Interactions Between Natural Herbicides and Lipid Bilayers Mimicking the Plant Plasma Membrane
Frontiers in Plant Science, 2019 Natural phytotoxic compounds could become an alternative to traditional herbicides in the framework of sustainable agriculture. Nonanoic acid, sarmentine and sorgoleone are such molecules extracted from plants and able to inhibit the growth of various ...

Geodesic curvature driven surface microdomain formation [PDF]
, 2016 Lipid bilayer membranes are not uniform and clusters of lipids in a more ordered state exist within the generally disorder lipid milieu of the membrane. These clusters of ordered lipids microdomains are now referred to as lipid rafts. Recent reports attribute the formation of these microdomains to the geometrical and molecular mechanical mismatch of ...

Self-assembled DNA nanopores that span lipid bilayers.
Nano letters (Print), 2013 DNA nanotechnology excels at rationally designing bottom-up structures that can functionally replicate naturally occurring proteins. Here we describe the design and generation of a stable DNA-based nanopore that structurally mimics the amphiphilic nature

Advanced Healthcare Materials, EarlyView.Negative‐ and positive‐staining TEM is essential for rapid nanometer‐resolution characterization of organic specimens ranging from nanoparticles to cells. Uranyl salts are widely used negative‐/positive‐stains but are radioactive and highly toxic to users and the environment.

Exploring the Free Energy Landscape of Solutes Embedded in Lipid Bilayers.
Journal of Physical Chemistry Letters, 2013 Free energy calculations are vital for our understanding of biological processes on an atomistic scale and can offer insight to various mechanisms. However, in some cases, degrees of freedom (DOFs) orthogonal to the reaction coordinate have high energy ...

Advanced Healthcare Materials, EarlyView.Small extracellular vesicles (sEVs) are encapsulated into protective shells composed of metal‐phenolic networks (MPNs) and secondary poly(ethylene glycol) layers. This surface modification approach enhances the storage stability of sEVs while maintaining their integrity and functionality. The shells can be selectively disassembled under mild conditions.

Atomistic simulations of a multicomponent asymmetric lipid bilayer
, 2012 The cell membrane is inherently asymmetric and heterogeneous in its composition, a feature that is crucial for its function. Using atomistic molecular dynamics simulations, the physical properties of a 3-component asymmetric mixed lipid bilayer system ...

Coherent collective dynamics in phospholipid membranes: where are we now?
Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2020 We review the main achievements accomplished in the study of the coherent collective dynamics of phospholipid membranes, i.e., the collective vibrational excitations active on the sub-picoseconds to picoseconds time scale and terahertz frequencies, over ...
