Nearly 30% of all nanotechnology-based commercial products contain silver nanoparticles (nanosilver) due to their remarkable odor-resistant and antimicrobial properties, with cotton textiles as a prominent category. With the projected increase in demand for these products, a simple and quick method for quantifying nanosilver in these materials is required. Current analytical techniques require lack specificity (UV-vis), have complicated sample preparation (ICP-OES), or require expensive equipment (scanning tunneling microscopy). Herein, a facile, selective and sensitive approach for quantifying nanosilver is applied to nanosilver-dispersed cotton textiles.
