of using antibacterial coatings on titanium implants in the treatment of gunshot fractures

Гений oртопедии
Introduction High risk of infectious complications in gunshot wounds remains a pressing issue in military medicine. Analysis of the structure of sanitary losses shows that limb injuries account for 55 % to 81.4 %, with about 35 % of them accompanied by

Disinfection of Water by N-Halamine Biocidal Polymers

Industrial & Engineering Chemistry Research, 1995
Two novel polymers have been tested in a filter application for biocidal efficacy for flowing aqueous solutions of microorganisms. A laboratory water pump was employed in the experiments to provide contact times on the order of 1-2 s/mL. The two polymers are N-chlorinated and N-brominated derivatives of a polystyrene hydantoin.

Preparation of Novel Biocidal N-Halamine Polymers

Journal of Bioactive and Compatible Polymers, 1995
The preparation and biocidal efficacies of eight new N-halamine polymers have been reported. The polymers are in the classes known as dichlorohydantoins, trichlorotriazinediones, and dichloropyrimidinones. They were synthesized from the commercial polymers polystyrene, poly(methyl vinyl ketone), and polymethacrylamide.

New Biocidal N-Halamine-PEG Polymers

Journal of Bioactive and Compatible Polymers, 1998
The synthesis and biocidal efficacies of two PEG-N-halamine polymers were reported. The N-halamines are classified as dichlorohydantoins and chloroimidazolidin-4-ones, which were attached to a methoxy-poly(ethylene glycol) terminated amine. A 1000 ppm solution of each N-halamine polymer was prepared in water and it was demonstrated that Staphylococcus ...

Biocidal Potency of Polymers with Bulky Cations

ACS Macro Letters, 2023
The performance of antimicrobial polymers depends sensitively on the type of cationic species, charge density, and spatial arrangement of cations. Here we report antimicrobial polymers bearing unusually bulky tetraaminophosphonium groups as the source of highly delocalized cationic charge. The bulky cations drastically enhanced the biocidal activity of

A novel biocidal styrenetriazinedione polymer

Polymer, 1996
Abstract Commercial polystyrene has been modified by chemically attaching 6-methyl-1,3,5-triazine-2,4-dione moieties to it in the para position of the aromatic rings. Chlorination of this novel polymer in aqueous base yielded poly(1,3,5-trichloro-6-methyl-6-(4′-vinylphenyl)-1,3,5-triazine-2,4-dione) which functioned as a biocide against the ...

Biocidal polymers active by contact. V. Synthesis of polysiloxanes with biocidal activity

Journal of Applied Polymer Science, 2000
Polysiloxanes with 3-(alkyldimethylammonio)propyl pendant groups were synthesized by quaternization of n-octyldimethylamine or n-dodecyldimethylamine with linear polysiloxanes containing 3-chloropropyl groups and/or 3-bromopropyl groups attached to silicon atoms.
