    The absorption band at 1640 cm –1, assigned to primary amines of chitosan, significantly diminished for 9R-modified chitosan. In addition, a peak for the amide bond at 1550 cm –1 was clearly observed for 9R-modified chitosan, indicating successful linkage between oligoarginine and chitosan.Author: Soyeon Park, Sang Kyung Lee, Kuen Yong Lee
