Insertion of Nanoparticle Clusters into Vesicle Bilayers

Rudolf Hovius, Davide Demurtas, Alke Fink

A major contemporary concern in developing eective liposomeÀnanoparticle hybrids is the present inclusion size limitation of nanoparticles between vesicle bilayers, which is considered to be around 6.5 nm in diameter. In this article, we present experimen ...

Enhancing Radiotherapy by Lipid Nanocapsule-Mediated Delivery of Amphiphilic Gold Nanoparticles to Intracellular Membranes

Francesco Stellacci, Randy Patrick Carney, Ye Yang

Amphiphilic gold nanoparticles (amph-NPs), composed of gold cores surrounded by an amphiphilic mixed organic ligand shell, are capable of embedding within and traversing lipid membranes. Here we describe a strategy using crosslink-stabilized lipid nanocaps ...

Bilayer splitting and wave functions symmetry in Sr3Ir2O7

Henrik Moodysson Rønnow, Marco Grioni, Johan Juul Chang, Luca Moreschini, Simon Karl Moser, Bastien Dalla Piazza

The influence of dimensionality on the electronic properties of layered perovskite materials remains an outstanding issue. We address it here for Sr3Ir2O7, the bilayer compound of the iridate Srn+1IrnO3n+1 series. By angle-resolved photoemission spectrosco ...

Ultrathin Shell Double Emulsion Templated Giant Unilamellar Lipid Vesicles with Controlled Microdomain Formation

Esther Amstad

A microfluidic approach is reported for the high-throughput, continuous production of giant unilamellar vesicles (GUVs) using water-in-oil-in-water double emulsion drops as templates. Importantly, these emulsion drops have ultrathin shells; this minimizes ...

Interplay of Packing and Flip-flop in Local Bilayer Deformation. How Phosphatidylglycerol Could Rescue Mitochondrial Function in a Cardiolipin-deficient Yeast Mutant

Anne-Florence Raphaëlle Bitbol, Mohammad Rahimi

In a previous work, we have shown that a spatially localized transmembrane pH gradient, produced by acid micro-injection near the external side of cardiolipin-containing giant unilamellar vesicles, leads to the formation of tubules that retract after the d ...

Spatial SPION Localization in Liposome Membranes

Davide Demurtas, Alke Fink

Nanocarriers, including liposomes, offer great opportunities for targeted and controlled therapy. The development in this field has led to a large panel of drug delivery systems, which can be classified into 3 different nanovector generations. However, the ...

Selective Delivery of an Anticancer Drug with Aptamer-functionalized Liposomes to Breast Cancer Cells in vitro and in vivo

Li Tang, Yi Lu

Selective targeting of cancer cells is a critical step in cancer diagnosis and therapy. To address this need, DNA aptamers have attracted significant attention as possible targeting ligands. However, while their use in targeting cancer cells in vitro has b ...

Hepatitis B subvirus particles display both a fluid bilayer membrane and a strong resistance to freeze drying: a study by solid-state NMR, light scattering, and cryo-electron microscopy/tomography

Paul Guichard

Hepatitis B surface antigen (HBsAg) subvirus particles produced from yeast share immunological determinants with mature viruses, which enable the use of HBsAg as a potent antigen for human vaccination. Because the intimate structure of such pseudoviral par ...

Effect of Particle Diameter and Surface Composition on the Spontaneous Fusion of Monolayer-Protected Gold Nanoparticles with Lipid Bilayers

Francesco Stellacci, Randy Patrick Carney, Ye Yang

Anionic, monolayer-protected gold nanoparticles (AuNPs) have been shown to nondisruptively penetrate cellular membranes. Here, we show that a critical first step in the penetration process is potentially the fusion of such AuNPs with lipid bilayers. Free e ...
