Nanoconfined Polyelectrolyte Multilayers
Advanced Materials, 2006 Lateral nanometer-scale control over the growth of polyelectrolyte (layer-by-layer) multilayers is demonstrated down to 40 nm, which is well below the natural size of the macromolecules in solution. Because of confinement upon adsorption, the molecules change conformation as compared with the usual, macroscopic case (see Figure). This work opens direct

Formation of Polyelectrolyte Multilayers
Langmuir, 2000 A mechanism for the formation of polyelectrolyte multilayers is proposed. All of the experiments on such systems show that there is strong interpenetration of consecutive layers. We explain the very strong stability of the multilayers by the complexation between polyelectrolytes of opposite signs.

Water and Ion Pairing in Polyelectrolyte Multilayers
Langmuir, 1999 The water content in multilayers made from poly(styrenesulfonate) and poly(diallyldimethylammonium chloride) was determined using infrared spectroscopy and thermal gravimetric analysis. Under ambient conditions the polyelectrolyte multilayer contains 10−20 wt % water, which is removed by heating under dry conditions to 100 °C.

Responsive polyelectrolyte multilayers
Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2007 In this review we present selected recent developments of responsive multilayers formed by layer-by-layer assembly of oppositely charged polymers, with particular emphasis on the preparation of temperature- and pH-sensitive systems. We discuss the influence of the architecture and of the nature of the polyelectrolytes used on the responsive behavior of

Lateral Mobility of Polyelectrolyte Chains in Multilayers
The Journal of Physical Chemistry B, 2007 In this work, the lateral mobility of polyelectrolyte multilayers was investigated by means of the fluorescence recovery after photobleaching (FRAP) technique, with special attention to the effect of relevant parameters during and after preparation. Different polyelectrolytes with respect to charge density, stiffness, and hydrophilicity were compared ...

Encapsulation of Opiorphin in Polymer-coated Alginate Beads for Controlled Delivery and Painkilling [PDF]
International Journal Bioautomation, 2021 Opiorphin (Oph) is a naturally produced endogenous peptide with a strong analgesic effect, superior to that of morphine, and without the severe side effects that morphine and morphine-like drugs exert.

Ion-Specific and Solvent Effects on PDADMA–PSS Complexation and Multilayer Formation
Colloids and Interfaces, 2021 Among various parameters that influence the formation of polyelectrolyte complexes and multilayers, special emphasis should be placed on ion-specific and solvent effects.

Wetting-Induced Polyelectrolyte Pore Bridging
Membranes, 2021 Active layers of ion separation membranes often consist of charged layers that retain ions based on electrostatic repulsion. Conventional fabrication of these layers, such as polyelectrolyte deposition, can in some cases lead to excess coating to prevent
