Immunological properties of engineered nanomaterials

Dobrovolskaia, Marina A., McNeil, Scott E.·2007·Nature Nanotechnology

Abstract

Most research on the toxicology of nanomaterials has focused on the effects of nanoparticles that enter the body accidentally. There has been much less research on the toxicology of nanoparticles that are used for biomedical applications, such as drug delivery or imaging, in which the nanoparticles are deliberately placed in the body. Moreover, there are no harmonized standards for assessing the toxicity of nanoparticles to the immune system (immunotoxicity). Here we review recent research on immunotoxicity, along with data on a range of nanotechnology-based drugs that are at different stages in the approval process. Research shows that nanoparticles can stimulate and/or suppress the immune responses, and that their compatibility with the immune system is largely determined by their surface chemistry. Modifying these factors can significantly reduce the immunotoxicity of nanoparticles and make them useful platforms for drug delivery.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • Properties such as size, surface charge, hydrophobicity/hydrophilicity, and steric effects of particle coating influence compatibility of nanoparticles with immune system.

    “Additionally, the properties such as size, surface charge, hydrophobicity/hydrophilicity, and the steric effects of particle coating have influence on the compatibility of nanoparticles with the immune system [147–150].”
  • Formation of specific antibodies against nanoparticles may affect efficacy and safety of nanoparticle-based therapeutics.

    “It is worth noting that formation of specific antibodies against nanoparticles may affect the efficacy and the safety of nanoparticle-based therapeutics [149, 150].”

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.
