Copper–carbon dot aerogel: a high-performance mimetic peroxidase and its application for versatile colorimetric bioassays

exhibited a high peroxidase-like activity. Combining the observation with multienzyme cascade reactions, versatile colorimetric bioassays of hydrogen peroxide as well as diabetes-associated glucose and α-glucosidase were explored and then extended to screen α-glucosidase inhibitors that are used as antidiabetic and antiviral agents.
