In order to thoroughly investigate the maximum amount of DSPE-PEG2000 that can be used to stabilize stealth liposomes, these were synthesized at different concentrations of DSPE-PEG2000 and their physicochemical properties were investigated by using differential scanning calorimetry (DSC).  The kinetics of PEGylation and de-PEGylation were performed by incubating non-stealth liposomes in a DSPE-PEG2000 suspension at different incubation times, and then analyzing the data using DSC and dynamic light scattering (DLS) techniques.
