Controlled Photoinitiated Release of Nitric Oxide from Polymer Films Containing S-Nitroso-N-acetyl-dl-penicillamine Derivatized Fumed Silica Filler

Frost, Megan C., Meyerhoff, Mark E.·2004·Journal of the American Chemical Society

Abstract

This report describes the first hydrophobic nitric oxide (NO)-releasing material that utilizes light as an external on/off trigger to control the flux of NO generated from cured polymer films. Fumed silica polymer filler particles were derivatized with S-nitroso-N-acetyl-dl-penicillamine and blended into the center layer of trilayer silicone rubber films. Nitric oxide is generated upon irradiation with light, and fluxes increase with increasing power of incident light. The ability to precisely control NO generation from this material has the potential to answer fundamental questions about the levels of NO needed to achieve desired therapeutic affects in different biomedical applications.

Statistics

Recomputing p-values needs the paper’s full text.

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?

  • SR films containing SNAC-FS or SNAP-FS in the middle layer do not release NO upon exposure to copper ions or ascorbate in PBS because the high hydrophobicity of SR blocks contact between buffer and RSNOs.

    “However, the SR films containing SNAC-FS or SNAP-FS in the middle layer do not release NO upon exposure to copper ions or ascorbate in PBS solution because the very high hydrophobicity of the SR blocks the contact between the buffer and the RSNOs.199”

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.
