Concurrently, there is rising market demand for plas-
tic products treated with antimicrobial additives for
applications in packaging, automotive, consumer goods,
medical and healthcare, building and construction, sport-
ing goods, and electronics markets.
To reduce the incidence of device-associated infections,
antimicrobial technologies have been utilized in a variety
of ways ranging from bulk-imbedded additives to sur-
face grafting techniques.[13,14] In particular, silver-based
additive technologies are frequently explored for
healthcare applications due to their favorable toxicological
profiles and broader regulatory approvals, while silver
nanoparticles with controlled, long-term release profiles
continue to be a very active and promising area of biomedi-
cal research.[15-19] In textile segments such as sports active-
wear, biocides are used to prevent the growth of odor-
causing bacteria from perspiration.[20,21] Additionally,
high-end recreational products such as boats utilize bio-
cides to preserve the aesthetics of PVC products used for
seat covers since bacterial growth may lead to pink staining
caused by specific bacterial metabolites.[22,23] With respect
to the mechanism of action, many antimicrobial products
work by attacking enzymes common to a variety of
microbes, interfering with membrane transport processes
(e.g., importing environmental copper into the cells) as
well as interfering with iron metabolism pathways.[24,25]
Herein, an assortment of both rigid and flexible resins/
compounds will be evaluated for susceptibility to determine
whether particular resin chemistries or compounds are
inherently vulnerable to microbial growth and subsequent
degradation or other deleterious effects.
