Model layer-by-layer (LbL) assemblies of poly(allylamine hydrochloride) (PAH) and hyaluronic acid (HA) were fabricated in order to study their wet adhesive behavior. The film characteristics investigated understand the inherent structures during assembly process. Subsequently, adhesion these systems was evaluated correlation between structure energy required separate LbL assemblies. We describe how conditions fabrication can be utilized control films. formation are examined absence presence...
The bioactivity, biological fate and cytotoxicity of nanomaterials when they come into contact with living organisms are determined by their interaction biomacromolecules barriers. In this context, the role symmetry/shape anisotropy both interfaces in mutual interaction, is a relatively unaddressed issue. Here, we study gold nanoparticles (NPs) different shapes (nanospheres nanorods) biomimetic membranes morphology, i.e. flat (2D symmetry, representative most common plasma membrane...
Abstract We propose that a testing procedure we call wet-peel significantly augments conventional wet paper when comparing wet-strength resin efficacy or the influence wood pulp fiber surface treatments on strength. A thin layer of is sandwiched between pair thin, regenerated cellulose membranes to form laminate, which physical model for fiber-fiber joints in paper. In method, ninety-degree wet-delamination force gives direct measure adhesion cellulose-cellulose joint. Wet-peel measurements...
Hydrazide-derivatized poly(N-isopropylacrylamide-co-acrylic acid) microgels gave strong adhesion to wet, TEMPO oxidized, regenerated cellulose membranes without a drying or heating step. Adhesion was attributed hydrazone covalent bond formation with aldehyde groups present on the surfaces. This is one of only three chemistries we have found that gives significant never-dried between wet By contrast, for joints been dried and heated before testing, hydrazide-hydrazone chemistry offers no...
The phase behavior of lactoferrin has been studied as a function concentration at pH and ionic strength where is known to interact effectively via patch–patch attraction. In contrast isotropic attractive potentials, the directional attraction gives rise different or solution behavior. At low concentrations, protein dimerizes. As increased, self-assembles into elongated, stripe-like structures intermediate which predicted for case one-patch colloids. stripe surprisingly difficult detect using...
Adsorption of a single layer molecules on surface, or even reorientation already present molecules, can significantly affect the surface properties material. In this study, vibrational sum frequency spectroscopy (VSFS) has been used to study change in molecular structure at solid–air interface following thermal curing polyelectrolyte multilayers poly(allylamine hydrochloride) and poly(acrylic acid). Significant changes VSF spectra were observed after curing. These accompanied by distinct...
Layer-by-layer (LbL) assemblies of polyvinylamine with grafted TEMPO moieties (PVAm-T) sodium polystyrenesulfonate (PSS) were prepared on gold-sulfonate surfaces, and the redox properties measured by cyclic voltammetry. LbL compositions probed quartz crystal microbalance (wet) ellipsometric (dry) film measurements. Approximately 30% in redox-active when total coverage was varied up to 6 μmol/m2, either varying content PVAm-T or number bilayers. Three non-redox-active PVAm/PSS blocking...
The use of DEHP (diethylhexyl phthalate) is now banned for most applications in Europe; the exception blood bags, where its toxicity overshadowed by ability to extend storage life red cells. Another plasticiser, BTHC (butanoyl trihexyl citrate), used paediatric bags but does not stabilise cells as effectively. Interactions between plasticisers and lipids are investigated with a phospholipid, DMPC, understand increased stability presence well bioaccumulation identify differences BTHC. Mixed...
When nanomaterials are put in contact with living organisms, their interaction biomacromolacules and biological barriers will determine bioactivity, fate cytotoxicity. In this context, the role of symmetry/shape anisotropy both interfaces on mechanism, is a relatively unaddressed issue. Here, we study gold nanoparticles (NPs) different shape (nanospheres nanorods) biomimetic membranes symmetry, i.e. flat (of 2D representative most common plasma membrane geometry), cubic 3D non-lamellar...
