Gold Nanoparticle-Mediated Transfection of Mammalian Cells
Abstract
Mixed monolayer protected gold clusters (MMPCs) functionalized with quaternary ammonium chains efficiently transfect mammalian cell cultures, as determined through beta-galactosidase transfer and activity. The success of these transfection assemblies depended on several variables, including the ratio of DNA to nanoparticle during the incubation period, the number of charged substituents in the monolayer core, and the hydrophobic packing surrounding these amines. Complexes of MMPCs and plasmid DNA formed at w/w ratios of 30 were most effective in promoting transfection of 293T cells in the presence of 10% serum and 100 microM chloroquine. The most efficient nanoparticle studied (MMPC 7) was approximately 8-fold more effective than 60 kDa polyethylenimine, a widely used transfection agent.

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.
