Influence of iron oxide nanoparticles on bending elasticity and bilayer fluidity of phosphotidylcholine liposomal membranes

- Liposomes loaded with bare and silica coated iron oxide particles were prepared.
- Silica coated particles have stronger effect on elasticity and membrane fluidity.
- Silica coating provide high negative surface potential to the nanoparticles.
- Silica coated nanoparticles destabilize the membrane leading to altered properties.
