Discriminative Detection of Dopamine and Tyrosinase Based on Polydopamine Dots Triggered by Fenton-like Activity of Mn3O4 Nanoparticles

In this work, the inherent Fenton-like activity of Mn3O4 nanoparticles (Mn3O4 NPs) was explored to catalyze the polymerization of dopamine to blue-emitting polydopamine dots (PDA-dots), which can b...
