Web8 apr. 2024 · CDs obtained at 300 °C (named Cu-CDs-300) have the most carboxyl content and Cu is coordinated in the form of CuN 2 O 2, which can better decompose H 2 O 2 to produce free radical and is beneficial to catalyze the oxidation of 3,3′,5,5′-tetramethylbenzidine (TMB). Alone, the HRP enzyme, or conjugates thereof, is of little value; its presence must be made visible using a substrate that, when oxidized by HRP using hydrogen peroxide as the oxidizing agent, yields a characteristic color change that is detectable by spectrophotometric methods. Numerous substrates for horseradish peroxidase have been described and co…
