Impurity-induced peroxidase mimicry of nanoclay and its potential for the spectrophotometric determination of cholesterol.

A green version of the "Fe" impurity-induced peroxidase mimicry exhibited by simple and cheap substrate "nanoclay (NC)" along with the highly sensitive amperometric and spectrophotometric determination of cholesterol is demonstrated. The "Fe" impurity can act as the catalyst center for hydrogen peroxide reduction similar to the horseradish peroxidase (HRP… CONTINUE READING
