Efficient biomimetic catalases have been broadly explored for free-radical scavenging and antioxidative stress. Herein, we introduce a non-toxic Se-modified carbon nitride (CN) nanosheet for this bioapplication, and it presents efficient catalase activity, high fluorescence properties, and good biocompatibility. These properties indicate that this material has potential for use as an artificial enzyme against oxidative stress.
