FORMATION AND CHARACTERIZATION OF SUCCINOYL CHITOSAN PARTICLES LOADED WITH WARNERIN
Journal Title: Progress on Chemistry and Application of Chitin and its Derivatives - Year 2015, Vol 0, Issue
Abstract
This study aims to obtain nanoparticles based on succinoyl chitosan loaded with Warnerin (War-SCNPs), low molecular weight cationic peptide. The nanoparticles of succinoyl chitosan (SCNPs) were prepared by salt coacervation method, and Warnerin loading efficiency on SCNPs was reached 75% in the optimum conditions, particularly, ration (SCNPs : peptide) was equal to (1.75 : 1, μg / ml ). Formed War-SCNPs were stable, had a weak electric charge from (-4.4) to (-14,6) mV. Determining of SCNPs size showed that a main fraction of SCNPs had the size of 160 nm, and after the peptide sorption War-SCNPs size increased up to 330 nm. The experimental data of this study will likely impact War-SCNPs use as therapeutic delivery systems of the peptide to be administered parenteral.

Studies on the Dyeing of Chitin and Chitosan with pre-metallised Dyes at Neutral pH
Both 1:1 pre-metallised acid dyes and pre-coppered direct dyes, but not 1:2 pre-metallised acid dyes, have been shown to readily dye chitin and chitosan from neutral dyebaths. With the 1:1 pre-metallised acid dyes the ad...
USE POLYVINYLPYRROLIDONE IN TECHNOLOGY OF GYNAECOLOGICAL POWDERS CONTAINING LACTIC ACID COMPLEXED WITH CHITOSAN
Gels obtained from powders containing lactic acid complexed with chitosan reveal a stoichiometric ratio of 1:1, 2:1, 3:1, 4:1 and 8:1. Their pH ranged from 3.92 to 4.44 for 1:1 gels and from 2.36 to 2.84 for the 8:1 rati...
THE USE OF ACTIVE CARBON IMMOBILISED ON CHITOSAN BEADS FOR RB5 AND BV10 DYE REMOVAL FROM AQUEOUS SOLUTIONS
This paper presents the adsorption of dyes – the anionic Reactive Black 5 (RB5) and cationic Basic Violet 10 (BV10) dyes – on activated carbon (AC) immobilised on chitosan (CHs). The results were compared with the remova...
CHARACTERISATION OF THIN CHITOSAN FILMS FOR GUIDED TISSUE REGENERATION PURPOSES
The morphology and structure of thin films containing chitosan (Ch) with montmorillonite (MMT) were characterised by scanning electron microscopy (SEM), atomic force microscopy (AFM) and attenuated total reflectance Four...
STUDIES OF NORFLOXACIN ADSORPTION ON CHITOSAN
assisting weight loss are used in the obesity treatment. These measures swell in the digestive tract and form the polymer gel system, which has the ability to adsorb up to 5 times more lipids relative to its own weight....
