Layer by Layer Self-Assembled Polyelectrolyte Multilayers with Embedded Phospholipid Vesicles

Langmuir, 2004
We describe a method to embed phospholipid vesicles into polyelectrolyte multilayers built up by the alternate deposition of polyanions and polycations. Before deposition, the vesicles are rigidified by polycation adsorption onto their surface avoiding their fusion once deposited on the multilayer surface.

Conduction Properties of Layer-by-Layer Self-Assembled Multilayer Nanoparticulate Structures

Journal of Nanoelectronics and Optoelectronics, 2008
Nanoparticles based multilayer fabricated using layer-by-layer (LbL) self assembly process mediated through polyelectrolytes is reported as an interesting alternative for the fabrication of electronic devices. The effect of deposition cycle on the current-voltage characteristics of thin multilayer devices composed of alternating layers of chitosan ...

Wool keratin: A novel building block for layer-by-layer self-assembly

Journal of Colloid and Interface Science, 2009
We utilize the extracted water-soluble wool keratin as the building block for the layer-by-layer (LbL) assembly. By adjusting the solution pH, keratin can be used as polycation or polyanion. Experimental results indicate that multilayer films of keratin together with other synthetic polyelectrolytes have been fabricated successfully. We have found that

Dual Drug Delivery Microcapsules via Layer-by-Layer Self-Assembly

Langmuir, 2009
The integration of hydrophobic and hydrophilic drugs in the polymer microcapsule offers the possibility of developing a new drug delivery system that combines the best features of these two distinct classes of material. Recently, we have reported the encapsulation of an uncharged water-insoluble drug in the polymer membrane.

Layer-by-layer self-assembly: The contribution of hydrophobic interactions

Nanostructured Materials, 1999
Abstract The layer-by-layer (LBL) adsorption of polyelectrolytes and other compounds is considered to be the result of electrostatic attraction between ionic side-groups of a polymer backbone to oppositely charged groups located on the surface of a substrate. The energy of electrostatic attraction, transformation of ionic atmosphere and the hydration

Nanocapsules via Layer-by-Layer self-assembly technique

2011
Since the drug molecules inside human body (in the blood vessel) are recognised as being alien, and quickly eliminated or degraded, it is necessary to find a way to protect and direct these effective components to the target zone. Therefore, the design and preparation of the therapeutic delivery systems in vivo has attracted considerable attention in ...
