Comparative studies on polyelectrolyte complexes and mixtures of chitosan-alginate and chitosan-carrageenan as prolonged diltiazem clorhydrate release systems
(ELSEVIER SCIENCE BV, 2004-01)
The aim of this work was to evaluate the possibility of using mixtures and/or polyelectrolyte complexes from both chitosan-alginate and chitosan-carrageenan as prolonged drug release systems. Different dissolution profiles ...
Selective crystallization of calcium salts by poly (acrylate)-grafted chitosan
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2005-06-01)
The biopolymer chitosan was chemically modified by grafting polyacrylamide or polyacrylic acid in a homogeneous aqueous phase using potassium persulfate (KPS) as redox initiator system in the presence of N,N-methylene-bi ...
Chitosan thymol nanoparticles improve the antimicrobial effect and the water vapour barrier of chitosan-quinoa protein films
(Elsevier Ltd, 2019)
The aim of this work was to improve the performance of quinoa protein/chitosan edible films on the extension of postharvest life of blueberries and tomato cherries by addition of chitosan thymol nanoparticles prepared by ...
Synergistic effects of crosslinking and chitosan molecular weight on the microstructure, molecular mobility, thermal and sorption properties of porous chitosan/gelatin/hyaluronic acid scaffolds
(Wiley, 2017)
In this study, synergistic effects of crosslinking and chitosan molecular weight on the microstructure, molecular mobility, thermal, and sorption properties of porous chitosan/ gelatin/ hyaluronic acid hybrid foams are ...
Chitosan formulations improve the immunogenicity of a GnRH-I peptide-based vaccine
(Elsevier, 2009-03-18)
Three chitosan formulations were evaluated for their ability as adjuvant of a poor immunogenic peptide vaccine against GnRH-I. Male Sprague-Dawley rats were immunized subcutaneously with recombinant His-GnRH-tandem-repeat ...
Chitosan based films. synthesis and crystalline properties of nanocomposites with amine propyl siloxane
(1997)
The sol-gel treatment of equal amounts of chitosan and partially hydrolyzed aminopropylsiloxane (APS) leads to the formation of transparent, flexible films indicating high compatibility at the molecular level of the ...
Lithium ion conductivity of molecularly compatibilized chitosan–poly (aminopropyltriethoxysilane)–poly(ethylene oxide) nanocomposites
(Elsevier , Science Ltd., 2007-05-31)
Films of composites of chitosan/poly(aminopropyltriethoxysilane)/poly(ethylene oxide) (CHI/pAPS/PEO) containing a fixed amount of lithium
salt are studied. The ternary composition diagram of the composites, reporting ...
Hybrid Chitosane-Mercaptopropylsiloxane Films - Synthesis and Properties
(TAYLOR & FRANCIS LTD, 2010)
A series of new Chitosan=poly(mercaptopropysiloxane) hybrid films were obtained
by blending mercaptopropylsiloxane oligomers (pMPS) with chitosan (CHI). The
MPS oligomers were prepared by sol-gel using as precursor ...
Thermal effect on the microhardness of chitosan films
(2000)
In this communication we present the results obtained from a study on the effect of thermal treatments of chitosan films with different molecular weights, but with a similar acetilation degree, carried out by microhardness. ...
Transparent conducting polymer electrolyte by addition of lithium to the molecular complex chitosane -poly (aminopropyl siloxane)
(Elsevier , Science Ltd., 2002-05-19)
Transparent lithium-ion conducting films were prepared by adding lithium perchlorate to a mixture of chitosane (CHI) and
poly(aminopropylsiloxane) (pAPS) in a molar ratio 0.6:1 by sol /gel methods. The morphological and ...
