Preparation of zeolite microspheres and their application in biology

Abstract

Hollow zeolite microspheres were prepared by growing a thin zeolite membrane shell on seeded polystyrene beads. The removal of the organic growth directing agent and polystyrene bead was successfully performed without damaging the thin zeolite shell. The storage and delivery of sodium pervanadate, a potent tyrophosphatase inhibitor to MDCK cells was successfully carried out. Thus, demonstrating the potential use of these materials for biological studies of cell signaling
