Preparation, circular dichroism induced helical conformation and optical property of chitosan acid salt complexes for biomedical applications.


The efficient procedure for preparation of chitosan acid complexes containing aspartic acid, benzilic acid and terephthalic acid moieties in isopropyl alcohol under mild condition has been demonstrated. The ionic complexation between chitosan and the acid is confirmed by FTIR and 1H NMR spectroscopy. The circular dichroism (CD) spectra of chitosan/aspartic… (More)
