SYNTHESIS AND CHARACTERIZATION OF NEW CHITOSAN-O-ETHYL PHOSPHONATE
(Sociedad Chilena de Química, 2005)
Determination of the degree of substitution of modified chitosan by cyclic voltammetry at water/dichloroethane interface
(Elsevier, 2014-12)
The electrochemical behavior of the cationic polymer chitosan-gtmac (Ch-GTMAC), at the polarized water / 1,2-dichloroethane interface was studied. This polymer was obtained by nucleophilic reaction of chitosan (Ch) with ...
Chitosan-Grafted Copolymers and Chitosan-Ligand Conjugates as Matrices for Pulmonary Drug Delivery
(Hindawi Publishing Corporation, 2011-10)
Recently, much attention has been given to pulmonary drug delivery by means of nanosized systems to treat both local and systemic diseases. Among the differentmaterials used for the production of nanocarriers, chitosan ...
Chitosan/(ureasil-PEO hybrid) blend for drug delivery
(Springer, 2014-11-01)
The effect of chitosan addition on the structure and drug release properties of ureasil-polyethylene oxide (U-PEO) hybrid materials was examined. The hybrids and the blends were prepared by the sol-gel route and their ...
WATER VAPOR PERMEABILITY AND MECHANICAL PROPERTIES OF CHITOSAN COMPOSITE FILMS

Thermal studies of chitin-chitosan derivatives
(2012-12-27)
New poly(azo) amino-chitosan compounds were obtained from the azo coupling reaction of N-benzyl chitosan and diazonium salts. The thermal behavior of these compounds was studied by thermogravimetric analysis (TG), differential ...
3(2) Factorial design and response surface analysis optimization of N-carboxybutylchitosan synthesis
(Elsevier Sci LtdOxfordInglaterra, 2005)
Synthesis and evaluation of diethylethylamine-chitosan for gene delivery: Composition effects on the in vitro transfection efficiency
(2013-02-08)
Chitosan has been indicated as a safe and promising polycation vector for gene delivery. However its low transfection efficiency has been a challenging obstacle for its application. To address this limitation, we synthesized ...
Thermal and morphological study of chitosan metal complexes
(Springer, 2017-07-01)
The synthesis of chitosan Schiff bases, N-benzylidene chitosan (CTB), 4-dimethylamino-benzylidene chitosan (CTDB) and 4-nitro-benzylidene chitosan (CTNB), and their interaction with Cu2+, Zn2+ and Ni2+ were studied. The ...
