Changes in the absorption band of asymmetric oscillations of CH2 groups of (A) non-PEGylated and (B) PEGylated magnetic liposomes after exposures to AC MF. Liposome composition: (A) eggPC/Chol (85:15 mol/mol) containing 1% wt. eggPC-coated MNP (5 nm); or (B) eggPC/DSPE-PEG2000/Chol (81:4:15 mol/mol) containing 1.8% wt. eggPC-coated 5 nm MNP. Liposome concentration 12 mg lipid/ml in 10 mM PBS, pH=7.4. Exposure to AC MF was carried out at r.t.. Error bars correspond to the precision of the peak position measurement (±0.2 cm−1).
