eikapseloitu

Eikapseloitu is a Finnish adjective meaning not encapsulated. It is used in scientific contexts to describe objects that lack a surrounding capsule, coat, or protective envelope. The term is typically contrasted with kapseloitu (encapsulated).

In Finnish, negation of kapseloitu is usually written ei kapseloitu as two words, but some writers employ the compound form eikapseloitu in field-specific texts. The precise orthography can vary by style guide.

In microbiology, eikapseloitu describes bacterial strains that lack a polysaccharide capsule. The capsule can shield bacteria from immune responses; therefore non-encapsulated strains may differ in virulence and in recognition by vaccines and serotyping methods.

In medicine and nanotechnology, eikapseloitu formulations refer to active ingredients that are not enclosed in a carrier capsule or shell. Such formulations often have distinct solubility, release, and biodistribution properties compared with encapsulated forms.
