Polyelectrolyte multilayers for enhancing cell adhesion and potential applications in tissue engineering
(Asociación Química Argentina, 2018-10)
Polyelectrolyte multilayers (PEMs) assembled by de Layer by Layer (LbL) technique offer multiplepossibilities for surface engineering as an alternative to covalent chemistry. PEMs have recently attractedattention as a mean ...
Tailored polyelectrolyte thin film multilayers to modulate cell adhesion
(American Institute of Physics, 2017-10)
The layer-by-layer assembly of polyelectrolyte multilayers (PEMs) from natural or synthetic polyelectrolytes constitutes a very versatile and simple strategy to modify surfaces and modulate cell behavior. PEMs assembled ...
Polarity studies of single polyelectrolyte layers in polyelectrolyte multilayers probed by steady state and life time doxorubicin fluorescence
(Elsevier, 2022-02)
Hypothesis: Polarity in polyelectrolyte multilayers (PEMs) may vary from the inner to the top layers of the film as the charge compensation of the layers is more effective inside the PEMs than in outer layers. Doxorubicin ...
A friendly method for Raphanus sativus L (wild radish) peroxidase purification by polyelectrolyte precipitation
(Elsevier Science, 2013-11)
The separation of radish peroxidase from a fresh Raphanus sativus L extract was carried out using precipitation with two commercially available negatively charged synthetic polyelectrolytes: Eudragit® L 100 and Eudragit® ...
Microphase separation and aggregate self-assembly in brushes of oppositely charged polyelectrolytes triggered by ion pairing
(American Institute of Physics, 2020-10)
This work applies a molecular theory to study the formation of lateral self-assembled aggregates in mixed brushes composed of polyanion and polycation chains. In order to overcome the well-known limitations of mean-field ...
Voltage-Triggered Structural Switching of Polyelectrolyte-Modified Nanochannels
(American Chemical Society, 2020-03)
Synthetic solid-state nanochannels modified with polyelectrolyte brushes are an important class of stimuli-responsive nanofluidic devices. This work theoretically addresses the design of a voltage-triggered nanomechanical ...
Surfactant presence in a multilayer polyelectrolyte-enzyme system improves its catalytic response
(Elsevier Science Inc, 2009-05)
Self-assembling of poly(allylamine) containing an osmium polypyridil complex (PAOs) alternatively with sodium dodecyl sulfate (SDS) and glucose oxidase (GOx) generates a ternary multilayer system, (PAOs/SDS/PAOs/GOx)n. The ...
Metal-ion responsive redox polyelectrolyte multilayers
(Royal Society of Chemistry, 2010-10)
We present polyelectrolyte multilayer modified electrodes exhibiting novel chemically responsive redox behaviour due to the combination of both redox and metal-ion–ligand functionalities on the same sites.
Electron Transfer in SAM/Cytochrome/Polyelectrolyte Hybrid Systems on Electrodes: A Time-Resolved Surface-Enhanced Resonance Raman Study
(American Chemical Society, 2007-10)
Silver electrodes were covered with mixed self-assembled monolayers (SAMs) of 11-mercaptoundecanoic acid (MUA) and 11-mercaptoundecanol (MU) and subsequently coated with alternating layers of cytochrome c (Cyt) and ...
Fabrication and Characterization of Hollow Microcapsules from Polyelectrolytes Bearing Thymine Pendant Groups for Ultraviolet-B (UVB)-Induced Crosslinking
(Wiley-VCH, 2019-05)
DNA - bioinspired polyelectrolytes poly[vinylbenzylthymine (VBT)-4-vinylbenzyltriethylammonium chloride (VBA)] and poly[vinylbenzylthymine (VBT)-4-vinylphenylsufonate (VPS)] were used for the preparation of hollow microcapsules ...
