The nano chitosan-oligosaccharide/Fe complex was prepared by addition of FeCl3 to chitosan-oligosaccharide solution, the molecular weight of which was about 5000. The complex was characterized by FTIR, UV spectra and DTA, TEM and PCS method. It was concluded that the Fe(III) was coordinated with the NH2 of chitosan-oligosaccharide. And the ultraviolet spectroscopy analysis and gel electrophoresis analysis were used to research the biological activity of chitosan-oligosaccharide and chitosan-oligosaccharide/Fe complex via plasmid DNA. The result indicated that the chitosan-oligosaccharide/Fe complex had a strong binding affinity with DNA and the complex could damage and degrade DNA.
Key words: chitosan-oligosaccharide, chitosan-oligosaccharide/Fe complex, plasmid DNA, ultraviolet spectroscopy analysis, gel electrophoresis analysis, biological activity
