Quaternized chitosan as support for the assembly of gold nanoparticles and glucose oxidase: Physicochemical characterization of the platform and evaluation of its biocatalytic activity
(ELSEVIER, 2011-01-01)
We report for the first time the use of quaternized chitosan (QCHI) for the immobilization of gold nanopartides (NP) and glucose oxidase (GOD), the characterization of the resulting platform and its biocatalytic activity ...
Chromium retention properties of N-alkyl quaternized poly(4-vinylpyridine)
(2009)
The ability of solid N-alkyl quaternized poly(4-vinylpyridine) with hexyl, octyl and decyl bromide for the retention of chromate and dichromate forms of Cr(VI) in aqueous solutions is studied. The retention of Cr(VI) was ...
Synthesis and characterization of poly (ionic liquid) derivatives of N-alkyl quaternized poly(4-vinylpyridine)
(Elsevier B.V., 2018)
© 2018 Elsevier B.V. The main motivation of this work is to obtain poly (ionic liquids) (PILs) derived from poly (4-vinyl pyridine) of different hydrophobic character containing BF4 −, PF6 −, (CF3SO2)2 N− and CF3SO3 − as ...
Adsorption of poly-2-(dimethylamino) ethylmethacrylate-N-alkyl quaternized at the water/chloroform interface
(ELSEVIER SCIENCE BV, 2010-05-04)
The interfacial properties of poly-2-(dimethylamino) ethyl methacrylate-N-alkyl quaternized with octyl,
decyl, dodecyl and tetradecyl bromide are studied from the chloroform to the water/chloroform interface.
In order ...
Synthesis and characterization of poly (ionic liquid) derivatives of N -alkyl quaternized poly (4-vinylpyridine)
(Elsevier, 2018)
The main motivation of this work is to obtain poly (ionic liquids) (PILs) derived from poly (4-vinyl pyridine) of different hydrophobic character containing BF4-, PF6-, (CF3SO2)(2) N- and CF3SO3- as counterions. PILs were ...
Solubilization of phenol derivatives in polymer micelles formed by cationic block copolymer
(Hindawi, 2017)
The aggregation of cationic block copolymers formed by polystyrene (PS) and poly(ethyl-4-vinylpyridine) (PS-b-PE4VP) was studied in aqueous solution. Diblock copolymers of PS and poly(4-vinylpyridine) were synthesized by ...
Lysozyme binding to poly(4-vinyl-N-alkylpyridinium bromide)
(2009)
The adsorption behavior of polycations at ionic strengths (I) ranging from 0.001 to 0.1 onto silicon wafers was studied by means of ellipsometry, contact angle measurements and atomic force microscopy (AFM). Polycations ...
Protein Adsorption onto Polyelectrolyte Layers: Effects of Protein Hydrophobicity and Charge Anisotropy
(AMER CHEMICAL SOC, 2010-07-04)
Ellipsometry was used to investigate the influence of ionic strength (I) and pH on the adsorption of bovine serum
albumin (BSA) or β-lactoglobulin (BLG) onto preabsorbed layers of two polycations: poly(diallyldimethylam ...
Hybrid ternary organic-inorganic films based on interpolymer complexes and silica
(ELSEVIER SCI LTD, 2004-05-11)
Homogeneous transparent hybrid films consisting of chitosan (CHI), poly(monomethyl itaconate) (PMMI) and silica were obtained indicating the absence of microphase separation. These ternary hybrid materials are very interesting ...
Inhibiting Pathogen Surface Adherence by Multilayer Polyelectrolyte Films Functionalized with Glucofuranose Derivatives
(American Chemical Society, 2018)
© 2018 American Chemical Society. Inhibiting pathogenic bacterial adherence on surfaces is an ongoing challenge to prevent the development of biofilms. Multilayer polyelectrolyte films are feasible antibacterial materials. ...
