F. Frezard et al., FLUORINATED PHOSPHOLIPID-BASED VESICLES AS POTENTIAL-DRUG CARRIERS - ENCAPSULATION SUSTAINING OF DRUGS AND STABILITY IN HUMAN SERUM/, Artificial cells, blood substitutes, and immobilization biotechnology, 22(4), 1994, pp. 1403-1408
The release of entrapped 5(6)-carboxyfluorescein from fluorinated vesi
cles in a buffer or in human serum is considerably less than that from
hydrogenated liposomes. The presence of a fluorinated core inside the
liposomal membrane definitely reduces its permeability. In some cases
, the stability of liposomes made from fluorinated phospholipids alone
is better than that of egg phosphatidylcholine cholesterol 1/1 vesicl
es, which are among the least permeable and most stable hydrogenated l
iposomes.
