Antioxidant polymer particles. Enzymatic immobilization of catechin on polymer particles
Catechin-immobilizing polymer particles have been developed by laccase-catalyzed oxidation of catechin in the presence of amine-containing porous polymer particles. The resulting particles showed good scavenging activity toward stable free DPPH radical and ABTS radical cation.
