Magnetic zeolite microspheres are synthesized by combining sol‐gel synthesis and vapor‐phase transport. The microspheres, which have magnetite cores and crystalline zeolite shells (see figure), exhibit super‐paramagnetism and a high adsorption capacity for trypsin. Trypsin‐adsorbed microspheres digest proteins very efficiently (in only 15 s) in the presence of microwave radiation.
