Stealth Properties to Improve Therapeutic Efficacy of Drug Nanocarriers

Figure 4

Structures of PEG-lipid conjugates used in preparing stealth liposomes. The derivative is obtained with a PEG chain of 45 monomers, corresponding to a molecular weight of approximately 2000 Da. PEG units are capped at the distal end with a methoxy group, and conjugated to a DSPE lipid.
