Silver Nanoparticle Release and Characterisation
topic
Silver nanoparticle characterisation in antimicrobial textiles combines SP-ICP-MS for particle size distribution and number concentration measurement, TEM-EDX for morphological and compositional analysis, and dynamic light scattering for hydrodynamic diameter; wash release testing quantifies dissolved silver ion and nanoparticle fractions released into laundry water using ultrafiltration membrane separation before ICP-MS analysis.
Role
Characterises the ecotoxicological release profile of silver nanoparticle antimicrobial textile treatments for regulatory risk assessment under REACH nanomaterial provisions, quantifying the proportion of silver released as bioavailable ionic versus particulate nanosilver forms during domestic laundering that reach aquatic environments via wastewater treatment plant effluents.
