Under dehydration conditions, amphipathic late embryogenesis abundant proteins fold spontaneously from a random conformation into α-helical structures, and this transition is promoted by the presence of membranes. To gain insight into the thermodynamics of membrane association, we model the resulting α-helical structures […]

Increasing awareness of bioeffects and toxicity of nanomaterials interacting with cells puts in focus the mechanisms by which nanomaterials can cross lipid membranes. Apart from well-discussed energy-dependent endocytosis for large objects and passive diffusion through membranes by solute molecules, there can […]

Organisms are well known to produce their own antibiotic host-defence peptides that act through damaging bacterial membranes due to their different molecular composition compared to the host organism’s own cells. Some of these antimicrobial peptides are also known to have anticancer properties. One particularly promising anticancer peptide is polybia MP1 (MP1) from the venom of […]

The insufficient delivery of biomacromolecular therapeutic agents into the cytoplasm of mammalian cells remains a major barrier to their pharmaceutical applications. Cell-penetrating peptides (CPPs) are considered as potential carriers for cytoplasmic delivery of macromolecular drugs. However, due to the positive charge of most CPPs, strong non-specific cell […]

This study reports a series of novel amino acid based dual-responsive hydrogels. Prepared by a facile one-pot 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC) coupling reaction, the solid content, structure, and mechanical behavior of hydrogels could be easily adjusted by changing the concentrations of the polymers and the crosslinkers. With pH-responsive anionic pseudo-peptides […]
As the year 2015 was coming to its end, SNAL ESRs gathered again in Strasbourg to get their last dose of new and contemporary ideas in the field of Lipid Membrane Research.

Directional growth caused by gravitropism and corresponding bending of plant cells has been explored since 19th century, however, many aspects of mechanisms underlying the perception of gravity at the molecular level are still not well known. Perception of gravity in root and shoot gravitropisms is usually attributed to gravisensitive […]

Lipid membranes are the basic building blocks for almost all living organisms. For years numerous reports have been focused on this area to establish a comprehensive understanding of membrane structures. More recently, the development of modern experimental techniques, such as small-angle X-ray scattering, small-angle neutron scattering and […]

Some materials can see their macroscopic properties drastically influenced by the microscopic structure they exhibit. This is particularly the case when these materials are composed of geometrically constrained macromolecules. For example, in tire industry, the usage properties of silica filled elastomers are strongly dependent of the morphological details of the silica aggregates and of the […]

Recent experimental studies indicate that polymeric structures with a well-adjusted balance of amphiphilic parts may translocate through self-assembled phospholipid bilayers and enhance the passive trans-membrane transport of smaller molecules. Using a coarse grained lattice Monte Carlo model with explicit solvent we investigate self-assembled lipid […]

The stability of micelles self-assembled from block co-polymers can be altered by the degradation of the blocks. Slow degradation shifts the equilibrium size distribution of block co-polymer micelles and changes their properties. The quasi-equilibrium scaling theory shows that the degradation of hydrophobic blocks in the core of […]
Many surfaces found in nature possess sophisticated topographical structures which provide them with exceptional properties. Nano-structured surface of lotus leafs efficiently repel water, microscopic brushes of gecko fingers drastically increase the contact with surfaces, topographical structures provides for enhanced anti-reflection surface properties in insects. Self-cleaning ability of bio-surfaces enables them to prevent contamination by particles […]
Cell membranes represent a serious protective barrier for external molecules, proteins, nanoparticles and drugs. This barrier is quite efficient in protecting the interior of the cells. However, large nanoscale objects, single-walled carbon nanotubes (SWNTs) have been found inside the cells both in direct and indirect biological experiments. Such experiments suggest that carbon nanotubes can efficiently […]

Nanotube patterning may occur naturally upon the spontaneous self-assembly of biomolecules onto the surface of single-walled carbon nanotubes (SWNTs). It results in periodically alternating bands of surface properties, ranging from relatively hydrophilic to hydrophobic, along the axis of the nanotube. Single-chain mean field (SCMF) […]

Great efficiency to penetrate into living cells is attributed to carbon nanotubes due to a number of direct and indirect observations of carbon nanotubes inside the cells. However, a direct evidence of physical translocation of nanotubes through phospholipid bilayers and the exact microscopic mechanism of their […]
