Clean break : Magnetic nanoparticles are fabricated with mesoporous anatase shells, which are biocompatible for enzyme immobilization (see picture; HRP=horseradish peroxidase). The nanobiocatalyst can be easily collected with an external magnet and recycled. Immobilized enzymes with low activity after several cycles can be decomposed with UV radiation and thus the nanoparticles are recyclable for new enzyme immobilization.
