In this tnesis, the oligochitosan was selected as fundamental raw material, and the acetylsulface was selected as sulfonating agent. Based on the two raw materials sulphonated chitosan was prepared and nanocrystalizated. Solid supported drugs [1.5-dimethyl-2-phenyl-3-oxygen subsititued-2,3-dihydro-lH-Pyrazole-4-yl)methylamino] methyl sulfonic acid sodium salt (metamizole sodium tablets) were prepared as MnFe2O4magnetic composited macrosphere coating with sulphonated Chitosan or sulphonated chitosan nanopart...
