Design and fabrication of a preconcentration-free Mg-doped hydroxyapatite based electrochemical sensor for simultaneous determination of cadmium, lead, and mercury in seafood and plant-derived foods.
Heavy metal contamination in certain food remains a major public health concern due to the persistence, bioaccumulation, and toxicity of cadmium, lead, and mercury. In this study, we report the design and fabrication of a preconcentration-free electrochemical sensor based on magnesium-doped hydroxyapatite (Mg-HAP) nano...
