Membrane interaction between Span 80 vesicle and phospholipid vesicle (liposome): Span 80 vesicle can perturb and hemifuse with liposomal membrane

Colloids and Surfaces B: Biointerfaces, 2013
We have focused on the interaction between the Span 80 vesicle and phospholipid vesicle (liposome). The Span 80 vesicle was mixed with a phospholipid vesicle (liposome), used as a simplified model of plasma membrane. From calcein leakage experiments, it was revealed that the interaction between the Span 80 vesicles and the liposomes could perturb the ...

Varying the Surface Charges of Gold Nanoparticles in Span 80, AOT, and Span 80 + AOT Micellar Systems in n-Decane

Russian Journal of Physical Chemistry A, 2020
Gold nanoparticles with different diameters of the metal core are obtained by reducing HAuCl4 with hydrazine in reverse emulsions stabilized by Span 80 (9.4 ± 0.4 nm), AOT (6.1 ± 0.2 nm), and an equimolar Span 80 + AOT mixture (10.0 ± 0.2 nm).

The aggregation of Span 80 in toluene

Journal of Solution Chemistry, 1993
The aggregation equilibria of the non-ionic surfactant Span 80 in toluene has been studied by vapour pressure osmometry (VPO) at different temperatures. The experimental data, treated both graphically and numerically using the LETAGROP-SUMPA program, can be explained by assuming the formation of dimers.

Structural Properties of Span 80/Tween 80 Reverse Micelles by Molecular Dynamics Simulations

The Journal of Physical Chemistry B, 2018
The sorbitan monooleate (Span 80)/poly(oxyethylene) sorbitan monooleate (Tween 80) reverse micelles (RMs) in the water-in- n-decane microemulsion were studied using the molecular dynamics simulation. The coexistence of the large RMs with the hydrodynamic radii Rh ∼ 10-20 nm and small RMs with Rh ∼ 1-2 nm was previously specified for this system. Models

Structures similar to lipid emulsions and liposomes. Dipalmitoylphosphatidylcholine, cholesterol, Tween 20–Span 20 or Tween 80–Span 80 in aqueous media

Journal of Liposome Research, 2016
In the present work, we show that we obtained nanometric structures made of water, 1,2-dipalmitoyl-sn-glycero-3-phosphatidylcholine (DPPC), cholesterol (Chol), and a mixture of ethoxylated and non-ethoxylated sorbitan fatty acid esters (Tween 20, Span 20, Tween 80, and Span 80) by mixing all of them near the cloud point temperature (cp) of the ...

Characterization of the addition of lipophilic Span 80 to the hydrophilic Tween 80-stabilized emulsions

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2014
Abstract Tween 80 was used as surfactant to create Tween 80-stabilized emulsions, and the consequences of the addition of Span 80 to the emulsions were examined. The conductivities and bottle tests of the emulsion system were monitored in the process to detect the phase inversions.

Investigation of PEG 6000/Tween 80/Span 80/H2O niosome microstructure

Colloid and Polymer Science, 2007
A stable niosome is prepared from Poly(ethylene glycol) [PEG] 6000/Tween 80/Span 80/H2O lamellar liquid crystal. The niosome structures and properties are studied by the methods of negative-staining transmission electron microscopy and small angle X-ray diffraction.
