A facile method to fabricate a mesoporous poly(ethylene-co-vinyl alcohol) (EVOH) monolith captured with silver nanoparticles (AgNPs) was developed. The formation of AgNPs and the monolith was in a one-pot process. The obtained monolith demonstrated ultrasensitive surface-enhanced Raman spectroscopy (SERS) responses.
