AB In our current study, we synthesized silver nanoparticles (AgNPs) from an aqueous seed extract of Nigella sativa. The seed extract contains phytochemical compounds including phenols, terpenoids, and flavonoids that may act as reducing agents and are able to convert metal ions to metal nanoparticles. The formation of synthesized AgNPs was characterized using UV-visible spectroscopy, Fourier transform infra-red spectroscopy (FT-IR), scanning electron microscopy (SEM) and energy dispersive analysis of X-rays (EDX). The efficacy of N-AgNPs against human breast cancer (MCF-7) cells was tested. The synthesized AgNPs displayed dose-dependent cytotoxicity (1−200 µg/mL) against MCF-7 cells. Morphological alterations of the cells also appeared as bright field images. Treatment of synthesized AgNPs altered the expression of Bax and Bcl-2 (apoptotic proteins) and COX-2 (inflammatory marker) in MCF-7 cells. To our knowledge, this is the first report demonstrating that N-AgNPs from Nigella sativa can induce apoptosis in MCF-7 cells.
