Synthesis of vanadium oxide nanoplate for electrochemical detection of amaranth in food samples

Amaranth dye is an organic compound largely used in the food and beverage industries with potential toxicity effects on humans. In this paper, a new electrochemical sensor for determination of amaranth foods was reported, where kind V2O5 nanoplate (V2O5-NPs) employed as electrode modifying materials. The modified enhanced its signal obviously exhibited wider linear response ranging from 0.1-270.0 µM low detection limit 0.04 ± 0.001 (3Sb/m). This work offers route developing sensors colorant additives other hazardous components foods.
