New Antimicrobial Materials Based on Polymers With Nanostructured Surface Modified by Organic Fullerene[60] Derivatives

PLASMA PROCESSES AND POLYMERS, Issue S1 2009
Vera M. Ellinson
Abstract In the present work, the surface of natural and artificial polymers was modified by plasma treatment using reactive gases mixture, ion-beam-induced deposition of , -C:H films and organic C60 derivatives deposition. The study of prepared biomaterials with nanostructured surface was carried out by means of atomic force microscopy, X-ray photoelectron spectroscopy, contact angle measurement and surface energy calculation. The investigation of antimicrobial activity of the materials was carried out by application method in relation to Gram-positive (Staphylococcus aureus ATCC 29213) and Gram-negative (Escherichia coli ATCC 54383 and Pseudomonas aeruginosa ATCC 27853) microorganisms and fungi (Candida albicans).

Abstract New light-activated antimicrobial materials with a potentially wide range of possible uses in civilian settings were synthesized by the grafting of protoporphyrin IX and zinc protoporphyrin IX to nylon fibers. These fibers were shown to be active against Staphylococcus aureus at light exposures of 10,000 lux and greater and against Escherichia coli at 60,000 lux. They were ineffective against both strains in the absence of light. At 40,000 lux, these fibers showed increased antimicrobial activity against S. aureus with increasing exposure time. © 2003 Wiley Periodicals, Inc.

Grafting of light-activated antimicrobial materials to nylon films

JOURNAL OF POLYMER SCIENCE (IN TWO SECTIONS), Issue 1 2003
Jennifer Sherrill
Abstract Protoporphyrin IX and zinc protoporphyrin IX were grafted to the surface of nylon-6,6 films via an ethylene diamine bridge and a poly(acrylic acid) (PAA) scaffold. X-ray photoelectron spectroscopy showed that approximately 57% of the nylon surface was covered by PAA and approximately 6% of the carboxylic acid groups in PAA were grafted to the ethylene diamine derivative of protoporphyrin IX or its zinc salt. © 2002 Wiley Periodicals, Inc.
