Polaric particle

From Memory Alpha, the free Star Trek reference

A polaric particle is a type of unusual subatomic particle.

Doctor Elias Giger's "cellular regeneration and entertainment chamber" generated highly charged polaric particles during operation. In 2373, these particles attracted the attention of Weyoun, whose guest quarters on Deep Space 9 were above Giger's. (DS9: "In the Cards")

Possibly related to or identical to polaric ions.
