Charge Inversion and Layer-by-Layer Assembly of Flexible Polyelectrolytes
We have applied a continuum self-consistent field (SCF) theory to flexible polyelectrolytes on flat surfaces which are either uncharged or carrying the opposite charge as the polyelectrolytes. We examined in detail the effects of various parameters on the polyelectrolyte adsorption and surface charge compensation by the adsorbed polyelectrolytes. The ground-state dominance approximation (GSDA) ...
متن کاملLayer-by-layer deposition of oppositely charged polyelectrolytes on the surface of condensed DNA particles.
DNA can be condensed with an excess of poly-cations in aqueous solutions forming stable particles of submicron size with positive surface charge. This charge surplus can be used to deposit alternating layers of polyanions and polycations on the surface surrounding the core of condensed DNA. Using poly-L-lysine (PLL) and succinylated PLL (SPLL) as polycation and polyanion, respectively, we demon...
متن کاملArchitectural layer-by-layer assembly of drug nanocapsules with PEGylated polyelectrolytes.
150-200 nm diameter capsules containing 60-70 wt % of poorly soluble drugs, paclitaxel and camptothecin, were produced by layer-by-layer (LbL) assembly on drug nanocores in a solution containing uncharged stabilizers. Optimization of capsule shell architecture and thickness allowed for concentrated (3-5 mg/mL) colloids that are stable in isotonic salt buffers. Nanoparticle aggregation during th...
متن کاملA Contact Problem of an Elastic Layer Compressed by Two Punches of Different Radii
The elasticity mixed boundary values problems dealing with half-space contact are generally well resolved. A large number of these solutions are obtained by using the integral transformation method and methods based the integral equations. However, the problems of finite layer thicknesses are less investigated, despite their practical interests. This study resolves a quasi-stationary problem of...
متن کاملElectrochemical behavior of polyphenol oxidase immobilized in self-assembled structures layer by layer with cationic polyallylamine.
We report here a novel bioelectrode based on self-assembled multilayers of polyphenol oxidase intercalated with cationic polyallylamine built up on a thiol-modified gold surface. We use an immobilization strategy previously described by Hodak J. et al. (Langmuir 1997, 13, 2708-2716) Quartz crystal microbalance with electroacustic impedance experiments were carried out to follow quantitatively t...
