Development of durable antimicrobial surfaces containing silver- and zinc-ion–exchanged zeolites

The present work involves development of stable antimicrobial materials containing silver- and zinc-ion–exchanged zeolites. Faujasite X and Linde type A zeolites were synthesized, and following ion exchange with Ag+ and Zn++ ions they were found to exhibit antimicrobial effects against bacteria (E. coli, P. aeruginosa, and S. aureus), yeast (C. albicans and C.glabrata), and fungi (A. niger and P. expansum).
