We studied the properties of polyelectrolyte multilayer films prepared using technique deposition from solution (dipping) or supplying solutions to surface by spraying. The quality obtained those two techniques was compared find out whether well-established dipping procedure can be replaced with spraying technique. Neutron and X-ray reflectometric studies were performed on samples interest. found that multilayers are thicker, denser less rough than having same number layers, i.e., cycles,
The formation kinetics and structure of supported lipid bilayers embedded with quantum-dots (QDs) depend on the QD size.
The degree of hydrophobicity surfaces is considered a key factor determining the stability wetting films. They are expected to be stable at hydrophilic surfaces, while hydrophobic films should burst leading three phase contact (TPC) formation. We demonstrated, by studying collisions air bubbles with mica covered polyelectrolyte (PE) layers, that for weakly (contact angle below 50°) electric charge surface becomes decisive film stability. Comparison in cationic surfactant solution (DTABr)...
In our work we have focused on the incorporation of magnetite nanoparticles (NPs) into poly(allylamine hydrochloride)/poly(sodium 4-styrenesulfonate) polyelectrolyte multilayers (PEMs). The main goal presented studies was to control two-dimentional ordering NPs within films. depended treatment underlying were uniformly distributed in freshly prepared samples leading an interfacial mixture polyelectrolytes and particles, while a highly concentrated layer NP formed only when PEMs exposed...
The formation of complete supported lipid bilayers by vesicle adsorption and rupture was studied in relation to deposition conditions vesicles underlying cushion formed from various polyelectrolytes. Lipid were zwitterionic 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (POPC) negatively charged 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphoethanolamine (POPE) phosphate buffer pH with or without NaCl addition. Polyelectrolyte multilayer films (PEM) constructed sequential alternately...
The surface properties of polyelectrolyte multilayers (PEMs) obtained <italic>via</italic> sequential adsorption oppositely charged polyions from their solutions and used as cushions for supported lipid bilayers were investigated.
The authors have investigated the formation and electroactive properties of multilayer films poly(allylamine hydrochloride) (PAH) Prussian blue (PB) nanoparticles. were deposited on gold electrode surface using layer-by-layer deposition. Using cyclic voltamperometry, demonstrated that PAH/PB exhibited properties, increasing with number PB layers. They also electrocatalytically active toward reduction oxidation hydrogen peroxide. By introducing conductive polymers, polypyrrole (PPy)...
