We investigate the microstructure of copolymer micellar solutions with embedded laponite colloidal particles. The solutions exhibit microscopic confinement of the coated nanoparticles triggered by increasing the temperature above the gelation tempera

Polylactide homopolymers, polylactide and poly(ethylene oxide) diblock and triblock copolymers are used to prepare spherical microparticles by using the single oil-in-water emulsion and solvent evaporation technique. We are able to create both bulk a

The phase behavior and microstructure of the ternary system water/1-butyl-3-methylimidazolium hexafluorophosphate (bmimPF(6))/Triton X-100 was studied as a function of temperature and ionic liquid (IL) mass fraction alpha. In the present study, a hyd

Equimolar mixtures of large unilamellar vesicles (LUVs) obtained from mixtures of egg lecithin and lipids containing complementary hydrogen bonding head groups (barbituric acid (BAR) and 2,4,6triaminopyrimidine (TAP)) were shown to aggregate and fuse

We have studied the pearling instability induced on hollow tubular lipid vesicles by hydrophilic polymers with hydrophobic side groups along the backbone. The results show that the polymer concentration is coupled to local membrane curvature. The rel

Evanescent wave induced fluorescence microscopy combined with phase contrast microscopy is applied to study the strong electrostatic adhesion of giant unilamellar vesicles (GUV) on flat surfaces. This technique gives the shape of the adsorbed vesicle

We present a new method to study the adsorption of vesicles on solid substrates, combining the use of the evanescent wave-induced fluorescence (EWIF) and classical optical microscopy. We show in this paper that our method can clearly discriminate bet

Giant unilamellar vesicles (GUV) from diacetylenic phospholipid, 1,2 bis (heptacosa-8,10-diynoyl)-sn-glycero-3-phosphocholine (DC6,15PC), have been prepared by applying electric field to the aqueous dispersion maintained above its chain melting trans

The concept of toposelectively modified vesicles (toposomes) is presented. The application of an electric field vector constitutes a method by which these objects can be created. The effect of mill...

Due to the increasing use of nanometric cerium oxide in applications, concerns about the toxicity of these particles have been raised and have resulted in a large number of studies. We report here on the interactions between 7 nm anionically charged
