STUDIES ON THE USABLE PROPERTIES OF INNOVATIVE WOUND DRESSINGS
Journal Title: Progress on Chemistry and Application of Chitin and its Derivatives - Year 2012, Vol 0, Issue
Abstract
The new implemented wound dressings should meet several requirements connected with the clinical safety and performance. The series of PN-EN 13726 Standards describes the tests methods for the verification the most important parameters related to mentioned performance and safety of a new designed wound dressing being the base for the risk analysis (according to PN-EN ISO 14971:2009 Standard). The aim of the research was to evaluate the behavior of several types of new designed prototypes of innovative wound dressings made of various form of chitosan (such as: foams, films, etc.). The behavior of studied chitosan wound dressings was evaluated before and after of accelerated aging according to ASTM F 1980-07:2002 to establish the effect of the wound dressings storing conditions. The presented study is a continuation of earlier research.

HIGHLY SENSITIVE CHITOSAN-BASED OPTICAL FLUORESCENT SENSOR FOR GASEOUS METHYLAMINE DETECTION
An optical fluorescent sensor based on a chitosan thin film co-doped with Eu3+ and a bromothymol blue pH indicator has been developed. Near-UV to visible (350–400 nm) excitation of the europium (III) chelate complexes wi...
BEHAVIOUR OF TiO2/CHITOSAN DISPERSION AS A FUNCTION OF SOLUTION pH
This paper presents the physico-chemical characteristics of titanium dioxide/chitosan dispersion. The surface and electrostatic properties of TiO2 particles in the electrolyte solution (NaCl) and in the presence of a bio...
THE PROPERTIES OF THERMOSENSITIVE GYNECOLOGICAL POWDERS CONTAINING LACTIC ACID COMPLEXED WITH CHITOSAN
The investigations showed that the addition of a 20%, 23% and 25% poloxamer 407 increases the adhesive properties of the investigated powders, but at the same time it increases their pH. The enrichment of the composition...
THE EFFECT OF A HYDROPHILIZING SUBSTANCE ON THE PROPERTIES OF THERMOSENSITIVE HYDROPHILIC GELS CONTAINING LACTIC ACID COMPLEXED WITH CHITOSAN
Abstract Commonly applied drug forms tend to leave the vagina when the patient assumes an upright position. Permanent contact of the drug form with the vaginal mucosa during daily activities of the patient is an indispen...
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...
