Figure 2. Characterizing ICG binding to DOTAP liposomes:

Figure 2

A) ICG binding to liposomes containing variable amounts of DOTAP. B) ICG binding to DOTAP liposomes (45 mol. % DOTAP) with varying liposome concentration. C) Binding of ICG to DOTAP liposomes with or without 5 mol. % PEG-DSPE included. D) Kinetics of ICG binding to DOTAP liposomes at indicated temperatures. Calculated absorption values of ICG at 800 nm with or without DOTAP liposomes following incubation at varying pH (E) or elevated temperatures (F). Error bars reflect mean +/− std. dev. for n=3 samples.
