abstract = {The interactions between nanoparticles and vesicles are of
significant interest both from a fundamental as well as from
a practical point of view, as vesicles can serve as a model
system for cell membranes. Accordingly the effect of
nanoparticles that bind to the vesicle bilayer is very
important with respect to understanding their biological
impact and also may shed some light on the mechanisms behind
the effect of nanotoxicity. In this study we have
investigated the influence of small adsorbed silica
nanoparticles (SiNPs) on the structure of zwitterionic DOPC
vesicles. By a combination of SANS, cryo-TEM, and DLS, we
observed that the SiNPs are bound to the outer vesicle
surface without significantly affecting the vesicle
structure. Most interestingly, by means of neutron spin-echo
(NSE) local bilayer fluctuations were studied and one finds
a small but marked decrease of the membrane rigidity upon
binding of the nanoparticles. This surprising finding may be
a relevant aspect for the further understanding of the
effects that nanoparticles have on phospholipid bilayers},
