Abstract
Understanding nanoparticle (NP) translocation through complex cellular membranes is required for pre-evaluating their toxicity. Silver (Ag) is a common material, extensively applied in NP form for its apparent anti-bacterial properties. While so widely available, data about their interaction with lipid membranes, particularly the role of size and surface functionalization in membrane binding, is relatively scarce. As a first step, we performed all-atom biased and unbiased molecular dynamic simulations for bare Ag NPs for three sizes (1/3/5 nm diameter) with a complex membrane of DPPC:DOPC:POPC:Chol in 5:2:2:1 representing model lung membrane.
