Gallic acid-loaded chitosan nanoparticles enhance the DNA damage and apoptotic features through inhibiting flap endonuclease-1 in triple-negative breast cancer cells.

This study investigated the fabrication of gallic acid-loaded chitosan nanoparticles (Gal-Chi-NPs) that enhanced the DNA damage and apoptotic features by inhibiting FEN-1 expressions in MDA-MB 231 cells. Gal-Chi-NPs were fabricated by the ionic gelation method, and it was characterized by several studies such as dynamic light spectroscopy, Fourier-transforms infrared spectroscopy, x-ray diffraction, scanning electron microscopy, energy-dispersive x-ray, atomic force microscopy, and thermogravimetric analysis. We have obtained that Gal-Chi-NPs displayed 182.
