Particle Cell

Particle Cell is a Particle's cell, also This isnt really contained by everything, since this is Particle's cell, anyways Particle cell is a Collection from/of Particle. (basically smallest) 
There is chance of this might being a fictional thing, so i recommend mods to keep this. (probably)
Particle Cell can be Definitely found inside Particle, as this is cell of it (possibly) 
This probably might not exist.
