Photothermal Properties of IR-780-Based Nanoparticles Depend on Nanocarrier Design: A Comparative Study on Synthetic Liposomes and Cell Membrane and Hybrid Biomimetic Vesicles

Pharmaceutics, 2023
Biomimetic nanoparticles hold great promise for photonic-mediated nanomedicine due to the association of the biological functionality of the membrane with the physical/chemical goals of organic/inorganic structures, but studies involving fluorescent ...

Electrostatically gated membrane permeability in inorganic protocells [PDF]

, 2013
Although several strategies are now available to produce functional microcompartments analogous to primitive cell-like structures, little progress has been made in generating protocell constructs with self-controlled membrane permeability.

Mover is a homomeric phospho-protein present on synaptic vesicles.

PLoS ONE, 2013
With remarkably few exceptions, the molecules mediating synaptic vesicle exocytosis at active zones are structurally and functionally conserved between vertebrates and invertebrates. Mover was found in a yeast-2-hybrid assay using the vertebrate-specific

Flippase‐Mediated Hybrid Vesicle Division

Advanced Materials
AbstractThe assembly of synthetic systems with the ability for protein‐mediated division remains a challenge in bottom‐up synthetic biology. Here, the reconstitution of an active Drs2p–Cdc50p lipid flippase in polymer lipid hybrid vesicles (HVs) made from phospholipids and 1 or 2.5 mol% amphiphilic block copolymers, with poly(carboxyethyl acrylate) or ...

Density Functional Simulation of Spontaneous Formation of Vesicle in Block Copolymer Solutions [PDF]

, 2007
We carry out numerical simulations of vesicle formation based on the density functional theory for block copolymer solutions. It is shown by solving the time evolution equations for concentrations that a polymer vesicle is spontaneously formed from the ...

Active Membrane Fluctuations Studied by Micropipet Aspiration [PDF]

, 2001
We present a detailed analysis of the micropipet experiments recently reported in J-B. Manneville et al., Phys. Rev. Lett. 82, 4356--4359 (1999), including a derivation of the expected behaviour of the membrane tension as a function of the areal strain ...

Freezing-induced self-assembly of amphiphilic molecules [PDF]

, 2017
The self-assembly of amphiphilic molecules usually takes place in a liquid phase, near room temperature. Here, using small angle X-ray scattering (SAXS) experiments performed in real time, we show that freezing of aqueous solutions of copolymer ...

Viscous regularization and r-adaptive remeshing for finite element analysis of lipid membrane mechanics

, 2007
As two-dimensional fluid shells, lipid bilayer membranes resist bending and stretching but are unable to sustain shear stresses. This property gives membranes the ability to adopt dramatic shape changes. In this paper, a finite element model is developed
