Due to their antimicrobial properties, silver nanomaterials (AgNMs) are increasing found in consumer products. The growing use of AgNMs will result in increased entrance into the environment upon their disposal. To date, several studies have examined the transformations of AgNMs and AgNM containing consumer goods after their disposal, though little work has been done to ensure that these transformations were caused during exposure rather than during the extraction process. The aim of this work is to develop and evaluate methodologies for extracting AgNMs and AgNM containing textiles from synthetic human and environmental exposure media, which have been verified to not induce chemical and physical transformations. Model AgNM containing textiles and commercially available wound dressing were examined in this work. Methods for extraction will include ultrafiltration, centrifugation, and vacuum drying. Both pristine and extracted materials were analyzed quantitatively and qualitatively using analytical techniques including scanning electron microscopy with energy dispersive X-ray spectroscopy, X-ray diffraction, X-ray photoelectron spectroscopy, inductively coupled plasma mass spectrometry, UV-visible spectroscopy, dynamic light scattering, and silver ion selective electrode.<br/>
