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.

POLYMER BIOCOMPOSITES USED IN BEDSORES TREATMENT
Investigations are presented in the preparation of composite dressing material based on two biopolymers -chitosan and sodium alginate with the addition of sulfanilamide as medication designed for the healing of bedsores....
EQUILIBRIUM SWELLING STUDY OF CROSSLINKED CHITOSAN MEMBRANES IN WATER, BUFFER AND SALT SOLUTIONS
Physically crosslinked membranes were prepared by treating chitosan (Ch) with pentasodium tripolyphosphate (TPP) at different reaction conditions. The equilibrium swelling ratio, Seq, of Ch/TPP membranes in water, buffer...
SALICYLIC ACID RELEASE FROM CHITOSAN PELLETS COATED WITH POLYLACTIDE
The aim of the study was to prepare a bi-polymer drug carrier composed of chitosan pellets (CS) coated with polylactide shell (PLA) providing prolonged model drug – salicylic acid (SA) release into phosphate buffer of pH...
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...
PREPARATION AND CHARACTERIZATION OF CRYOGELS BASED ON PECTIN AND CHITOSAN
Novel cryogels based on pectin and chitosan were obtained by a cryotropic gelation method. Percentage of chitosan in the cryogels was estimated by elemental analysis. The obtained values were from 3.50 to 15.03 % for App...
