We investigated the size-dependence of silver nanoparticle (NP) interactions with L-phosphatidylcholine (PC) supported lipid bilayers (SLBs) when equilibrated with 20 mg/L of four NOM analogs: Suwannee River Humic Acid Standard II (SRHA), Suwannee River Fulvic Acid Standard II (SRFA), Elliott Soil Humic Acid Standard IV (ESHA) and Leonardite Humic Acid Standard (LHAS). We isolated the effective interaction of 20 nm, 40 nm, and 50 nm silver NPs at a concentration of 1E10 NP/mL using quartz crystal microbalance with dissipation monitoring (QCM-D). The study aimed to develop a mechanistic model for nanosilver interactions with SLBs and inform regulators of the health risks associated with the influx and accumulation of NPs in the environment.
