Biocatalytic
activity of amyloglucosidase (AMG), immobilized on
superparamagnetic nanoparticles, is dynamically and reversibly activated
or inhibited by applying a magnetic field. The magnetic field triggers
aggregation/deaggregation of magnetic particles that are also functionalized
with urease or esterase enzymes. These enzymes produce a local pH
change in the vicinity of the particles changing the AMG activity.
