Effect of ionic strength solution on the stability of chitosan-DNA nanoparticles
(2013-07-01)
Chitosan-DNA nanoparticles employed in gene therapy protocols consist of a neutralised, stoichiometric core and a shell of the excess of chitosan which stabilises the particles against further coagulation. At low ionic ...
Removal of Fluoride from Aqueous Solution Using Aluminum-Impregnated Chitosan Biopolymer
(Taylor & Francis IncPhiladelphiaEUA, 2009)
Trimethylchitosan hydrochloride obtained from lobster carapace chitin on a bench scale
(Biointerface Research Applied Chemistry, 2019-10-15)
Starting from the chitin obtained from the lobster carapace, chitosan was obtained. This polymer, due to its high biodegradability, biocompatibility and mucoadhesivity, has a wide use in the pharmaceutical and food industry. ...
Novel colloidal nanocarrier of cetylpyridinium chloride: Antifungal activities on candida species and cytotoxic potential on murine fibroblasts
(2020-12-01)
Nanocarriers have been used as alternative tools to overcome the resistance of Candida species to conventional treatments. This study prepared a nanocarrier of cetylpyridinium chloride (CPC) using iron oxide nanoparticles ...
Chitosan as a Bioadhesive Agent Between Porphyrins and Phospholipids in a Biomembrane Model
(AMER SCIENTIFIC PUBLISHERS, 2011)
Porphyrins are currently used in photodynamic therapy as photosensitizers. In this paper we studied the interaction of two charged porphyrins, 5, 10, 15, 20-mesotetrakis(N-metyl-4-pyridyl) porphyrin, (TMPyP/chloride salt) ...
N-(2-hydroxy)-propyl-3-trimethylammonium, O-palmitoyl chitosan: Synthesis, physicochemical and biological properties
(Elsevier B.V., 2021-05-01)
Two samples of N-(2-hydroxy)-propyl-3-trimethylammonium, O-palmitoyl chitosan (DPCat) with different av-erage degrees of quaternization named as DPCat35 (DQ = 35%) and DPCat80 (DQ = 80%), were successfully syn-thesized by ...
Hydrogels Based On Alkylated Chitosan And Polyelectrolyte Copolymers
(2018)
Hydrogels formed by alkylated chitosan with N-(3-chloro-2-hydroxypropyl) trimethylammonium chloride and synthetic copolymers forming polyelectrolyte complexes are presented. The copolymer polyelectrolytes were synthesized ...
Synthesis and unisual swelling behavior of combined cationic/non-ionic hydrogels based on chitosan
(2003)
Hydrogel-forming copolymers based on chitosan grafted with different amounts of polyacrylamide were synthesized and its swelling capacity determined in distilled water, sodium chloride solutions, as well as in buffer ...
Physicochemical properties of a mucin/chitosan matrix used for the development of an oxalate biosensor
(Elsevier, 2010-09)
Immobilization conditions of biomolecules play an important role in a biosensor performance. In this paper the response of amperometric electrodes for oxalate is related with some physicochemical properties of the matrices ...
