A domain is a with liquid filled room. Where liquid molecules with a same architectur are exposed to fields of charge carriers.
That happens in the body in the environment of charges carrying cell membrans, charges carrying poliglycanes and pathologically carges carrying stored molecules, they could not be excreted and disposed of. They are electrically isolated by watercluster.
Such an aerea creates a region, cut off from the normal exchange of substances.
Powerlight has here the target and breaks domain contributory clusters and makes a better solubility of stored substances by electron transfer
