Fluorescent Property of Chitosan Oligomer and Its Application as a Metal Ion Sensor
An aqueous solution was successfully prepared using a low-molecular-weight chitosan oligomer and FITC, and its structural and fluorescent properties were observed by using 1H NMR, 13C NMR, FT-IR, XRD, UV-Vis, and PL spectrometry. Its application as a metal ion sensor was also evaluated. The fluoresc...
