Passive and active ion permeation through lipid bilayers investigated by second harmonic water imaging

Lipid membranes are complex and dynamic systems which are known to mediate signaling processes between cells and their environment. To do this multiple ion channels and pumps are involved in controlling the in- and out-flux of various ions (K+, Na+, Mg2+, ...

Electronic and structural dynamics in DNA single strands

Benjamin Bauer

The absorption, conversion and transport of electronic energy in molecular aggregates is at the heart of many important natural and artificial photochemical systems, including organic solar cell materials, photosynthetic light-harvesting complexes and DNA ...

Doping challenges and pathways to industrial scalability of III–V nanowire arrays

Anna Fontcuberta i Morral, Lucas Güniat, Wonjong Kim, Valerio Piazza

Semiconductor nanowires (NWs) have been investigated for decades, but their application into commercial products is still difficult to achieve, with triggering causes related to the fabrication cost and structure complexity. Dopant control at the nanoscale ...

Aggregation of discoidal particles due to depletion interaction

Ignacio Pagonabarraga Mora

Depletion interactions between colloids of discoidal shape can induce their self-assembly into columnar aggregates. This is an effect of entropic origin with important implications in a range of colloidal systems, particularly in the clustering of erythroc ...

Coordination-Driven Monolayer-to-Bilayer Transition in Two-Dimensional Metal–Organic Networks

Henning Paul-Julius Stahlberg, Patrick Shahgaldian, Mina Moradi

We report on monolayer-to-bilayer transitions in 2D metal–organic networks (MONs) from amphiphiles supported at the water–air interface. Functionalized calix[4]arenes are assembled through the coordination of selected transition metal ions to yield monomol ...

Development of soft microscopic implants and acoustically-powered machines for biomedical applications

Murat Kaynak

The development of miniaturized machines that can actively cross barriers, navigate through heterogeneous materials and access remote sites can revolutionize environmental inspection and targeted therapy. Seminal work demonstrated the feasibility of follow ...

Tuning SAS-6 architecture with monobodies impairs distinct steps of centriole assembly

Tatiana Favez, Pierre Gönczy, Virginie Hamel, Santiago Harald Andany, Georg Fantner, Oliver Hantschel, Georgios Hatzopoulos, Niccolo Banterle

Centrioles are evolutionarily conserved multi-protein organelles essential for forming cilia and centrosomes. Centriole biogenesis begins with self-assembly of SAS-6 proteins into 9-fold symmetrical ring polymers, which then stack into a cartwheel that sca ...

Membrane Activity of a DNA-Based Ion Channel Depends on the Stability of Its Double-Stranded Structure

Himanshu Joshi, Diana Kornelia Morzy

DNA nanotechnology has emerged as a promising method for designing spontaneously inserting and fully controllable synthetic ion channels. However, both insertion efficiency and stability of existing DNA-based membrane channels leave much room for improveme ...

Mechanical principles of engineering fibrous tissues with programmable shape

Erik Mailand

The form and structure of biological tissues define their function. The emergence of tissue morphology during development is one of the wonders of nature. Cells mechanically probe and manipulate their surroundings while constructing structures from the ext ...

Post-translational regulation of neuronal differentiation

Jaipreet Singh Loomba

Glycosphingolipids (GSLs) are amphipathic lipid moieties that make up only 3% of the total lipid content of the cell and are almost exclusively expressed at the Plasma Membrane(PM). They are key drivers of signalling hotspots known as â lipid-raftsâ as ...

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 ...

Hexayne Amphiphiles and Bolaamphiphiles

Rosario Scopelliti, Holger Frauenrath, Enzo Jean Raymond Bomal, Vincent Matthieu Guillaume Croué, Reuben Yeo Jueyuan

Oligoynes with two or more conjugated carbon-carbon triple bonds are useful precursors for carbon-rich nanomaterials. However, their range of app0lications has so far been severly limited by the challenging syntheses, particularly in the case of oligoynes ...
