    Conductance measurements in Laponite-stabilized internally self-assembled particles in water.

    We showed the possibility of creating a dense cover around lipid-based liquid crystalline drop-lets using laponite nanoplatelets as stabilizer. This is an interesting route for the design of new Colloid-ISAsome assemblies in which dense protective armours could be advantageous such as controlled delivery. The investigation of the structural by means of CRYO-TEM microscopy, DLS, and SANS with contrast variation conditions have been determined. Herein, we use conductivity measurements as trigger to deduce the ratio between the free and the adsorbed laponite-stabilizer. Phytantriol (PT) is used as the lipid to create the nanostructured drops. The conductivity measurements have been performed in AC conditions (ranging from 60 Hz to 600 KHz) in order to check out the electrical response of the soft materials. The results help in understand-ing the concentration of free stabilizer which is requisite for further applications since this could have an important influence on the properties of such complex and interesting smart assemblies.

    Conductance measurements in Laponite-stabilized inner nanostructured emulsions in water.

    We show the possibility of creating a dense cover around lipid-based liquid crystalline droplets using laponite nanoplatelets as stabilizer. This is an interesting route for the design of new Colloid-ISAsome assemblies in which dense protective armours could be advantageous such as controlled delivery. The investigation of the structural by means of CRYO-TEM microscopy, DLS, and SANS with contrast variation conditions have been determined.

    Herein, we use conductivity measurements as trigger to deduce the ratio between the free Na+ and the adsorbed laponite on the droplets. We used Phytantriol (PT, 3,7,11,15-tetramethylhexadecane-1,2,3-triol) as the lipid to create the nanostructured drops, laponite (radius of 14nm, thickness 1 nm). The conductivity measurements have been performed in AC conditions (ranging from 60 Hz to 600 KHz) in order to check out the electrical response of the soft materials. The results help in understanding the conditions in forming such complex and interesting smart assemblies.

    The European Colloid and Interface Society

    We recently show the possibility of creating a dense cover around lipid-based liquid crystalline droplets by partially hydrophobizing spherical colloids by introducing a cationic surfactant during the processing. This is an interesting route for the design of new Colloid-ISAsome assemblies in which dense protective armours could be advantageous such as controlled delivery. The investigation of the structural features as a function of the concentration of the cationic surfactant by means of CRYO-TEM microscopy, DLS, and SANS with contrast variation conditions indicates changes in the colloidal coverage.
    Herein, we use conductivity measurements as trigger to rationalize the link between the anionic spherical colloids and the cationic added surfactant. We used Phytantriol (PT, 3,7,11,15-tetramethylhexadecane-1,2,3-triol) as the lipid to create the nanostructured drops, silica sphere with a radius of 14 nm as the colloids and Cetyltrimethylammonium bromide (CTAB) as the linear positively charged detergent. The conductivity measurements have been performed both in DC and AC conditions in order to check out the electrical response of the soft materials. The results help in understanding the conditions in forming such complex and interesting smart assemblies.
