Abstract

The present invention provides hygienic absorbent articles, such as feminine sanitary napkins, tampons and disposable diapers, having antimicrobial activity that can minimize odors caused by body fluids. The articles of the invention include an absorbent member such as an elongated absorbent portion or pad that contains an antibacterial amount of substantially immobilized nanosilver particles or particles containing silver ions, preferably encased in a granule of a soluble carrier such as dextran, and the like, or a water-insoluble, but water- swellable superabsorbent polymer (SAP).
