n.
A small, sometimes microscopic capsule designed to release its contents when broken by pressure, dissolved, or melted.

Immunology
Magnetic microcapsule, see there.
 
Microbiology
An antigenic virtual layer surrounding some bacteria.
 
Therapeutics
A biohybrid device in which cells of interest (e.g., pancreatic islet cells) are encapsulated in alginate poly-l-lysine or for xenografts, simple alginate, to be delivered to a target tissue.

Microcapsules circumvent host immunity and are promising of the biohybrid “organs”, as they are easily implanted (requiring simple injection by a “standard issue” syringe), biocompatible, and achieve excellent glucose control.
