Overview
This paper reports the hydrothermal synthesis of three-dimensional NiCo2O4 nanostructures on nickel foam for use as a glucose sensor electrode. Cobalt and nickel are structural components of the spinel oxide NiCo2O4; they are not measured as environmental or food contaminants. The paper is a materials science and electrochemistry study without food occurrence data.
This source is filed for completeness as a deposit item. It does not contribute to cobalt occurrence evidence in food or personal care product matrices.
Key numbers
Glucose linear detection range: 0.005 to 15 mM. Sensitivity: 91.34 mV/decade. Limit of quantification: 1.9 × 10^-3 mM. Response time: less than 10 seconds.
Implications for the wiki
None for food occurrence or toxicology. This paper is out of scope for heavy metal food safety evidence. It demonstrates cobalt’s utility in electrode materials but provides no data relevant to dietary exposure, cosmetic contamination, or food-safety regulation.
