Abstract

Superparamagnetic iron oxide nanoparticles (SPIONs) are increasingly used in medical applications, such as targeting delivery and imaging. In the future, patients are more likely to be exposed to pharmaceutical products containing such particles. The study of toxicity of SPIONs has become of great importance in recent years, although the published data in this arena is limited. The aim of the present work is to investigate the cytotoxicity of SPIONs and the effect of the particles on the cell medium components. For this purpose, uncoated and polyvinyl alcohol (PVA) coated SPIONs with narrow size distribution were synthesized via a well-known coprecipitation method. The mouse fibroblast cell line L929 was exposed to SPIONs to probe the toxicity of magnetic nanoparticles during the bio application. Changes to the cell medium caused by SPIONs were analyzed with zeta potential measurements, ultraviolet visible spectroscopy (UV/vis) and the 3-[4,5-dimethylthiazol-2yl]-2,5-diphenyltetrazolium bromide (MTT) assay. It is observed that gas vesicles are formed in SPION-treated cells. Toxicity is conventionally explained by changes in the DMEM's pH and composition due to the tendency of SPIONs to interact with biomolecules. A new procedure is proposed to examine the in vitro toxicity of nanoparticles in a more rigorous manner, which gives an improvement in the relationship between in vivo and in vitro toxicity studies.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In vitro, upon prolonged incubation, surface-coated SPION are typically nontoxic at iron concentrations up to 10 μg/ml, while slight cytotoxicity is seen at 100 μg/ml.

    “In vitro, upon prolonged incubation, surface-coated SPION are typically nontoxic at iron concentration up to and 10 μg/ml, while slight cytotoxicity is seen at 100 μg/ml.”
  • SPION toxicity depends on dosing, exposure time, nature of the coating material, hydrodynamic diameter of the particle and SPION-protein interactions.

    “In general, SPION toxicity depends on a variety of factors, including - besides dosing and exposure time - also the nature of the coating material, the hydrodynamic diameter of the particle and SPION-protein interactions [119–122].”

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.
