1. Rheology and transition shapes of elastic liposomes in nanopores membranes / Reologia e transição de formas de lipossomas elasticos em membranas de nanoporos
In this work, liposomes prepared with comercial egg lecithin and octaoxyethylenelaurate-ester (PEG-8L) were characterized and studied in respect to PEG-8L incorporation, shape transitions, elasticity and rheology in nanopores membranes. Conventional liposomes (without PEG-8L) were used as control. The concentrated caffeine, extracted of guarana seeds, was in

2. Preparação e caracterização de lipossomas elasticos e elastico-magneticos para administração transdermica de moleculas bioativas / Preparation and characterization of elastic and elastic-magnetic liposomes for transdermal transport of drugs
The purpose of this work was to study the preparation and characterization of elastic and elastic-magnetic liposomes designed to facilitate the transdermal transport of drugs. The prepared liposomes were unilamellar, composed by synthetic dymirystoylphosphatidylcholine (DMPC), hydrogenated soy phosphatidylcholine or egg phosphatidylcholine (PCegg) as structu

3. Preparation of giant liposomes in physiological conditions and their characterization under an optical microscope.
Unilamellar liposomes with diameters of 25-100 microns were prepared in various physiological salt solutions, e.g., 100 mM KCl plus 1 mM CaCl2. Successful preparation of the giant liposomes at high ionic strengths required the inclusion of 10-20% of a charged lipid, such as phosphatidylglycerol, phosphatidylserine, phosphatidic acid, or cardiolipin, in phosp
