Chemical and morphological effects of the contraceptive hormone 17 α-ethynylestradiol on fluid lipid membranes
(2021-08-01)
The lack of studies involving the effects in human health associated with the chronic ingestion of pollutants lead to the path of investigating the action of these compounds in cell membrane models. We demonstrated the ...
A model based in the radius of vesicles to predict the number of unilamellar liposomes
(A. Lakshmana Rao, 2014-06)
In particulate systems such as liposomes, concentration units are not enough to describe the drug distribution, as suspensions are not homogeneous. In certain in vitro assays, exposure to different number of particles ...
Giant phospholipid vesicles: Comparison among the whole lipid sample characteristics using different preparation methods - A two photon fluorescence microscopy study
(Elsevier Ireland, 2000-04)
Several methods for the preparation of giant unilamellar vesicles (GUVs) using synthetic phosphatidylcholine phospholipids were evaluated. We compared the physical characteristics - in terms of lamellarity and morphology ...
Lipid domains in giant unilamellar vesicles and their correspondence with equilibrium thermodynamic phases: A quantitative fluorescence microscopy imaging approach
(2009)
We report a novel analytical procedure to measure the surface areas of coexisting lipid domains in giant unilamellar vesicles (GUVs) based on image processing of 3D fluorescence microscopy data. The procedure involves the ...
Unilamellar vesicles obtained by simply mixing dioctadecyldimethylammonium chloride and bromide with water
(Elsevier B.V., 2006-04-01)
Optically clear dispersions of dioctadecyldimethylammonium bromide and chloride (DODAX, X = Br-, Cl-) in water can be obtained by simply mixing the amphiphiles at low concentrations (I mM) and at a temperature safely above ...

Characterization of a label system formed by large unilamellar vesicles for its potential use in the design of electrochemical biosensors
(Elsevier Science, 2018-07)
In this contribution a new electrochemical label system formed by DOPC/palmitic acid/cholesterol/sucrose large unilamellar vesicles (LUVs) with K4(Fe(CN)6) encapsulated is described and, characterized by using electrochemical ...
