FOREWORD This NIST special publication (SP) is one in a series of NIST SPs that address research needs articulated in the National Nanotechnology Initiative (NNI) Environmental, Health, and Safety Research Strategy published in 2011 . This Strategy identified a Nanomaterial Measurement Infrastructure (NMI) as essential for science-based risk assessment and risk management of nanotechnology-enabled products as pertaining to human health, exposure, and the environment. NIST was identified as the lead federal agency in the NMI core research area of the Strategy; this research area includes measurement tools for the detection and characterization of nanotechnology-enabled products. Nano-silver in textiles, the focus of this SP, is a consumer product of great interest for nanotechnology environmental, health, and safety (nano-EHS) research and for product regulation. The protocol presented in this SP describes a strategy for developing a validation sample (a positive control) known to contain nanoscale silver particles loaded onto the surface of a cotton thread. This validation sample can be used to test the capabilities of various analytical methods to characterize nano-silver in textiles. Updates to this protocol may be released in the future.
