The fluorescent control liposomes contain the lipophilic dye Dil incorporated in the bilayers. It has comparable physical and chemical attributes as for the Clophosome^®  except no active is encapsulated inside. It is used for tracking the cellular uptake of the liposomes by common methods like confocal, FACS, etc.

‘DiI’; DiIC18(3) is a lipophilic membrane dye. It is weakly fluorescent until incorporated into liposome membranes. This orange—red-fluorescent dye, which is spectrally similar to tetramethylrhodamine, is often used as a long-term tracer for neuronal and other cells.
