Facile synthesis of superparamagnetic mesoporous zeolite microspheres for the capacious enrichment of enzymes and proteins.
Superparamagnetic mesoporous zeolite microspheres with a large mesopore size of 13 nm and a high surface area of 382 m(2) g(-1) were synthesized for the capacious enrichment of proteins and enzymes. A high degree of ovalbumin immobilization was obtained (491 mg g(-1)) at pH 6, which is nearly twice that previously reported in the literature.
