Preparation and characterization of N-alkylated chitosan derivatives.

The article presents a study which investigates the characterization of nitrogen (N)-alkylated chitosan derivates. The study synthesized the said chitosan in water which contains acetic acid by the Michael addition reaction. The discussion of various methods used in the study such as fourier transform infrared (FTIR) spectroscopy, antibacterial activity tests, and X-ray diffraction (XRD) were also included. The XRD analysis reveals that chitosan derivatives were amorphous.
