Abstract

This paper reviews the recent development of electrochemical sensors for the detection of vitamins over the past three years. Vitamins present in natural foodstuffs are a group of organic compounds that are indispensable to maintain human health. While they are only present in minute amounts, they still play a significant role in healthy metabolism. The deficiency of vitamins in the human body often leads to numerous diseases. Because the human body cannot synthesize most vitamins, it is necessary to obtain them from dietary sources. For these reasons, the detection of vitamins has gained widespread attention in recent years. As it is well known, almost all vitamins are electrochemically active. Based on the electrochemical oxidation or reduction reaction of the vitamins in an electrolyte, electrochemical sensors can obtain the concentration of the vitamins by measurement of the current at the working electrode. Electrochemical sensors for detecting water-soluble vitamins, such as vitamin B 1, vitamin B 2, vitamin B 6, vitamin B 9, vitamin B 12, and vitamin C are discussed in detail. A comprehensive overview of electrochemical sensors for detecting fat-soluble vitamins, such as vitamin A, vitamin D, vitamin E, and vitamin K, is also provided. Furthermore, the strategies employed and the performance of the electrochemical sensors for detecting vitamins are described. Finally, current challenges and future prospects of electrochemical sensors for the detection of vitamins are discussed.

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.
