The application of magnetic nanocarriers offers new perspectives for use
as enzyme immobilization. This study investigates the surface
modification of iron oxide magnetite with phenolic compounds. Some
structurally related influences of functionalizing molecules are
observed on the binding to the magnetite particles. Here caffeic acid
and 3,4-dihydroxyphenylalanine have shown to form the most stable
bindings. Additionally they are capable of stabilizing the particle
suspension on neutral pH level. In a subsequent enzyme immobilization
with lipase Candida rugosa a residual activity could be detected up to
75 % in case of caffeic acid functionalized particles.
