The use of silver nanoparticles (Ag NPs) in consumer products, such as sportswear, washing machines and medical devices, hasrapidly increased on the market due to their antibacterial properties. An important source of Ag NPs to the environment is fromcleaning of Ag NP impregnated textile, where they come in contact with surfactants in the laundry circle (notably anionic sodiumdodecylbenzenesulfonate (LAS), cationic dodecyltrimethylammoniumchloride (DTAC) and nonionic Berol 266 (Berol)). We havepreviously studied the surfactantAg NP interactions by means of dynamic light scattering, Raman spectroscopy, zeta potential, andQuartz Crystal Microbalanceby, and the results indicate formation of self-assembled surfactant structures in the proximity of Ag NPs.Our interest in using small-angle neutron scattering is to characterize the structure of those self-assembled aggregates formed inpresence of differently charged Ag NPs.
