PREPARATION AND CHARACTERIZATION OF CRYOGELS BASED ON PECTIN AND CHITOSAN
Journal Title: Progress on Chemistry and Application of Chitin and its Derivatives - Year 2016, Vol 0, Issue
Abstract
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 Apple pectin/Chitosan cryogels and from 9.44 to 17.64 % for Heracleum pectin/Chitosan cryogels. Internal structure and porosity of the cryogels were measured by scanning electron microscopy. According to the scanning electron microscopy, cryogels have a macroporous sheet-like structure. In the future, cryogels can be used in biotechnology and medicine as biocompatible, biodegradable materials.

STUDIES ON ADSORPTION CHLORAMFENICOL ON CHITOSANS IN PHARMACEUTICAL “IN VITRO” MODEL
In clinical practice in the treatment of obesity, uses several natural macromolecular compounds, whose functioning is based on supporting the weight loss. In use of dietary supplements containing chitosan, sometimes reac...
PLA MICROGRANULES USED AS CARRIERS OF ACTIVE SUBSTANCES PREPARED BY EMULSIFICATION IN CHITOSAN SOLUTION
The aim of research was the preparation of poly(lactide) and chitosan composite of spherical structures by emulsyfication of both polymers solutions. This resulted in fabrication of PLA microstructures (mPLA) suspended i...
THE ROLE OF CHITOSAN IN AKT KINASE REGULATION ACTIVITY
A decrease in migration of tumor cells incubated with the investigated chitosan preparations was correlated with a decreased activity of MMP-2 and MMP-9 metalloproteinases, what significantly affected inhibition of tumor...
NEW HOMOGENEOUS BLENDS OF DIBUTYRYLCHITIN AND ALIPHATIC POLYESTERS
The results of physical modification of dibutyrylchitin (DBCH) for the purpose of improvement of its imperfect mechanical properties are presented. Thus, the novel blends of DBCH and biodegradable aliphatic copolymer der...
APPLICATION OF CHITOSAN IONICALLY CROSSLINKED WITH SODIUM EDETATE FOR REACTIVE DYES REMOVAL FROM AQUEOUS SOLUTIONS
In this study, we investigated the effect of chitosan crosslinking with sodium edetate (SE) on its sorption capacity of Reactive Black 5 and Reactive Yellow 84 dyes. The first stage of the study allowed establishing cond...
