Fourier Transform Infrared (FTIR) Spectroscopy: FTIR was used to confirm the formation of MOF nanoparticles and determine functional groups of final components using a Perkin Elmer Frontier vibrational spectrophotometer (Spectrum 100, PerkinElmer Inc., USA). The particles were first lyophilized and then measured at room temperature in a wave number range of 4000-600 cm -1 with a resolution of 2 cm -1 against the KBr background.
