Wide Varieties of Cationic Nanoparticles Induce Defects in Supported Lipid Bilayers
Open accessAbstract
Nanoparticles with widely varying physical properties and origins (spherical versus irregular, synthetic versus biological, organic versus inorganic, flexible versus rigid, small versus large) have been previously noted to translocate across the cell plasma membrane. We have employed atomic force microscopy to determine if the physical disruption of lipid membranes, formation of holes and/or thinned regions, is a common mechanism of interaction between these nanoparticles and lipids. It was found that a wide variety of nanoparticles, including a cell penetrating peptide (MSI-78), a protein (TAT), polycationic polymers (PAMAM dendrimers, pentanol-core PAMAM dendrons, polyethyleneimine, and diethylaminoethyl-dextran), and two inorganic particles (Au-NH2, SiO2-NH2), can induce disruption, including the formation of holes, membrane thinning, and/or membrane erosion, in supported lipid bilayers.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
