Recent Advances in Electroanalysis of Vitamins

Vitamins are a chemically heterogeneous group of compounds known as essential for the normal functioning of the organic metabolism. Their decrease in humans can lead to several diseases and not being produced by the body, they need to be obtained from dietary sources or supplements. For these reasons, their determination in food, pharmaceutical and clinical samples is crucial. This article reviews key advances in electrochemical measurements of vitamins over the past decade. Particular attention is given to papers proving applicability to real samples analysis. The technical features of the proposed sensors are presented and discussed along with their analytical performances. Future trends and challenges are also addressed.
