A highly sensitive flow injection chemiluminescence method for myoglobin detection in beef samples based on zinc ion-induced “dragging” of heme iron
We report for the first time that zinc ions (Zn<sup>2+</sup>) significantly enhance the chemiluminescence (CL) signal of the luminol-hydrogen peroxide (luminol-H<sub>2</sub>O<sub>2</sub>) system by "dragging" heme iron out of myoglobin (Mb). Integrating this with myoglobin aptamer (Mb aptamer) specific recognition enables sensitive and specific quantification of Mb content in beef samples.
