- Abstract
- This study introduces a facile method to hybridize metal nanoparticles with lipid vesicles, which allows us to control over their membrane micro-fluidity. We have fabricated these hybrid liposomes by directly hybridizing metal nanoparticles with lipid bilayers solely consisting of 1,2-dipaimitoyl-snglycero-3-phosphatidylcholine (DPPC). For this, we have used the dehydration and rehydration method. Characterizing their morphology and micro-fluidity, in which we have used electron microscopy and fluorescence anisotropy spectroscopy, enables us to demonstrate that metal nanoparticles with different surface properties create interactions with either phosphorus end groups or hydrophobic tails of DPPC, thereby resulting in decrease in micro-fluidity of the assembled lipid membranes, especially for the hydrophobic layers. Our approach to hybridize metal nanoparticles in between lipid layers offers a flexible means that allows us to obtain a liposome system with more controllable membrane properties.
