This paper grows bismuth nanoparticles on electrospun carbon nanofibers and uses them on a screen-printed electrode to detect nitrite in food and environmental samples. Bismuth is the catalyst on the electrode; the analyte is nitrite.
Key numbers
This paper reports no numerical findings relevant to bismuth exposure.
Methods (brief)
The electrode was characterized and applied to nitrite detection in a drop of solution; the authors report a range of 0.1 to 800 µM and a detection limit of 19 nM for nitrite (abstract).
Evidence fitness
This is a materials or analytical chemistry paper in which bismuth is a component of an engineered material. It does not support dietary exposure or toxicity claims for bismuth, and no bismuth was measured in food, water, feed, soil or human or animal tissue.
Limitations
Nitrite results are outside the scope of this page.
