英文摘要The nanoparticle (nano)-cell membrane interface is one of the most important interactions determining the fate of nanoparticles (NPs So far, there remains a lack of knowledge about the mechanisms governing the nanoparticle-cell membrane interface, especially the impact of ligand exchange, in which molecules on the nanosurface become replaced with components of the cell membrane, resulting in unique interfacial phenomena. Herein, we describe a family of gold nanoparticles (AuNPs) of the same core size (similar to 13 nm core The ligands are categorized according to their molecular weight, charge, and bonding modes (physisorption or chemisorption). Importantly, we found that, depending on the adsorption affinity and size of ligand molecules, physisorbed ligands on the surface of NPs can be exchanged with lipid molecules. At a ligand exchange-dominated interface, the AuNPs typically aggregated into an ordered monolayer in the lipid bilayers, subsequently affecting cell membrane integrity, NP uptake efficiency, and the NP endocytosis pathways. These findings advance our understanding of the underlying mechanisms of the biological effects of nanoparticles from a new point of view and will aid in the design of novel, safe, and effective nanomaterials for biomedicine.
