Chitosan and its derivatives for gene delivery
International Journal of Biological Macromolecules, 2011Gene delivery can particularly be used for the treatment of diseases by the insertion of genetic materials (DNA and RNA) into mammalian cells either to express new proteins or to prevent the expression of existing proteins. Chitosan, a natural polymer is nontoxic, biocompatible, and biodegradable and it is used as a support material for gene delivery ...

Mercury sorption on a thiocarbamoyl derivative of chitosan
Journal of Hazardous Materials, 2009The grafting of thiourea on chitosan backbone allows synthesizing a thiocarbamoyl derivative that was very efficient for mercury sorption in acidic solutions. Though the sorption capacity is not increased compared to raw chitosan in near neutral solutions, this modification allowed maintaining high sorption capacity (close to 2.3 mmol Hg g(-1)) at pH 2.

Derivatives of Chitin and Chitosan
1992Compared with the extensive research that has been carried out on both the production and the properties of cellulose nitrate,1 because of its commercial importance as an explosive and as a plastic, very little research has been carried out on the nitration of chitin and chitosan.
