Antibacterial properties of nitric oxide–releasing sol‐gels
Abstract
The antibacterial characteristics of nitric oxide (NO)‐releasing sol‐gel coatings are described. The NO release from these surfaces is steady over short periods (≈1 h) and measurable over several days. The ability of NO to prevent bacterial adhesion is evaluated by exposing controls and NO‐releasing sol‐gels to ≈10 8 colony‐forming units (cfu)/mL saline suspensions of Pseudomonas aeruginosa. Pseudomonas aeruginosa adhesion to sol‐gel controls varies depending on the sol‐gel formulation. Sol‐gel surfaces capable of NO release decrease bacterial adhesion by 30% to 95% relative to controls. The contact angle measurements of control and NO‐releasing surfaces are similar, supporting NO's action as an antibacterial agent against bacterial adhesion. © 2003 Wiley Periodicals, Inc.

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.
