a portion of the nanoparticles in one embodiment it is generally desirable for the first liquid to dissolve at least about 10 wt of the nanoparticles in another embodiment it is generally desirable for the first liquid to dissolve at least about 20 wt of the nanoparticles in another embodiment it is generally desirable for the first liquid to dissolve at least about 50 wt of the nanoparticles in another embodiment it is generally desirable for the first liquid to dissolve at least about 80 wt of the nanoparticles in yet another embodiment it is generally desirable for the first liquid to dissolve at least about 100 wt of the nanoparticles the second liquid in addition to having a different dielectric constant from the first liquid does not solvate the nanoparticles in other words it is desirable for the second liquid not to cause the nanoparticles to swell or dissolve in it it is also desirable for the first liquid and the second liquid to be at least partially miscible in one another in one embodiment it is generally desirable for at least 10 wt of the first liquid to be miscible in the second liquid in another embodiment it is generally desirable for at least 20 wt of the first liquid to be miscible in the second liquid in yet another embodiment it is generally desirable for at least 50 wt of the first liquid to be miscible in the second liquid in yet another embodiment it is generally desirable for at least 75 wt of the first liquid to be miscible in the second liquid in yet another embodiment it is generally desirable for at least 100 wt of the first.
