In this study, we assessed the biological effect of Ceiba pentandra bark silver nanoparticles (CP-AgNPs) on HCT-116 cancer cells with an emphasis on cell cytotoxicity, quantification of ROS and determination of mitochondria membrane potential. The synthesized Ceiba pentandra bark silver nanoparticles were characterized by UV-vis spectrometer, High-resolution transmission electron microscope (HR-TEM), X-ray diffraction (XRD) and Selected area electron diffraction (SAED). The synthesized silver nanoparticle cytotoxic and apoptotic effects were studied on colorectal cancer cells (HCT-116). The nanoparticles exhibited an inhibitory concentration (IC50) at (60μg/mL). CP-AgNPs significantly inhibited cell viability and changed the morphology of HCT-116 colon cancer cells. Moreover, CP-AgNPs increased the level of reactive oxygen species, induced cell apoptosis in HCT-116 cell lines through the interference of the mitochondrial membrane potential. These results indicated that Ceiba pentandra bark silver nanoparticles (CP-AgNPs) might act as prospective anticancer agents in colon cancer cells.
