HYDROXYAPATITE - CHITOSAN BIOCOMPOSITES
Journal Title: Progress on Chemistry and Application of Chitin and its Derivatives - Year 2008, Vol 0, Issue
Abstract
Both samples of HAp form with chitosan and it’s useful forms (MKCh, chitosan lactate) well shaped 3-dimentional forms – sponges. The sponges can be used as implants in orthopedic surgery. 3-dimentional structures of HAp/chitosan composites are a good base for scaffolds productin.

ISOLATION, MOLECULAR CLONING AND CHARACTERISATION OF TWO GENES CODING CHITIN DEACETYLASE FROM MUCOR CIRCINELLOIDES IBT-83
Chitosan is a linear N-deacetylated derivative of chitin, soluble in acetic solutions. The deacetylation of chitin can be achieved enzymatically using chitin deacetylase (ChDa) (EC 3.5.1.41), which hydrolyses the N-aceta...
THE STRENGTH OF CHITOSAN FILMS. THE ROLE OF MOLECULAR WEIGHT, THE DEGREE OF ORDER, THE NATURE OF CONTRE-ION
The deformational-strength characteristics of chitosan films with different molecular weight and the degree of deacetylation derived from water-acid solutions with different nature and concentration have been researched....
EFFECT OF A POLYVINYL ALCOHOL AND SELECTED AUXILIARY SUBSTANCES ON THE PROPERTIES OF THERMOSENSITIVE HYDROPHILIC GELS CONTAINING LACTIC ACID COMPLEXED WITH CHITOSAN
Gels containing lactic acid complexed with chitosan at a stechiometric ratio 1:1 and 2:1 and 5-25% content of PEG-200 reveal pH from 3.42 to 4.95. The addition of 20 – 25% poloxamer 407 increases the pH from 4.55 to 5.30...
INFLUENCE OF UV-IRRADIATION ON MOLECULAR WEIGHT OF CHITOSAN
In the present paper the results regarding the influence of UV-irradiation with 254 nm wavelength on the molecular weight of chitosan are presented. The concentration of chitosan solution was 0.5%(w/w) in 0.1 M acetic ac...
MOLECULAR STRUCTURE AND FORMATION OF CHITOSAN AND PECTIN BASED THIN FILMS
In this study using methods of Atomic force microscopy (AFM) and Quartz crystal microbalance with dissipation monitoring (QCM-D) the special characteristics of formation and architecture of thin films coatings based on n...
