many years silver has been used as a broad spectrum antimicrobial agent, applied
towards reducing infections of burn victims, water treatment, treating textiles,
among others. With an increasing amount of antibiotic-resistant bacteria, the
utility of silver coatings and treatments are again being recognized as a cost-
effective way to prevent bacterial infections such as for medical implants. This
is especially crucial when surgeries are performed in environments where
sanitation is not ensured.
WSU invention relates to the use of silver coatings on medical implants as a
valuable addition to promote antimicrobial properties such as resistance to
growth of Gram negative bacteria (e.g., Pseudomonas aeruginosa). In an effort to
optimize antimicrobial effectiveness and keep human cell-toxicity to a minimum,
WSU inventors have experimented with various coating parameters and observed
their effects on the utility of silver coating on SIGN stainless steel
deposited implants offer to reduce growth of infection due to biofilm formation
and aid fracture healing.
