In vitro utilization of liposomes is now recognized as a powerful tool in many bioscience investigations and their associated clinical studies, e.g., liposomes in drug targeting; liposomes in gene transport across plasma and nuclear membranes; liposomes in enzyme therapy in patients with genetic disorders. However, before these areas can be effectively explored, many basic areas in liposome research require elucidation, including: (a) attachment of liposomes to cell surfaces; (b) permeation of liposomes through the plasma membranes; and (c) stability of liposomes in cell or nuclear matrices....
