In this article, we present experimental observations backed by theoretical considerations which show that greater structures can be incorporated within vesicle membranes by promoting the clustering of nanoparticles before liposome formation. Cryo-transmission electron microscopy and cryo-electron tomography confirm these observations at unprecedented detail and underpin that the liposome membranes can accommodate flexible structures of up to 60 nm in size. These results imply that this material is more versatile in terms of inclusion capabilities and consequently widens the opportunities in developing multivalent vesicles for nanobiotechnology applications. application/pdf https://folia.unifr.ch/global/documents/303470 https://folia.unifr.ch/documents/303470/files/fin_inc.pdf https://folia.unifr.ch/documents/303470/files/fin_inc_sm.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.1021/nn406349z info:eu-repo/semantics/openAccess License undefined ACS Nano. - 2014, vol. 8, no. 4, p. 3451–3460 Liposomes Vesicles SPIONs Cryo TEM Cryo electron tomography Self assembly Membrane energetics Drug delivery info:eu-repo/classification/udc/53 Insertion of Nanoparticle Clusters into Vesicle Bilayers http://purl.org/coar/resource_type/c_6501
