microcapsules
Miniature payload carriers
Microcapsules are tiny spherical containers, typically microscopic, with a coating that encloses an active substance.
The coating protects the contents and controls their release—dissolving on contact, breaking under pressure, or degrading over time.
Applications include time-release medications, scratch-and-sniff surfaces, and self-healing materials where microcapsules release adhesive when cracked.
