| It has been reported that doxorubicin can be concentrated to such an extent within liposomes that gelation takes place in the presence of the divalent sulfate counterion. |
|
| To preserve the electrical neutrality of the resin, each fixed ion must be neutralised with a counterion. |
|
| In fact, the affinity of anions toward cationic micellar aggregates, that is the degree of counterion binding, has been found to follow the Hofmeister series. |
|
| Use of a dye in a thermal dye transfer diffusion process comprising a cationic dye obtained by exchanging an inorganic counterion of a hydrophilic cationic dye by a hydrophobic organic ion. |
|
| This counterion is mobile and can get into and out of the resin bead. |
