Molecular ordering effects in bulk and at lipid/water nanoscopic interfaces: A story of water, light, and order

Water is ubiquitous on Earth, playing a critical role for a plethora of structures, processes and chemical reactions in nature. Its unique physicochemical properties originate mainly from its hydrogen bond network. Despite its recognized importance, many a ...

Shear Stress-Responsive Polymersome Nanoreactors Inspired by the Marine Bioluminescence of Dinoflagellates

Esther Amstad, Antoine Claude Jean Vian

Some marine plankton called dinoflagellates emit light in response to the movement of surrounding water, resulting in a phenomenon called milky seas or sea sparkle. The underlying concept, a shear-stress induced permeabilisation of biocatalytic reaction co ...

Soft matter probed by nonlinear scattering: self-assembly, interfaces, hydration, and long-range order

Jan Dedic

All organisms are made to a large extent of soft matter - macromolecules such as proteins and polysaccharides, or assemblies of small molecules such as lipids embedded in an aqueous environment. Understanding the role of order in soft matter presents a cha ...

Calcium-triggered fusion of lipid membranes is enabled by amphiphilic nanoparticles

Francesco Stellacci, Ye Yang, Ahmet Bekdemir, Zekiye Pelin Güven

Lipid membrane fusion is an essential process for a number of critical biological functions. The overall process is thermodynamically favorable but faces multiple kinetic barriers along the way. Inspired by nature's engineered proteins such as SNAP recepto ...

Dynamic Imaging of Lipid Membranes by Means of Water

Orly Bagunu Tarun

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 ...

Nanoparticle Liposome Interactions

Zekiye Pelin Güven

Protein-mimetic materials are of great interest for biotechnology to grant protein-like properties to artificial systems. Additionally, these materials can be used to shed light on the fundamental properties of proteins in many environments. Nanoparticles, ...

Curvature-Controlled Defect Localization in Elastic Surface Crystals

Pedro Miguel Nunes Pereira de Almeida Reis

We investigate the influence of curvature and topology on crystalline dimpled patterns on the surface of generic elastic bilayers. Our numerical analysis predicts that the total number of defects created by adiabatic compression exhibits universal quadrati ...

Functional surface engineering by nucleotide-modulated potassium channel insertion into polymer membranes attached to solid supports

Henning Paul-Julius Stahlberg

Planar solid-supported membranes based on amphiphilic block copolymers represent promising systems for the artificial creation of structural surfaces. Here we introduce a method for engineering functional planar solid-supported membranes through insertion ...

Electromagnetic characterisation of flexible conductive membranes at millimetre-waves

Herbert Shea, Julien Perruisseau-Carrier, Samuel Rosset, Luc Maffli, Pietro Romano

Presented is the experimental surface impedance characterisation of stretchable conductors at Ka-band, using a non-contact technique based on two-port rectangular waveguide measurements. Two different types of metallisations are analysed, namely gold ion i ...

Wagging the Tail: Essential Role of Substrate Flexibility in FAAH Catalysis

Ursula Röthlisberger, Andrea Cavalli, Pablo Campomanes Ramos, Giulia Palermo, Marilisa Neri

The serine hydrolase, fatty acid amide hydrolase (FAAH), is responsible for the intracellular degradation of anandamide and other bioactive fatty acid ethanolamides involved in the regulation of pain, inflammation, and other pathophysiological processes. T ...
