Micro- or nanostructured optical element
Niels Quack, Dorian Giraud Herle
A micro- or nanostructured optical element (1) is proposed comprising: a membrane (3) with an array of holes (5), the membrane (3) comprising a membrane light wave facing surface; an array of pillars (7) sized and shaped such that a respective pillar (7) i ...
2023Effects of thermal, mechanical, and electrostatic perturbations on lipid membrane hydration investigated by second harmonic imaging
Hydrated lipid bilayer membranes are crucial components of cells and organelles, serving as the outer boundary that separates the cellular components from the extracellular environment. Lipid membranes regulate their structures and functions by dynamically ...
EPFL2023Homogenization theory captures macroscopic flow discontinuities across Janus membranes
François Gallaire, Pier Giuseppe Ledda, Giuseppe Antonio Zampogna, Kevin Wittkowski
Janus membranes, thin permeable structures with chemical and geometrical asymmetric properties, show great potential in industrial separation processes. Yet the link between the micro- and macro-scale behaviours of these membranes needs to be established r ...
CAMBRIDGE UNIV PRESS2023Cytotoxicity, Accumulation and Translocation of Silver and Silver Sulfide Nanoparticles in contact with Rainbow Trout Intestinal Cells
Silver nanoparticles (Ag NPs) are widely used in consumer products especially because of their antimicrobial properties. However, this wide usage of Ag NPs is accompanied by their release into the environment where they will be rapidly transformed to other ...

Implantable drug delivery systems that can realize a scheduled drug release according to the needs of patients would be highly beneficial for the treatment of chronic diseases and cancer. Here, micrometer‐sized hydrogel particles with both thermal and pH s ...
2020Comb Transducer for Generation of SH0 Mode in Crystalline Piezoelectric Membrane
Soumya Yandrapalli, Victor Plessky
It is shown that the comb IDT (CT) can efficiently excite SH0 mode in piezoelectric membrane of suitable orientation. The transducer has pitch equal to the wavelength (p=lambda) and the electrode size is half of the wavelength. As compared to conventional ...
IEEE2020Chemistry of Lipid Membranes from Models to Living Systems: A Perspective of Hydration, Surface Potential, Curvature, Confinement and Heterogeneity
Sylvie Roke, Orly Bagunu Tarun, Halil Ibrahim Okur
Lipid membranes provide diverse and essential functions in our cells relating to transport, energy harvesting and signaling. This variety of functions is controlled by the molecular architecture, such as the presence of hydrating water, specific chemical c ...
2019Dynamic Imaging of Lipid Membranes by Means of Water
Lipid membranes are self-assembled structures whose composition determines the properties of membranes of cells and organelles. The molecular level understanding of lipid membranes is based on spectroscopy and MD simulations of lipid monolayer systems. As ...
EPFL2019Characterization of Coenzyme Q Biosynthesis Proteins through Integrative Modeling at the Protein-Membrane Interface
Integral and peripheral membrane proteins account for one-third of the human proteome, and they are estimated to represent the target for over 50% of modern medicinal drugs. Despite their central role in medicine, the complex, heterogeneous and dynamic nat ...
EPFL2019Label-free detection of hypoxia-induced extracellular vesicle secretion from MCF-7 cells
Philippe Renaud, Sandro Carrara, Tugba Kilic, Ana Teresa De Sousa Valinhas
Nanoscale extracellular vesicles (EVs) including exosomes (50–150 nm membrane particles) have emerged as promising cancer biomarkers due to the carried genetic information about the parental cells. However the sensitive detection of these vesicles remains ...
