abstract = {In recent years, there has been a growing interest in the
formation of copolymers-lipids hybrid self-assemblies, which
allow combining and improving the main features of pure
lipids-based and copolymer-based systems known for their
potential applications in the biomedical field. In this
contribution we investigate the self-assembly behavior of
dipalmitoylphosphatidylcholine (DPPC) mixed with
poly(butadiene-b-ethyleneoxide) (PBD-PEO), both at the
micro- and at the nano-length scale.Epifluorescence
microscopy and Laser Scanning Confocal microscopy are
employed to characterize the morphology of micron-sized
hybrid vesicles. The presence of fluid-like inhomogeneities
in their membrane has been evidenced in all the investigated
range of compositions. Furthermore, a microfluidic set-up
characterizes the mechanical properties of the prepared
assemblies by measuring their deformation upon flow: hybrids
with low lipid content behave like pure polymer vesicles,
whereas objects mainly composed of lipids show more
variability from one vesicle to the other. Finally, the
structure of the nanosized assemblies is characterized
through a combination of Dynamic Light Scattering, Small
Angle Neutron Scattering and Transmission Electron
Microscopy. A vesicles-to-wormlike transition has been
evidenced due to the intimate mixing of DPPC and PBD-PEO at
the nanoscale. Combining experimental results at the micron
and at the nanoscale improves the fundamental understanding
on the phase behavior of copolymer-lipid hybrid assemblies,
which is a necessary prerequisite to tailor efficient
copolymer-lipid hybrid devices.},
