Detection of copper ions in liquid foods and beverages based on an enzymatic method

Construction and Application of Nanozyme Sensor Arrays

“…Most of the natural enzymes are proteins produced by living cells. As high-quality biocatalysts with high efficiency, strong specificity, and mild reaction conditions, natural enzymes have been widely used in medicine, agriculture, the chemical industry, and food detection. − However, owing to the disadvantages of being expensive, having poor stability, and easily losing catalytic activity when environmental impacts are not suitable, such as extreme pH and high temperature, its actual production application has been limited . Moreover, enzymes could be degraded by proteases without difficulty.…”
