Abstract:

A pre-column derivatization method was developed to analyze polyamidoamine (PAMAM) dendrimers. The fluorescein isothiocyanate (FITC) derivation method improved the retention of PAMAM dendrimers on the reversed-phase column of high performance liquid chromatography (RP-HPLC). The derivation benefited the UV-Vis detection of PAMAM, although the fluorescence of FITC was quenched by PAMAM dendrimers. The primary amine-terminated PAMAM dendrimers, generation 3 (PAMAM-NH2 (G3)), were quantitatively determined by UV- Vis spectroscopy over the concentration range of 10-80 mu g mL (- 1), with the calibration curve expressed as A = 131.6C (mu g mL (- 1)) - 295.6 (R-2 = 0.9901) and the detection limit of 2.7 mu g mL - (1). The binding ratio of FITC to PAMAM-NH2 (G3) was determined as 8:1 by liquid chromatography-electrospray ionization-ion trap mass spectrometry (LC-ESI- IT-MS).
