A novel cerium(iii)-isatin Schiff base complex: spectrofluorometric and DFT studies and application as a kidney biomarker for ultrasensitive detection of human creatinine.

In this paper, a new isatin-Schiff base L1 was prepared a simple reaction of isatin with 2-amino-3-hydroxypyridin. Subsequently, cerium(iii)-Schiff base complex C1 was obtained through the reaction of the prepared Schiff base L1 with cerium chloride a hydrothermal method. The prepared L1, as well as C1, were fully characterized using many spectroscopic techniques, such as mass spectra, elemental analysis, UV-vis, FT-IR, H-NMR, C-NMR, FE-SEM/EDX, and HR-TEM.
