Sub‐Micrometer Vaterite Containers: Synthesis, Substance Loading, and Release

Abstract

Simply smaller: Sub-micrometer vaterite particles (see picture) were synthesized by modifying the crystal growth parameters. Their porous structure allows the loading and storage of various payloads. The recystallization to calcite in aqueous solutions can be used as a release mechanism. The release can be controlled by the properties of the immersion medium, thereby creating a simple, cost-effective, and versatile system for drug-delivery applications.
